The total years lived with disability among older people, and the concomitant burden of tooth loss in ageing societies have increased. This study is an overview of the burden of oral diseases and access to oral care in an ageing society.We selected key issues related to the burden of oral diseases and access to oral care and reviewed the relevant literature.The rising number of older people with teeth increases their oral health care needs. To improve access to oral care, affordability of care is a great concern with respect to universal health coverage. In addition, accessibility is a crucial issue, particularly for vulnerable older adults. To improve oral care access, attempts to integrate oral health care into general care are being made in ageing countries. For this purpose, provision of professional oral care at home through domiciliary visits and provision of daily oral health care by non-dental professional caregivers are important. Oral health care for older people reduces general diseases such as pneumonia and malnutrition, which in turn could reduce further healthcare costs.To address the growing burden of oral care in ageing societies, special provision of oral health care to vulnerable older people, and integration of oral care with primary care will be required.

International audience; Il existe un besoin pour une approche théoriquement informée et contextualisée pour mesurer la santé bucco-dentaire dans une perspective multidisciplinaire qui va au-delà des indices cliniques et des mesures sociodentaires couramment utilisés. Ce commentaire vise à discuter du potentiel de la Classification internationale du fonctionnement, du handicap et de la santé (CIF) de l'OMS à fournir un modèle pour le développement d'indicateurs de la santé bucco-dentaire. Il est suggéré que la CIF pourrait fournir à la fois un modèle théorique et une classification opérationnelle pour les indicateurs de la santé bucco-dentaire. Le modèle de la CIF stipule que l'expérience humaine du fonctionnement physique, cognitif et social est universelle et peut donc être décrite et qualifiée. La fonction humaine se voit attribuer un contexte social et environnemental dans le modèle, tant au niveau individuel qu'au niveau de la population. L'ICF peut non seulement capturer des données concernant la santé bucco-dentaire et la fonction au niveau physiologique (par exemple la mastication) mais aussi au niveau social (par exemple le partage des repas). Il est capable de saisir non seulement des aspects de comportement préventif (par exemple, soins dentaires), mais également des aspects de facilitation sociale (par exemple, autonomie économique) ou de capacité à remplir un rôle social (par exemple, emploi rémunéré). Il comprend également des aspects de l'environnement social, tels que les services de santé ou les systèmes politiques, économiques et juridiques. Des études de cas sont présentées comme exemples de l'utilisation potentielle de la CIF dans le domaine de la santé bucco-dentaire. Des exemples sont également donnés des premières étapes qui ont été franchies vers l'opérationnalisation de la CIF dans la collecte de données et la recherche en santé bucco-dentaire. