People experiencing severe and multiple disadvantage (SMD) have disproportionately high levels of dental disease and tooth loss but have limited access to dental care. This paper presents an evidence-based case study of co-designing, implementing, evaluating and refining a community dental clinic for people experiencing SMD in the Southwest of England. It shares challenges, lessons, and solutions. Tailored interventions that coordinate flexible and responsive care are important for facilitating dental access for individuals experiencing SMD. Participatory approaches can deliver a range of impacts both on research and service development. No single fixed model of co-design can be applied in service development, and the choice will vary depending on local context, available resources and joint decision making. Through co-design, vulnerable populations such as those with SMD can shape dental services that are more acceptable, appropriate and responsive to their needs. This approach can also ensure long-term sustainability by bridging treatment pathway development and commissioning., Competing Interests: RW is the Chief Executive Officer of PDSE.

Background: People experiencing homelessness co-occurring with substance use or offending ('severe and multiple disadvantage' SMD) often have high levels of poor oral health and related health behaviours (particularly, substance use, smoking, poor diet). This systematic review aimed to assess the effectiveness and cost-effectiveness of interventions in adults experiencing SMD to improve oral health and related health behaviours., Methods and Findings: From inception to February 2023, five bibliographic databases (MEDLINE, EMBASE, PsycINFO, CINAHL, and Scopus) and grey literature were searched. Two researchers independently screened the search results. Randomized controlled trials (RCTs), comparative studies and economic evaluations were included that reported outcomes on oral health and the related health behaviours. Risk of bias was assessed and results narratively synthesized. Meta-analyses were performed where appropriate. This review was registered with PROSPERO (reg. no: CRD42020202416). Thirty-eight studies were included (published between 1991 and 2023) with 34 studies reporting about effectiveness. Most studies reported on substance use (n = 30). Interventions with a combination of housing support with substance use and mental health support such as contingent work therapy appeared to show some reduction in substance use in SMD groups. However, meta-analyses showed no statistically significant results. Most studies had short periods of follow-up and high attrition rates. Only one study reported on oral health; none reported on diet. Three RCTs reported on smoking, of which one comprising nicotine replacement with contingency management showed improved smoking abstinence at 4 weeks compared to control. Five studies with economic evaluations provided some evidence that interventions such as Housing First and enhanced support could be cost-effective in reducing substance use., Conclusion: This review found that services such as housing combined with other healthcare services could be effective in improving health behaviours, particularly substance use, among SMD groups. Gaps in evidence also remain on oral health improvement, smoking, and diet. High quality studies on effectiveness with adequate power and retention are needed to address these significant health challenges in SMD populations., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 McGowan et al.

Background: The term 'care-experienced' refers to anyone who is currently in care or has been in care at any stage in their life. A complex interplay of factors leads to care-experienced children and young people (CECYP) experiencing poorer oral health and access to dental care than their peers. A rapid review of the co-production of health and social care research with vulnerable children and young people (CYP) was carried out to inform the development of a co-produced research project exploring the oral health behaviours and access to dental services of CECYP. Here, 'co-production' refers to the involvement of CYP in the planning or conduct of research with explicit roles in which they generate ideas, evidence and research outputs., Aim: To learn how to meaningfully involve vulnerable CYP in the co-production of health and social science research., Objectives: To identify: Different approaches to facilitating the engagement of vulnerable CYP in co-production of health and social science research; different activities carried out in such approaches, challenges to engaging vulnerable CYP in co-production of health and social science research and ways to overcome them and areas of best practice in relation to research co-production with vulnerable CYP., Search Strategy: A rapid review of peer-reviewed articles was conducted in six databases (MEDLINE, Embase, SocINDEX, CINAHL, PsycINFO and Web of Science) and grey literature to identify studies that engaged vulnerable CYP in co-approaches to health and social research., Main Results: Of 1394 documents identified in the search, 40 were included and analysed. A number of different approaches to co-production were used in the studies. The CYP was involved in a range of activities, chiefly the development of data collection tools, data collection and dissemination. Individual challenges for CYP and researchers, practical and institutional factors and ethical considerations impacted the success of co-production., Discussion and Conclusion: Co-production of health and social science with vulnerable CYP presents challenges to researchers and CYP calling for all to demonstrate reflexivity and awareness of biases, strengths and limitations. Used appropriately and well, co-production offers benefits to researchers and CYP and can contribute to research that reflects the needs of vulnerable CYP. Adherence to the key principles of inclusion, safeguarding, respect and well-being facilitates this approach., Patient and Public Contribution: Members of our patient and public involvement and stakeholder groups contributed to the interpretation of the review findings. This manuscript was written together with a young care leaver, Skye Boswell, who is one of the authors. She contributed to the preparation of the manuscript, reviewing the findings and their interpretation., (© 2024 The Authors. Health Expectations published by John Wiley & Sons Ltd.)

Data Sources and Search Strategy: Seven databases (MEDLINE, CINAHL, Embase, Scopus, ProQuest, Cochrane and Google Scholar) were searched up to the third week in June 2022. Keyword search terms were based on four key concepts: oral health, primary health, strategies, and integration., Study Selection: Peer-reviewed studies that evaluated any strategies to integrate oral health into primary care (e.g., guidelines, policies, workforce programmes) were included in the review. Eligibility was restricted to papers written in English language. Papers in non-primary care settings or which did not describe an evaluation were excluded. Two reviewers independently screened titles and abstracts and thereafter full texts. Disagreements were resolved by consulting a third reviewer., Data Extraction and Synthesis: Data were extracted by one reviewer; a second person verified accuracy. Covidence was used for data extraction. Two independent reviewers critically appraised the papers using the relevant tools (e.g. Critical Appraisal Skills Programme, Cochrane Collaboration, and STrengthening the Reporting of Observational studies in Epidemiology). PRISMA flow diagram was used to present the study selection process. Review findings were reported using a narrative synthesis approach. The Health System Building Blocks (HSBB) was used as a basis for structuring the results/discussion. Heterogeneity among the included studies was high and therefore no meta-analysis was conducted., Results: Forty-nine studies were included, of which two were RCTs. Most studies described oral healthcare delivered by non-dental primary care professionals within primary care services. Other settings included community, schools, and care homes. Outcomes of interest included: access to oral healthcare, knowledge/attitudes/perceptions, change in dental caries estimates. Almost all studies, except two studies which found no difference in the outcomes measured, favoured an integration strategy. Integration was achieved by enhancing competency (e.g. oral health promotion-trained educators), re-orientating responsibilities of health professionals at an organisation level and/or policy changes (e.g. expanded health insurance policy coverage to include oral health). Integration strategies enhanced access through improved referral pathways, documentation processes, operating efficiency, the number of health staff on hand, increased visits for oral health issues, higher fluoride varnish application rates for children, and more visits to dental health professionals., Conclusions: In this review, promoting an integrated approach for oral health was associated with improvements across a range of outcomes. Integrating oral health into primary care is complex but holds promise for reducing the burden of dental diseases. Identifying the best practice models of service integration requires further research and evaluation., (© 2024. The Author(s), under exclusive licence to British Dental Association.)

Background: Children and young people (CYP) in care experience poorer physical health and overall wellbeing in comparison to their peers. Despite this, relatively little is known about what their oral health needs and behaviours are. The aim of this scoping review was to provide a global perspective on the oral health status and behaviours of CYP in care and care leavers. It also aimed to synthesise interventions that have been trialled in this population to improve oral health., Methods: Five databases were searched, Ovid Embase, Ovid MEDLINE, CINAHL (EBSCOhost), SocINDEX (EBSCOhost) and Dentistry and Oral Sciences Source (EBSCOhost), alongside grey literature sources up to January 2023. Eligibility criteria were studies that (i) reported on children and adolescents aged 25 years or younger who are currently in formal/informal foster or residential care and care leavers, (ii) pertained to oral health profile, behaviours or oral health promotion interventions (iii) and were published in the English language. Thematic analysis was used to develop the domains for oral health behaviours and interventions., Results: Seventy-one papers were included. Most papers were published from very high or medium Human Development Index countries. CYP in care were found to experience high levels of decay, dental trauma, periodontal disease and poorer oral health-related quality of life. Oral health behaviours included limited oral health self-care behaviours and a lack of oral health-based knowledge. The trialled interventions involved oral health education, supervised brushing and treatment or preventative dental care., Conclusions: This scoping review reveals that CYP in care experience poorer oral health in comparison to their peers. They are also less likely to carry out oral health self-care behaviours. This review highlights a scarcity of interventions to improve the oral health of this population and a paucity of evidence surrounding the oral health needs of care leavers.

Aims: This scoping review aimed to explore three research questions: 1. What is the dental care access for children and young people (CYP) in care and care leavers? 2. What factors influence CYP in care and care leavers' access to dental care? 3. What pathways have been developed to improve access to oral health care for CYP in care and care leavers?, Methods: Five databases (Ovid MEDLINE, Ovid Embase, CINAHL, SocINDEX and Dentistry and Oral Sciences Source) and grey literature sources were systematically searched. Articles relating to CYP in care or care leavers aged 0-25 years old, published up to January 2023 were included. Abstracts, posters and publications not in the English language were excluded. The data relating to dental care access were analysed using thematic analysis., Results: The search identified 942 articles, of which 247 were excluded as duplicates. A review of the titles and abstracts yielded 149 studies. Thirty-eight were eligible for inclusion in the review: thirty-three peer-reviewed articles, one PhD thesis and four grey literature sources. All papers were published from very high or medium Human Development Index countries. The studies indicate that despite having higher treatment needs, CYP in care and care leavers experience greater difficulty in accessing dental services than those not care-experienced. Organisational, psycho-social and logistical factors influence their access to dental care. Their experience of dental care may be impacted by adverse childhood events. Pathways to dental care have been developed, but little is known of their impact on access. There are very few studies that include care leavers. The voices of care-experienced CYP are missing from dental access research., Conclusions: care-experienced CYP are disadvantaged in their access to dental care, and there are significant barriers to their treatment needs being met.

Objectives: Among people experiencing severe and multiple disadvantage (SMD), poor oral health is common and linked to smoking, substance use and high sugar intake. Studies have explored interventions addressing oral health and related behaviours; however, factors related to the implementation of these interventions remain unclear. This mixed-methods systematic review aimed to synthesise evidence on the implementation and sustainability of interventions to improve oral health and related health behaviours among adults experiencing SMD., Methods: Bibliographic databases (MEDLINE, EMBASE, PsycINFO, CINAHL, EBSCO, Scopus) and grey literature were searched from inception to February 2023. Studies meeting the inclusion criteria were screened and extracted independently by two researchers. Quality appraisal was undertaken, and results were synthesised using narrative and thematic analyses., Results: Seventeen papers were included (published between 1995 and 2022). Studies were mostly of moderate quality and included views from SMD groups and service providers. From the qualitative synthesis, most findings were related to aspects such as trust, resources and motivation levels of SMD groups and service providers. None of the studies reported on diet and none included repeated offending (one of the aspects of SMD). From the quantitative synthesis, no difference was observed in programme attendance between the interventions and usual care, although there was some indication of sustained improvements in participation in the intervention group., Conclusion: This review provides some evidence that trust, adequate resources and motivation levels are potentially important in implementing interventions to improve oral health and substance use among SMD groups. Further research is needed from high quality studies and focusing on diet in this population., Prospero Registration Number: CRD42020202416., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Introduction Substantial evidence has established associations between oral health and chronic diseases, mediated by common risk factors and inflammatory processes. Dental professionals are aptly positioned to screen for cardiovascular disease and diabetes high-risk indicators. This article presents a service evaluation of two dental practices delivering health screening in dental practice, and a call to action for the wider profession.Methods Following training, two general dental practices implemented a suite of health screens, including blood pressure, blood glucose, cholesterol, body mass index (BMI) and waist-to-height ratio. A service evaluation was undertaken to review and improve service provision.Results Most patients (78.4%) had blood pressure values above normal range. More than half (55.8%) were outside of the healthy range for BMI. Out-of-range results for cholesterol were observed in less than one-fifth (16.7%). High blood glucose values were observed for few patients (3.3%).Conclusion Dental professionals can be successfully trained to deliver health screening interventions. Out-of-range health screening results offer an opportunity to provide targeted health advice for both the oral and general health. Clear protocols and careful interpretation of screening tests are required to minimise patients' confusion. More robust alliances between dental and general medical care are recommended., (© 2023.

Background: Homelessness overlapping with substance use and offending is described as severe and multiple disadvantage (SMD). People experiencing SMD have poor oral health along with high levels of related behaviours such as substance use, smoking, and poor diet. Existing evidence largely describes the prevalence of oral health problems, substance use, and smoking in SMD groups. Little is known about interventions that can address these conditions in SMD groups. We aimed to review the effectiveness and cost-effectiveness of interventions on oral health and related health behaviours in adults experiencing SMD., Methods: For this systematic review, we searched bibliographic databases (MEDLINE, EMBASE, PsycINFO, CINAHL, EBSCO, Scopus) and grey literature for papers published from inception to February 2023. Two researchers independently reviewed the searches. Randomised controlled trials (RCTs), comparative studies and economic evaluations were included. Risk of bias was assessed. Population included adults experiencing SMD (including homelessness and substance use or repeat offending). Outcomes included oral health, and related behaviours (substance use, smoking, poor diet). Results were narratively synthesised. This review was registered with PROSPERO, CRD42020202416., Findings: The review included 38 studies (published between 1991 and 2023), with 34 reporting effectiveness. These studies comprised of 23 RCTs and 11 quasi-experimental studies conducted in the USA (25 studies), Canada (seven studies), France (one study), and Spain (one study). The interventions involving multiple components, such as housing services with substance use and mental health support, effectively reduced substance use in SMD groups; these were mostly individual-level interventions. However, these studies had short follow-up periods and high attrition rates. Only one study addressed oral health outcomes, none focused on diet, and three RCTs covered smoking, with one intervention showing smoking abstinence at 4 weeks. Some limited evidence suggested cost-effectiveness of substance use interventions., Interpretation: This review found that integrating services such as housing with other health-care services together could be effective in improving health behaviours, especially substance use among SMD groups. More evidence is needed specifically on oral health, smoking, and diet-related interventions. The generalisability of findings of this review is limited to high-income countries and shorter-term outcomes., Funding: National Institute for Health and Care Research (NIHR) Policy Research Programme., (Copyright © 2023 Elsevier Ltd.

Background: Social housing tenants are at greater risk of engaging in unhealthy behaviours than the general population. Housing association employees are in an ideal position to contribute positively to their tenants' health. 'New Home, New You' (NHNY) is a joint venture between a social housing association, a city council and a community healthcare provider in the South West of England. It was designed with the aim of improving the health and well-being of social housing tenants., Objectives: The aim of this retrospective evaluation was to establish whether social housing tenants were benefiting from this health-related behavioural intervention in terms of their mental well-being and health-related behaviours., Methods: This was a mixed-methods evaluation. The outcome evaluation was a secondary analysis of quantitative data collected during the NHNY project. The process of delivering and receiving the intervention was evaluated using qualitative, semi-structured interviews with housing officers and tenants who had participated in the programme. The development of the intervention was evaluated through a focus group and additional semistructured interviews with key stakeholders. Quantitative data were analysed using the Statistical Package for the Social Sciences. Qualitative interviews were analysed using thematic analysis., Results: Six key stakeholders and a total of seven housing officers from several teams and seven tenants were interviewed. Of the 1016 tenants who were invited to participate in NHNY, 226 enroled in the programme. For participating tenants, the scope for health-related behaviour change was greatest in relation to eating and smoking. Small positive statistically significant changes in mental health were found between the 6- and 12-month mean score and between the baseline and the 12-month score., Conclusions: The findings indicate that NHNY may have been beneficial for some participating tenants. Housing officers can have a significant role in promoting health messages and embedding behaviour change among their tenants. Although the programme was implemented as a service improvement rather than a controlled trial and focused on a particular intervention and geographical area, other housing associations may find this evaluation useful for considering whether to adopt some of the principles applied in NHNY in other settings., Patient or Public Contribution: A social housing tenant representative provided input on the methodology and methods used to evaluate NHNY, as well as the information sheet., (© 2023 The Authors.

Introduction UK dentists experience high levels of stress, anxiety and burnout. Poor mental health can lead practitioners to exit the profession, contributing to workforce and service loss. Therefore, there is a need to focus on interventions to protect the mental health and wellbeing of dental teams. Three levels of intervention can be deployed in the workplace to support mental health and wellbeing: primary prevention, secondary prevention, and tertiary prevention.Aim The aim of this systematic review was to identify evidence on interventions used to prevent, improve or tackle mental health issues among dental team members and dental profession students in countries of very high development.Methods This systematic review was conducted according to a predefined protocol and reported according to PRISMA guidelines. The MEDLINE, Embase CINAHL, DOSS, Scopus, and PsycINFO databases were searched. Prospective empirical studies were considered for inclusion. The Effective Public Health Practice Project Quality Assessment Tool (EPHPP) was used to assess the methodological quality of the included studies. The identified interventions were categorised according to level of prevention.Results The search yielded 12,919 results. Eight studies met the inclusion criteria. All of the studies concerned dentists or dental students. There were no studies for other groups of dental professionals. No primary prevention-level studies were identified. Secondary prevention-level studies (n = 4) included various psychoeducational interventions aiming to raise awareness and improve coping skills and led to significant improvements in stress levels and burnout of dentists and dental students. Tertiary prevention-level studies (n = 4) mainly employed counselling which was shown to be beneficial for dentists and students experiencing psychological ill-health.Conclusions Mental wellbeing awareness should be put at the centre of dental education and the workplace. Leadership and innovation are required to design primary-level interventions which can be implemented in the UK dental sector, with its distinct organisational and service characteristics., (© 2022.

Aims: To investigate the scope of practice of nurse-led services for people experiencing homelessness, and the influence on access to healthcare., Design: A scoping review., Data Sources: On 20 November 2020, the following databases were searched: CINAHL, Embase, MEDLINE, PubMed and Scopus., Review Methods: Included studies focused on people experiencing homelessness aged 18 years and over, nurse-led services in any setting and described the nursing scope of practice. Studies were peer-reviewed primary research, published in English from the year 2000. Three authors performed quality appraisals using the mixed methods assessment tool. Results were synthesized and discussed narratively and reported according to the PRISMA-ScR 2020 Statement., Results: Nineteen studies were included from the United States (n = 9), Australia (n = 4), United Kingdom (n = 4) and Canada (n = 2). The total participant sample size was n = 6303. Studies focused on registered nurses (n = 10), nurse practitioners (n = 5) or both (n = 4), in outpatient or community settings. The nursing scope of practice was broad and covered a range of skills, knowledge and attributes. Key skills identified include assessment and procedural skills, client support and health education. Key attributes were a trauma-informed approach and building trust through communication. Important knowledge included understanding the impact of homelessness, knowledge of available services and the capacity to undertake holistic assessments. Findings suggest that nurse-led care facilitated access to healthcare through building trust and supporting clients to access services., Conclusion: Optimized nursing scope of practice can facilitate access to healthcare for people experiencing homelessness. Key factors in enabling this include autonomy in nursing practice, organizational support and education., Impact: The broad range of skills, knowledge and attributes reported provide a foundation from which to design an educational framework to optimize the nursing scope of practice, thereby increasing access to healthcare for people experiencing homelessness., (© 2022 The Authors.

Background: Aerosols and spatter are generated in a dental clinic during aerosol-generating procedures (AGPs) that use high-speed hand pieces. Dental healthcare providers can be at increased risk of transmission of diseases such as tuberculosis, measles and severe acute respiratory syndrome (SARS) through droplets on mucosae, inhalation of aerosols or through fomites on mucosae, which harbour micro-organisms. There are ways to mitigate and contain spatter and aerosols that may, in turn, reduce any risk of disease transmission. In addition to personal protective equipment (PPE) and aerosol-reducing devices such as high-volume suction, it has been hypothesised that the use of mouth rinse by patients before dental procedures could reduce the microbial load of aerosols that are generated during dental AGPs., Objectives: To assess the effects of preprocedural mouth rinses used in dental clinics to minimise incidence of infection in dental healthcare providers and reduce or neutralise contamination in aerosols., Search Methods: We used standard, extensive Cochrane search methods. The latest search date was 4 February 2022., Selection Criteria: We included randomised controlled trials and excluded laboratory-based studies. Study participants were dental patients undergoing AGPs. Studies compared any preprocedural mouth rinse used to reduce contaminated aerosols versus placebo, no mouth rinse or another mouth rinse. Our primary outcome was incidence of infection of dental healthcare providers and secondary outcomes were reduction in the level of contamination of the dental operatory environment, cost, change in mouth microbiota, adverse events, and acceptability and feasibility of the intervention., Data Collection and Analysis: Two review authors screened search results, extracted data from included studies, assessed the risk of bias in the studies and judged the certainty of the available evidence. We used mean differences (MDs) and 95% confidence intervals (CIs) as the effect estimate for continuous outcomes, and random-effects meta-analysis to combine data  MAIN RESULTS:  We included 17 studies with 830 participants aged 18 to 70 years. We judged three trials at high risk of bias, two at low risk and 12 at unclear risk of bias.  None of the studies measured our primary outcome of the incidence of infection in dental healthcare providers.  The primary outcome in the studies was reduction in the level of bacterial contamination measured in colony-forming units (CFUs) at distances of less than 2 m (intended to capture larger droplets) and 2 m or more (to capture droplet nuclei from aerosols arising from the participant's oral cavity). It is unclear what size of CFU reduction represents a clinically significant amount. There is low- to very low-certainty evidence that chlorhexidine (CHX) may reduce bacterial contamination, as measured by CFUs, compared with no rinsing or rinsing with water. There were similar results when comparing cetylpyridinium chloride (CPC) with no rinsing and when comparing CPC, essential oils/herbal mouthwashes or boric acid with water. There is very low-certainty evidence that tempered mouth rinses may provide a greater reduction in CFUs than cold mouth rinses. There is low-certainty evidence that CHX may reduce CFUs more than essential oils/herbal mouthwashes. The evidence for other head-to-head comparisons was limited and inconsistent.  The studies did not provide any information on costs, change in micro-organisms in the patient's mouth or adverse events such as temporary discolouration, altered taste, allergic reaction or hypersensitivity. The studies did not assess acceptability of the intervention to patients or feasibility of implementation for dentists.  AUTHORS' CONCLUSIONS: None of the included studies measured the incidence of infection among dental healthcare providers. The studies measured only reduction in level of bacterial contamination in aerosols. None of the studies evaluated viral or fungal contamination. We have only low to very low certainty for all findings. We are unable to draw conclusions regarding whether there is a role for preprocedural mouth rinses in reducing infection risk or the possible superiority of one preprocedural rinse over another. Studies are needed that measure the effect of rinses on infectious disease risk among dental healthcare providers and on contaminated aerosols at larger distances with standardised outcome measurement., (Copyright © 2022 The Cochrane Collaboration.

Background: Autistic children and young people (CYP) experience oral health (OH) inequalities. They are at high risk of dental disease and show significant levels of unmet need in relation to OH and access to dental care., Aim: This study aimed to gather evidence on the factors that influence OH behaviours, access to and delivery of dental care for autistic CYP., Design: This was a mixed-methods narrative systematic review., Data Sources: Embase, Web of Science, Dentistry & Oral Sciences Source, MEDLINE, Psychinfo, Scopus, CINAHL, SocINDEX and grey literature were the data sources for this study., Review Methods: A systematic search was conducted for qualitative, quantitative and mixed-methods research studies from countries with a High Development Index that related to OH behaviours, access to and delivery of dental care for autistic CYP. Results were analysed using narrative synthesis., Results: From 59 eligible studies, 9 themes were generated: (1) affordability and accessibility; (2) autism-related factors and cognitive or motor skill differences; (3) the dental environment; (4) managing CYP's behaviour; (5) responding and adapting to the needs of the autistic CYP and their parent/carer; (6) attitude of dental health professionals (DHPs) towards autistic CYP and their parents/carers; (7) knowledge of how to care for and support CYP's OH; (8) empowerment of parents/carers and collaboration with DHPs; and (9) communication and building rapport., Conclusion: The adoption of healthy OH behaviours and access to dental care by autistic CYP is impacted by a range of factors including those intrinsically related to a diagnosis of autism, for example, communication and those often associated with autism, for example, sensory sensitivities. Access to better OH and dental care can be facilitated by responding to the individual needs of autistic CYP through accommodation, education and adaptation. This necessitates greater awareness and knowledge of autism amongst DHPs and the provision of appropriate services. More methodologically robust intervention studies are needed to identify effective ways to support autistic CYP in achieving good OH and access to dental care., Patient and Public Contribution: The review protocol was developed with members of the project patient and public involvement group who provided the autistic voice, contributing to the interpretation of the review findings and writing of the manuscript., (© 2022 The Authors.

Introduction Poor oral health and barriers to accessing dental services are common among people experiencing social exclusion. This population experience a disproportionate and inequitable burden of oral disease. A small number of dental services have published models of care that target this population, but no national surveys have been conducted.Aims This study aims to identify what types of services are providing dental and oral healthcare for people experiencing social exclusion in England and the models of delivery adopted by these services.Methods A snowballing sampling strategy was used to identify services that provide targeted for adults experiencing social exclusion. The study used a survey to collect data about the location, service models and barriers and enablers of these services.Results In total, 74 responses from different services met the inclusion criteria for the study. Seventy one were included in the mapping exercise and 53 provided free-text comments that contributed to an understanding of barriers and enablers of services.Discussion Most services operated to meet the needs of the mainstream population and described inflexibilities in their service design models as barriers to providing care for socially excluded groups.Conclusion Limitations of current models of service delivery create frustrations for providers and people experiencing social exclusion. Creative commissioning and organisational flexibility are key to facilitating adaptable services., (© 2022. The Author(s), under exclusive licence to the British Dental Association.)

Aims To investigate factors influencing oral health behaviours and access to dental services for asylum seekers and refugees (ASRs).Methods A qualitative research study using purposeful sampling was undertaken in South West England. Online semi-structured interviews with stakeholders working with or supporting ASRs were analysed through reflexive thematic analysis.Results Twelve participants providing support to ASRs in various capacities participated. Two interviewees had lived experience of forced displacement and the UK asylum process. Key themes into what hinders ASRs' oral health care were: prioritising safety and survival; variations in cultural norms and practice; lack of knowledge about dental care; financial hardship and affordability of care; a gulf of understanding of what dental care would be like and experiences of it; and structures of dental services that leave vulnerable groups behind. Opportunities for improving oral health care were: accessible oral health education; partnership working and creating supportive environments; translation; providing culturally sensitive and person-centred care; and incorporating ASRs' views into service design.Conclusions Several factors affect to what extent ASRs can and are willing to engage with oral health care. Co-developing accessible and relevant prevention programmes and ensuring equitable access to dental services for ASRs is important. Future research should explore ASRs' views and experiences of dental care and explore informed suggestions on how to optimise oral health promotion and provision of care., (© 2022.

Shortly after the declaration of the COVID-19 pandemic, governments around the world were urged to leave no population behind. Following a COVID-19 risk evaluation in a refugee and asylum seekers reception center, in September 2020, we considered the priorities of managing COVID-19 in these settings. We encourage actions on the following four fronts to reduce the COVID-19-associated burden among these vulnerable populations based on our interviews, observations, and recommendations: (i) decongestion, (ii) facilitated testing, (iii) screening for symptoms, and (iv) targeted public health and risk communication., Competing Interests: Declaration of Competing Interest The authors declared no conflicts of interest., (Copyright © 2022.

Background: People experiencing homelessness have an increased risk of hepatitis C virus (HCV) infection, with rates higher than the general population. However, their access to HCV diagnosis is limited and treatment uptake is low., Objectives: To identify and describe the barriers and facilitators for HCV screening and treatment for adults with lived experience of homelessness in highly developed countries., Methods: Bibliographic databases (Embase, MEDLINE, CINAHL and SocINDEX) and grey literature (Google, EThOS, the Health Foundation, Social Care Online, the World Health Organisation, Shelter, Crisis and Pathway) were searched. Two reviewers independently screened and appraised all studies. The Critical Appraisal Skills Programme tool and the Joanna Briggs Institute checklist were used. The analysis involved a three-stage process: coding, theme generation and theme mapping under Penchansky and Thomas's modified access model., Results: Twelve papers/reports were included in the review. Several interacting factors influence access of people with lived experience of homelessness to HCV testing and treatment. Some mirror those identified for the general population. The precarious conditions associated with the lived experience of homelessness along with the rigidity of hospital settings and lack of awareness emerged as dominant barriers. Flexibility, outreach, effective communication, tailoring and integration of services were found to be important facilitators. Evidence from Black, Asian and minority ethnic groups is limited., Conclusions: People experiencing homelessness face multiple barriers in accessing and completing HCV treatment, relating to both their lived experience and characteristics of health systems. Although some barriers are readily amenable to change, others are more difficult to modify. The facilitators identified could inform future targeted measures to improve HCV diagnosis and treatment for people experiencing homelessness. Research is warranted into successful models to promote screening, diagnosis and treatment., Patient or Public Contribution: Our team includes a peer advocate, a hepatology nurse and a community volunteer, all with significant experience in promoting and engaging in HCV care and outreach for people experiencing homelessness. They contributed to the protocol, interpretation and reporting of the review findings., (© 2021 The Authors. Health Expectations published by John Wiley & Sons Ltd.)

Dental healthcare students at the Peninsula Dental School, University of Plymouth, UK undertake community engagement projects as a core part of their undergraduate curriculum. Students work with their peers to develop a student-led, evidence-based project working with target groups in the local community to address oral health needs. The aim of the programme is to further the students' understanding of health inequalities and the health needs of different groups in the community, while developing skills that will help them deliver holistic dental care as part of their future professional practice. This report highlights our model of education delivery in collaboration with the community, the student-learning outcomes and discusses some of the benefits of this approach including examples of projects that have benefitted the community. We highlight the further work needed to evaluate the longer-term impacts on students of undertaking social accountability programmes.

Autistic children and adolescents are at high risk of dental disease and experience oral health inequalities. They consistently show high levels of unmet needs in relation to their oral health and access to dental care. There are no systematic reviews that bring together the evidence on the factors that influence oral hygiene behaviours, and access to and provision of dental care for autistic children and adolescents. A systematic search will be carried out in eight international databases and in grey literature of qualitative, quantitative and mixed method research studies from countries with a High Development Index which relate to oral health behaviours, and access to and provision of dental care. Only studies where participants are autistic children and adolescents aged 19 years or under, parents/guardians/caregivers, support staff, or oral health care providers will be included. Quantitative and qualitative data will be synthesized together through data transformation using a convergent integrated approach. Thematic synthesis will be used to carry out an inductive analysis of the data. The findings from the systematic review which this protocol generates will be used in the development of an appropriate local clinic care pathway for autistic children/adolescents and to inform national policies and practices.

The number of individuals in England experiencing homelessness, substance use, and involvement with the criminal justice system is increasing. These issues, referred to as severe and multiple disadvantage (SMD), are often interlinked and co-occur. Health inequalities, particularly poor oral health, persist for those facing these inter-related issues and are closely linked with high levels of substance use, smoking, and poor diet. However, evidence for interventions that can improve these health outcomes for those experiencing these issues is limited. This paper outlines the design of a qualitative study which aims to explore the perspectives of stakeholders to understand what interventions can help to support SMD groups with their oral health and related health behaviours (i.e., substance use, smoking, diet). Interviews and focus groups will be undertaken with stakeholders comprising two groups: (1) individuals with experience of SMD, and (2) service providers (staff and volunteers), policy makers, and commissioners who support such individuals. Public involvement and engagement is central to the project. For example, stakeholders and research partners in policy and practice and people with lived experience of SMD will provide input at all stages of this study. Findings from the study will inform an 'evidence for practice' briefing outlining recommendations for policy. Dissemination will occur through presentations to a range of practice, policy and academic beneficiaries, and through peer-reviewed publications.

Increasing numbers of people in England experience homelessness, substance use, and repeated offending (known as 'severe and multiple disadvantage'; SMD). Populations experiencing SMD often have extremely poor oral health, which is closely inter-linked with high levels of substance use, smoking, and poor diet. This study aims to undertake an evidence synthesis to identify the effectiveness, resource requirements, and factors influencing the implementation and acceptability of oral health and related health behaviour interventions in adults experiencing SMD. Two systematic reviews will be conducted using mixed-methods. Review 1 will investigate the effectiveness and resource implications of oral health and related health behaviours (substance use, smoking, diet) interventions; Review 2 will investigate factors influencing the implementation of such interventions. The population includes adults (≥18 years) experiencing SMD. Standard review methods in terms of searches, screening, data extraction, and quality appraisal will be conducted. Narrative syntheses will be conducted. If feasible, a meta-analysis will be conducted for Review 1 and a thematic synthesis for Review 2. Evidence from the two reviews will then be synthesised together. Input from people with experience of SMD will be sought throughout to inform the reviews. An initial logic model will be iteratively refined during the review.

The sexual health needs of young people experiencing homelessness in the UK have not been researched adequately. This study aimed to examine knowledge and attitudes around sexual health and contraceptive use amongst this vulnerable group to develop suitable models of care in the community. A qualitative ethnographic case-study following Burawoy's extended case method was used. Semi-structured interviews with 29 young people experiencing homelessness and five key workers in London hostels were carried out together with ethnographic observations and analysis of documentary evidence. Thematic analysis was undertaken. Demographic data were collected. Three significant themes were identified: risks and extreme vulnerability, relationships and communication difficulties and emergence of a culture of homelessness. Young people experiencing homelessness require specialist delivery of sexual health care in safe surroundings. Initial care should focus on assessment of basic needs and current state of being. Establishing trusting relationships and considering ongoing vulnerability, can help promote meaningful and personalised sexual healthcare both at policy and practice level.

Introduction While routine dentistry was suspended during the COVID-19 pandemic, Urgent Dental Care centres (UDCs) were established to support patients with urgent dental needs.Aim The study aimed to provide insights and recommendations on future dental reform based on the perspectives of frontline staff delivering dental care in UDCs.Method A qualitative research study using a phenomenological approach. A hybrid approach that incorporated both a deductive and an inductive approach to analysis was adopted.Results The sample included 29 dentists and nine dental nurses providing care at UDCs in England during the pandemic. The following predominant themes were identified: patient care and access, practice viability, workforce sustainability, identity of dentistry and contract reform.Conclusions The pandemic has highlighted the desire from the dental profession for urgent reform of the current NHS dental contract in England. This was directed towards a more resilient, responsive and equitable dental service that is better prepared for current and future challenges., (© 2021.

Introduction Following the World Health Organisation declaration of COVID-19 as a global pandemic, routine dental care in the UK ceased, and Urgent Dental Care centres (UDCs) were established to offer remote and face-to-face urgent dental treatment for those in need.Aim To explore perceptions and psychosocial experiences of frontline staff providing care at UDCs in England during COVID-19.Method A qualitative research study using a phenomenological approach. Semi-structured interviews were conducted remotely. Using line-by-line coding, data were analysed using a hybrid approach that incorporated both a deductive, theoretical process and an inductive, data-driven process.Results Participants included 29 dentists and nine dental nurses from UDCs across England. Twelve themes were identified and grouped into positive and negative experiences. Positive experiences were: role fulfilment and having a sense of purpose; team unity and collective coping strategies; and strategic teamwork and preparedness for effective organisation of care. Negative experiences included: feeling undervalued and frustrated due to fragmented guidance and communication; sense of unfairness generated by relational challenges; patient demand outstripping UDC capacity; complex decision-making; uncertainty over safety; suffocating PPE hindering effective communication; ineffective communication channels across healthcare sectors; lack of commitment to remote video consultations; and variable referral quality.Conclusions Participants reported experiencing a number of emotional challenges that appeared to be exacerbated by an unsupportive environment, often due to lack of leadership. However, positive experiences and coping strategies were also identified. Collective and sustained efforts at system level to improve the resilience and mental wellbeing of the current and future dental workforce and integration of dentistry into wider healthcare infrastructures are needed., (© 2021.

Introduction: People who experience homelessness face disproportionately poor reproductive health and adverse pregnancy outcomes, including but not limited to unintended pregnancy, abortion, low birth weight and preterm birth, as well as a higher risk of sexually transmitted infections (STIs). Precarious living conditions are known to contribute to poor uptake and engagement with sexual and reproductive healthcare (SRH) for this population., Aim: To identify and understand the perceived barriers and facilitators for accessing and utilising SRH for people who experience homelessness from their perspective, and the perspective of support staff/volunteers and healthcare professionals., Methods: Electronic databases and online sources were searched. Two reviewers independently carried out the screening, data extraction, critical appraisal, data synthesis and thematic analysis of findings., Results: Following deduplication and screening, 23 papers/reports were considered eligible for the review. Barriers for people experiencing homelessness to accessing and utilising SRH were identified within the themes of complexity, feelings and knowledge (ie, individual-level factors), as well as patient/provider interaction and healthcare system (ie, organisational factors). Facilitators were identified within all of the above themes except for complexity., Conclusions: Both population characteristics and attributes of the healthcare system influence access and utilisation of SRH by people experiencing homelessness. Given the complexity of living conditions associated with homelessness, greater efforts to improve access should be placed on healthcare systems and aspects of care delivery. This systematic review highlights current gaps in the literature and provides recommendations for enhancing future research and practice to meet the needs of this vulnerable group more effectively., Competing Interests: Competing interests: JS is a member of the Faculty of Sexual and Reproductive Healthcare (FSRH) Sexual and Reproductive Health Clinical Studies Group (SRH CSG)., (© Author(s) (or their employer(s)) 2021.

Data sources Databases searched included PsycINFO, PubMed, SciELO, Scopus and Web of Science.Study selection Cross-sectional, longitudinal and retrospective studies that compared caries, periodontal disease or tooth loss in people who use drugs as compared to those who do not. Studies that included psychiatric populations and alcohol or tobacco users were not included in the review. Qualitative studies, in vitro investigations, animal studies, reviews, case reports and series, letters to editor and conference abstracts were also excluded. The authors included only English studies published before 1 July 2019. Two independent reviewers screened the papers on title and abstract and then full text. In case of disagreements, these were discussed between the two reviewers and a third one was consulted if needed.Data extraction and synthesis Two reviewers extracted the data and contacted the primary authors for necessary clarifications, if needed. The unweighted kappa was applied to examine inter-examiner agreement. The Joanna Briggs Institute Critical Appraisal Checklist for observational studies was used to critically appraise the studies. The study selection results were presented through a flowchart. For the meta-analysis, the authors considered adjusted data. In some cases, crude estimates were used. Heterogeneity was estimated using the I2 statistic. The 'meta' package was used for the meta-analysis.Results Ten studies were included in the meta-analysis. Drug use was associated with higher risk of periodontal disease (OR 1.44; 95% CI 0.8-2.6) and higher DMFT index (OR 4.11; 95% CI 2.07-8.15).Conclusions The review showed high risk of periodontal disease and caries among people who use drugs. The authors concluded that this association may be explained by irregular tooth brushing and long history of drug use. It is important to develop programmes that aim to improve oral hygiene practices among people who use drugs.

Data sources Databases searched included Web of Science, PubMed and Scopus.Study selection Cross-sectional studies that estimated dental healthcare needs and unmet dental needs in young people, aged 10-19 years were considered for inclusion. No limitations in terms of year of publication, language, location of the study, gender and race of the participants, or the type of dental health needs and unmet needs were applied. The papers were screened on title and abstract, and then on full text by two reviewers. Any disagreements were resolved through discussion and consultation with a third reviewer.Data extraction and synthesis Data were extracted by three reviewers. Critical appraisal was conducted by two reviewers using the Joanna Briggs Institute critical appraisal checklist. A PRISMA flowchart was used to present the study selection results. Summary measures on the prevalence of dental health needs and unmet needs were calculated. For the meta-analysis, the inverse variance method was used to obtain pooled summary measures.Results Fifty-seven studies were included in the review. The overall prevalence of dental healthcare needs was 49% (95% CI: 42-56) across all types of dental care. The highest prevalence was that for periodontal treatment needs (71%; 95% CI: 46-96 as reported in four studies), followed by that of general treatment needs (59.0%; 95% CI: 42-75 as reported in 12 studies), orthodontic treatment (46%; 95% CI: 38-53 as reported in 32 studies) and lastly that of malocclusion treatment needs (39%; 95% CI: 28-50 as reported in nine studies). The pooled prevalence of unmet dental needs as reported in nine studies was 34% (95% CI: 27-40) with the highest prevalence found in Southeast Asia (72.3%; 95% CI: 70.1-74.5) and the lowest in Europe (11.8%; 95% CI: 3.4-20.3).Conclusions The results of this review showed that the prevalence of dental healthcare needs was higher in America and Europe while unmet needs were more prevalent in Southeast Asia and Africa. The former could partly be explained by the lower number and sample sizes of studies conducted in developing countries.Commentary.

Data sources PubMed, Medline, Embase, CINAHL, Cochrane Library database and ProQuest databases were searched.Study selection Observational and non-randomised studies in English language were considered for inclusion. Two reviewers independently selected the relevant studies. Any disagreement was resolved by discussion with a third reviewer. The outcome of interest for this review was oral health-related quality of life (OHRQoL) in patients with Alzheimer's disease.Data extraction and synthesis Data extraction was conducted independently by two reviewers. Critical appraisal was conducted by two reviewers using the Joanna Briggs Institute 'Meta-Analysis of Statistics Assessment and Review Instrument'.Results Six studies were included in the review, of which five were cross-sectional and one was a non-randomised controlled trial. OHRQoL was measured by the Oral Health Impact Profile (OHIP) in one study and the Geriatric Oral Health Assessment Index (GOHAI) in the other five included studies. All six studies were judged as methodologically strong. When the results of four studies which used the GOHAI were pooled together in a meta-analysis, no statistically significant differences in the GOHAI scores between patients with Alzheimer's disease and controls were found (SMD = 0.09; 95%CI: -0.66 to 0.85).Conclusions The results of this review showed no significant difference in OHRQoL between patients with Alzheimer's disease and healthy controls.

Background: Dental diseases are prevalent among asylum seekers and refugees (ASRs). Despite significant treatment needs, access to dental care in host countries is often limited. The aim of this systematic review was to identify the barriers and enablers to dental care access for ASRs in host countries of very high development., Methods: Five health and social care databases and eight grey literature sources of information were searched. The Critical Appraisal Skills Programme tool was used to critically appraise included studies. Thematic analysis was undertaken to identify common themes. These were then deductively organised according to Penchansky and Thomas's modified access model. All review stages were conducted by two independent reviewers., Results: Nine papers were included in the review. ASRs encounter significant challenges to accessing dental care in their host countries. These include affordability, communication difficulties, insufficient interpretation, limited knowledge of the healthcare systems and healthcare rights, and negative encounters with healthcare teams. The views and experiences of dental care teams providing care to ASRs were explored in only one study., Conclusions: Both population and healthcare characteristics influence access to dental care for ASRs. Affordability, awareness and accommodation are most frequently described as barriers to dental access for this population. The diverse needs of this population need to be recognised by policy makers, commissioners and practitioners alike. Cultural competence needs to be incorporated into dental services and any interventions to improve access to dental care for this population.

Background: Many dental procedures produce aerosols (droplets, droplet nuclei and splatter) that harbour various pathogenic micro-organisms and may pose a risk for the spread of infections between dentist and patient. The COVID-19 pandemic has led to greater concern about this risk., Objectives: To assess the effectiveness of methods used during dental treatment procedures to minimize aerosol production and reduce or neutralize contamination in aerosols., Search Methods: Cochrane Oral Health's Information Specialist searched the following databases on 17 September 2020: Cochrane Oral Health's Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL) (in the Cochrane Library, 2020, Issue 8), MEDLINE Ovid (from 1946); Embase Ovid (from 1980); the WHO COVID-19 Global literature on coronavirus disease; the US National Institutes of Health Trials Registry (ClinicalTrials.gov); and the Cochrane COVID-19 Study Register. We placed no restrictions on the language or date of publication., Selection Criteria: We included randomized controlled trials (RCTs) and controlled clinical trials (CCTs) on aerosol-generating procedures (AGPs) performed by dental healthcare providers that evaluated methods to reduce contaminated aerosols in dental clinics (excluding preprocedural mouthrinses). The primary outcomes were incidence of infection in dental staff or patients, and reduction in volume and level of contaminated aerosols in the operative environment. The secondary outcomes were cost, accessibility and feasibility., Data Collection and Analysis: Two review authors screened search results, extracted data from the included studies, assessed the risk of bias in the studies, and judged the certainty of the available evidence. We used mean differences (MDs) and 95% confidence intervals (CIs) as the effect estimate for continuous outcomes, and random-effects meta-analysis to combine data. We assessed heterogeneity., Main Results: We included 16 studies with 425 participants aged 5 to 69 years. Eight studies had high risk of bias; eight had unclear risk of bias. No studies measured infection. All studies measured bacterial contamination using the surrogate outcome of colony-forming units (CFU). Two studies measured contamination per volume of air sampled at different distances from the patient's mouth, and 14 studies sampled particles on agar plates at specific distances from the patient's mouth. The results presented below should be interpreted with caution as the evidence is very low certainty due to heterogeneity, risk of bias, small sample sizes and wide confidence intervals. Moreover, we do not know the 'minimal clinically important difference' in CFU. High-volume evacuator Use of a high-volume evacuator (HVE) may reduce bacterial contamination in aerosols less than one foot (~ 30 cm) from a patient's mouth (MD -47.41, 95% CI -92.76 to -2.06; 3 RCTs, 122 participants (two studies had split-mouth design); very high heterogeneity I² = 95%), but not at longer distances (MD -1.00, -2.56 to 0.56; 1 RCT, 80 participants). One split-mouth RCT (six participants) found that HVE may not be more effective than conventional dental suction (saliva ejector or low-volume evacuator) at 40 cm (MD CFU -2.30, 95% CI -5.32 to 0.72) or 150 cm (MD -2.20, 95% CI -14.01 to 9.61). Dental isolation combination system One RCT (50 participants) found that there may be no difference in CFU between a combination system (Isolite) and a saliva ejector (low-volume evacuator) during AGPs (MD -0.31, 95% CI -0.82 to 0.20) or after AGPs (MD -0.35, -0.99 to 0.29). However, an 'n of 1' design study showed that the combination system may reduce CFU compared with rubber dam plus HVE (MD -125.20, 95% CI -174.02 to -76.38) or HVE (MD -109.30, 95% CI -153.01 to -65.59). Rubber dam One split-mouth RCT (10 participants) receiving dental treatment, found that there may be a reduction in CFU with rubber dam at one-metre (MD -16.20, 95% CI -19.36 to -13.04) and two-metre distance (MD -11.70, 95% CI -15.82 to -7.58). One RCT of 47 dental students found use of rubber dam may make no difference in CFU at the forehead (MD 0.98, 95% CI -0.73 to 2.70) and occipital region of the operator (MD 0.77, 95% CI -0.46 to 2.00). One split-mouth RCT (21 participants) found that rubber dam plus HVE may reduce CFU more than cotton roll plus HVE on the patient's chest (MD -251.00, 95% CI -267.95 to -234.05) and dental unit light (MD -12.70, 95% CI -12.85 to -12.55). Air cleaning systems One split-mouth CCT (two participants) used a local stand-alone air cleaning system (ACS), which may reduce aerosol contamination during cavity preparation (MD -66.70 CFU, 95% CI -120.15 to -13.25 per cubic metre) or ultrasonic scaling (MD -32.40, 95% CI - 51.55 to -13.25). Another CCT (50 participants) found that laminar flow in the dental clinic combined with a HEPA filter may reduce contamination approximately 76 cm from the floor (MD -483.56 CFU, 95% CI -550.02 to -417.10 per cubic feet per minute per patient) and 20 cm to 30 cm from the patient's mouth (MD -319.14 CFU, 95% CI - 385.60 to -252.68). Disinfectants ‒ antimicrobial coolants Two RCTs evaluated use of antimicrobial coolants during ultrasonic scaling. Compared with distilled water, coolant containing chlorhexidine (CHX), cinnamon extract coolant or povidone iodine may reduce CFU: CHX (MD -124.00, 95% CI -135.78 to -112.22; 20 participants), povidone iodine (MD -656.45, 95% CI -672.74 to -640.16; 40 participants), cinnamon (MD -644.55, 95% CI -668.70 to -620.40; 40 participants). CHX coolant may reduce CFU more than povidone iodine (MD -59.30, 95% CI -64.16 to -54.44; 20 participants), but not more than cinnamon extract (MD -11.90, 95% CI -35.88 to 12.08; 40 participants)., Authors' Conclusions: We found no studies that evaluated disease transmission via aerosols in a dental setting; and no evidence about viral contamination in aerosols. All of the included studies measured bacterial contamination using colony-forming units. There appeared to be some benefit from the interventions evaluated but the available evidence is very low certainty so we are unable to draw reliable conclusions. We did not find any studies on methods such as ventilation, ionization, ozonisation, UV light and fogging. Studies are needed that measure contamination in aerosols, size distribution of aerosols and infection transmission risk for respiratory diseases such as COVID-19 in dental patients and staff., (Copyright © 2020 The Cochrane Collaboration.

Background: People who experience homelessness have higher dental treatment needs compared to the general population. However, their utilization of dental services and levels of treatment completion are low. Peninsula Dental Social Enterprise, a not-for-profit organization in the United Kingdom, established a community dental clinic to improve access to dental care for this population., Objectives: To evaluate the impact and acceptability of the community dental service for patients and examine the barriers and enablers to using and providing the service., Methods: The evaluation included a retrospective assessment of anonymous patient data and thematic analysis of semi-structured interviews with patients, support staff and service providers. The interviews were thematically analysed. A cost analysis of the dental service was also conducted., Results: By 18 February 2020, 89 patients had attended the clinic. These included 62 males (70%) and 27 females (30%), aged 38.43 years on average (SD ± 11.07). Of these, 42 (47%) patients have completed their treatment, 23 (26%) are in active treatment and 24 (27%) left treatment. In total, 684 appointments (541.5 hours clinical time) were given. Of these, 82% (562) of appointments were attended (452.5 hours clinical time). The 22 interviews that were conducted identified flexibility, close collaboration with support services and health-care team attitudes as key factors influencing service utilization and continuity of care., Conclusions: This study provides details of a highly acceptable and accessible dental care model for people experiencing homelessness, with recommendations at research, practice and commissioning levels., (© 2020 The Authors Health Expectations published by John Wiley & Sons Ltd.)

Objectives The present study aimed to identify strategies to improve oral health behaviours as well as access to and provision of dental care for people experiencing homelessness.Method We conducted focus groups with people living in a residential homeless centre and semi-structured interviews with other stakeholders working with or supporting people experiencing homelessness. Following an inductive approach, thematic analysis was used to synthesise the findings on NVivo software.Results Participants included 11 British males experiencing homelessness and 12 other stakeholders from various professional backgrounds. Themes identified included: awareness and empowerment; supportive environment and dental health system; flexible and holistic care; outreach and community engagement; collaboration with other health and social services; and effective communication.Conclusions Efforts to improve oral health among people experiencing homelessness via improved oral health habits and engagement with services need to be directed at both the recipients of care and the healthcare teams. Well-powered empirical studies are needed to evaluate whether the strategies identified can improve engagement and care provision for this population., (© 2020. British Dental Association.)

Data sources Databases searched included the International Database for Medical Research MEDLINE/Pubmed, ISI Web of Science, Scopus, Scientific Electronic Library Online (SciELO), and Latin American and Caribbean Health Sciences (LILACS).Study selection Studies of observational design that examined the association between any screen-time behaviour and dietary intake in preschool and school-aged children (younger than 12 years) were selected by two independent reviewers. If a consensus could not be reached, a third reviewer was consulted.Data extraction and synthesis Data were extracted independently by two reviewers using a pre-tested data extraction form. Risk of bias was assessed using an adapted version of the Newcastle-Ottawa Quality Assessment Scale for cross-sectional studies. A PRISMA flow chart was used to present the study selection results. The GRADE system was used to evaluate the strength of evidence. A qualitative synthesis was used to report the results. A meta-analysis was not conducted.Results Nineteen studies were included in the review, all of which were of cross sectional design or conducted cross-sectional analysis. Fourteen studies were assessed as high quality, three as moderate quality and two as low quality. All studies found a significant positive association between television and/or total screen-time viewing and poor quality diet including lower intake of fruit and vegetables and higher intake of unhealthy foods. Screen-based sedentary behaviour was positively associated with cariogenic foods consumption in 15 studies. Based on the GRADE rating, there was moderate evidence of an association between TV viewing and intake of potentially cariogenic diet.Conclusions Although there could be an association between TV viewing and poor quality cariogenic diet in preschool and school-aged children, the authors conclude that the strength of evidence is limited.Commentary.

Community engagement is an important element of the undergraduate programme at the Faculty of Medicine and Dentistry, University of Plymouth, United Kingdom. This report presents a project that a group of second year dental students undertook with people experiencing homelessness, and provides an in-depth reflective account of its impact on the students' learning. The project formed part of the students' inter-professional engagement module and delivered an intervention to enable residents at a temporary accommodation centre to access dental treatment. As a result of the project, 14 residents received dental treatment. The groups' confidence in engaging with people experiencing homelessness and their understanding of the complex needs of this group also significantly improved. Community engagement modules can be an important learning tool for students' future practice and can help promote access to dental care for vulnerable populations.

People with experience of homelessness commonly suffer from poor oral health and are likely to have low-level engagement with dental services. 'Teeth Matter' was a pilot study developed to examine whether peer education could result in improved plaque management among people who are experiencing homelessness. Based on the experience gained from developing and implementing the study, and taking into consideration the views of everyone involved, this paper provides a list of suggestions and resources that can be used to improve engagement of this population with oral health promotion activities. Some of the learning points are also applicable in the clinical setting.

Introduction People who experience homelessness have poor oral health and limited access to dental services.Aim To examine whether 'peer education' could yield improved plaque management among people experiencing homelessness.Methods A quasi-experimental, one-group pre-test-post-test study was conducted, with follow-up at one and two months. Participants were living in temporary accommodation in Plymouth, UK. Plaque levels were assessed using the simplified oral hygiene index. A questionnaire and the oral health impact profile (OHIP-14) were administered. Patient satisfaction and barriers to dental care were explored by interviews.Results The baseline sample included 24 people with a mean age of 36.88 ± 10.26 years. The mean OHIP-14 score was 25.08 ± 19.56; finding it uncomfortable to eat and being embarrassed attracted the highest values (2.46 ± 1.53 and 2.33 ± 1.63, respectively). Plaque levels decreased by month one and month two, though the changes were not statistically significant. Positive changes in confidence in toothbrushing at month two were identified (p = 0.01).Conclusion Experiencing pain and the opportunity to access treatment were key drivers of study participation. The study indicated that it is feasible to conduct oral health promotion projects for people in temporary accommodation. Adequately powered studies examining the impact of peer education on improving homeless people's oral health are warranted.

Background: Obesity and caries in young people are issues of public health concern. Even though research into the relationship between the two conditions has been conducted for many years, to date the results remain equivocal. The aim of this paper was to determine the nature of the relationship between Body Mass Index (BMI) and caries in children and adolescents, by conducting a systematic review of the published literature., Methods: A systematic search of studies examining the association between BMI and caries in individuals younger than 18 years old was conducted. The electronic bibliographic databases PubMed, MEDLINE, Embase, CINAHL, CENTRAL and Google Scholar were searched. References of included studies were checked to identify further potential studies. Internal and external validity as well as reporting quality were assessed using the validated Methodological Evaluation of Observational Research checklist. Results were stratified based on the risk of flaws in 14 domains 10 of which were considered major and four minor., Results: Of the 4208 initially identified studies, 84 papers met the inclusion criteria and were included in the review; conclusions were mainly drawn from 7 studies at lower risk of flaws. Three main types of association between BMI and caries were found: 26 studies showed a positive relationship, 19 showed a negative association, and 43 found no association between the variables of interest. Some studies showed more than one pattern of association. Assessment of confounders was the domain most commonly found to be flawed, followed by sampling and research specific bias. Among the seven studies which were found to be at lower risk of being flawed, five found no association between BMI and caries and two showed a positive association between these two variables., Conclusions: Evidence of an association between BMI and caries was inconsistent. Based on the studies with a low risk lower risk of being flawed, a positive association between the variables of interest was found mainly in older children. In younger children, the evidence was equivocal. Longitudinal studies examining the association between different indicators of obesity and caries over the life course will help shed light in their complex relationship.

Objectives: The aim of this systematic review was to identify and conceptualize the barriers and enablers to accessing dental services for people experiencing homelessness in the United Kingdom., Methods: A literature search for studies relevant to homelessness and dental care was conducted. The PRISMA and ENTREQ guidelines were followed. Electronic databases (EMBASE, MEDLINE, DOSS, CINAHL, SOCINDEX and PsycINFO) and grey literature sources (Electronic Theses Online Service - EThOS, Kings Fund, NICE Evidence, Open Grey, Google and the Health Foundation) were searched up to 28 August 2018. The critical appraisal was conducted using CASP and an adjusted version of a JBI Critical Appraisal tool. Thematic analysis was used to develop the themes and domains., Results: Twenty-eight papers were included. Barriers to homeless people accessing dental care stemmed both from the lived experience of homelessness and the healthcare system. Within homelessness, the themes identified included complexity, emotions and knowledge. Regarding the healthcare system, identified themes included staff encounter, accessibility and organization issues., Conclusion: Homelessness can actively contribute to both an increased need for dental care and barriers to accessing that care. The arrangement of dental healthcare services can also act as barriers to care. This is the first systematic review to conceptualize the factors associated with access to dental care for people who are homeless. It provides a set of recommendations for overcoming the main barriers for homeless people to accessing dental care. It also offers directions for future research, policy and commissioning., (© 2019 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Background: Obesity and caries are common conditions in childhood and can have significant implications on children's wellbeing. Evidence into their association remains conflicting. Furthermore, studies examining the ssociation between obesity and caries commonly focus on individual-level determinants. The present study aimed to examine the association between obesity and caries in young English children and to determine the impact of deprivation and area-level characteristics on the distribution of the two conditions., Methods: This was a cross-sectional study among children in Plymouth city aged four-to-six years. Anthropometric measurements included weight and height (converted to Body Mass Index centiles and z-scores), and waist circumference. Caries was assessed by using the sum of the number of teeth that were decayed, missing or filled. A questionnaire was used to obtain information on children's demographic characteristics, oral hygiene, and dietary habits. The impact of deprivation on anthropometric variables and caries was determined using Linear and Poisson regression models, respectively. Multiple logistic regression was used to assess the association between different anthropometric measures and caries. Logistic regression models were also used to examine the impact of several demographic characteristics and health behaviours on the presence of obesity and caries., Results: The total sample included 347 children aged 5.10 ± 0.31 (mean ± SD). Deprivation had a significant impact on caries and BMI z-scores (p < 0.05). Neither BMI- nor waist circumference z-scores were shown to be significantly associated with dental caries. Among the neighbourhood characteristics examined, the percentage of people dependent on benefits was found to have a significant impact on caries rates (p < 0.05). Household's total annual income was inversely related to caries risk and parental educational level affected children's tooth brushing frequency., Conclusions: No associations between any measure of obesity and caries were found. However, deprivation affected both obesity and caries, thus highlighting the need to prioritise disadvantaged children in future prevention programmes.

Purpose: The purpose of this study is to assess tobacco dependence among Cypriot adolescents and examine its association to cigarette consumption and attitudes towards smoking., Methods: The current study used cross-sectional data from the 2011 Cyprus Global Youth Tobacco Survey which adopted multistage cluster sampling methods to select adolescents registered in middle and high schools in Cyprus. Tobacco use, physical dependence on tobacco, and attitudes towards tobacco use were measured in 187 adolescents aged 13-18years old who reported that they had smoked at least once in the preceding 30days. Physical dependence was assessed using the Levels of Physical Dependence scale., Results: Physical dependence was present in 86% of the adolescent smokers. The mean latency to needing among smokers in the highest dependence group was 101h. Significant associations were observed between physical dependence and the perceived difficulty in quitting (OR=13.1, 95% CI: 4.0, 43.0) as well as the expectation to continue smoking for the next five years (OR=3.3, 95% CI: 1.3, 8.4). Significant associations were also observed between physical dependence and the number of smoking days per month, daily smoking, daily cigarette consumption, lifetime cigarette consumption, and perceived difficulty in abstaining from smoking for one week., Conclusions: Physical dependence provides a symptom-based approach to assess dependence and it is a strong predictor of adolescents' perceptions of their ability to quit or to refrain from smoking for a week. Physical dependence on tobacco was highly prevalent among adolescent smokers in Cyprus and it was associated with greater perceived difficulty in quitting. Interventions targeting adolescent smoking must account for the high prevalence of physical dependence., (Copyright © 2016 The Authors. Published by Elsevier Ltd.. All rights reserved.)

Objectives: To identify factors associated with adolescent smokers' desire to quit based on the 2006 Cyprus Global Youth Tobacco Survey., Methods: A cluster sample design was used to select a representative sample of students from all registered middle and high schools in Cyprus with >40 students in academic year 2005-2006. Multivariable logistic regression was used taking into account the weight associated with each of the respondents., Results: Out of the total sample with available information (N=12,629), 1591 students were current smokers (weighted frequency=14%) and were included in the analysis, with 734 (46.1%) of them reporting that they want to quit smoking. In both males and females, strong predictors of intention to quit smoking include past quit attempts and physical activity. Intention to quit is also associated with the belief that smoking is harmful to them and inversely associated with having peers who smoke, in boys, and the belief that smoking is harmful to others and perceiving smokers as less attractive, and inversely associated with pocket money, in girls., Conclusions: The present study has identified factors that appear to influence youth's intention to quit tobacco, which is of major importance in developing successful tobacco cessation programs targeting adolescents., (Copyright © 2013 Elsevier Inc.

Background: Several countries, including Cyprus, have passed smoke-free legislations in recent years. The goal of this study was to assess the indoor levels of particulate matter in hospitality venues in Cyprus before and after the implementation of the law on 1/1/2010, evaluate the role of enforcement, and examine the legislation's effect on revenue and employment., Methods: Several hospitality venues (n = 35) were sampled between April 2007 and January 2008, and 21 of those were re-sampled after the introduction of the smoking ban, between March and May 2010. Data on enforcement was provided by the Cyprus Police whereas data on revenue and employment within the hospitality industry of Cyprus were obtained from the Cyprus Statistical Service; comparisons were made between the corresponding figures before and after the implementation of the law., Results: The median level of PM2.5 associated with secondhand smoking was 161 μg/m3 pre-ban and dropped to 3 μg/m3 post-ban (98% decrease, p < 0.0001). Furthermore, in the year following the ban, the hotel turnover rate increased by 4.1% and the restaurant revenue by 6.4%; employment increased that same year by 7.2% and 1.0%, respectively., Conclusion: Smoke free legislations, when enforced, are highly effective in improving the air quality and reducing the levels of indoor PM2.5. Strict enforcement plays a key role in the successful implementation of smoking bans. Even in nations with high smoking prevalence comprehensive smoking laws can be effectively implemented and have no negative effect on accommodation, food, and beverage services.

Background: A preliminary study was undertaken in a community of Cyprus where low-level arsenic (As) concentrations were recently detected in the groundwater that was chronically used to satisfy potable needs of the community. The main objective of the study was to assess the degree of association between orally-ingested As and self-reported type-2 diabetes mellitus (DM) in 317 adult (≥18 years old) volunteers., Methods: Cumulative lifetime As exposure (CLAEX) (mg As) was calculated using the median As concentrations in water, individual reported daily water consumption rates, and lifetime exposure duration. Logistic regression models were used to model the probability of self-reported DM and calculate odds ratios (OR) in univariate and multivariate models., Results: Significantly higher (p < 0.02) CLAEX values were reported for the diabetics (median = 999 mg As) versus non-diabetics (median = 573 mg As), suggesting that As exposure could perhaps be related to the prevalence of DM in the study area, which was 6.6%. The OR for DM, comparing participants in the 80th versus the 20th percentiles of low-level As CLAEX index values, was 5.0 (1.03, 24.17), but after adjusting for age, sex, smoking, education, and fish consumption, the As exposure effect on DM was not significant., Conclusions: Further research is needed to improve As exposure assessment for the entire Cypriot population while assessing the exact relationship between low-level As exposure and DM.

Background: There are concerns about the future health of young people due to inactive lifestyles. However, evidence about their physical activity levels is not extensive, especially with regard to affluent young people. This study aimed to investigate whether young people from affluent backgrounds met public health recommendations for physical activity., Methods: Diary accounts of lifestyle activity were collected from 219 students ages 9 to 15 years attending a fee-paying school in England., Results: Pupils spent an average of 121 minutes per day participating in physical activities of at least moderate intensity, considerably more than public health recommendations of 60 minutes per day. However, almost a quarter of these young people engaged in less than 60 minutes of physical activity per day of at least moderate intensity., Conclusions: The picture to emerge was one of a balance between sedentary pursuits such as television and homework and physical activities such as sport and active play.
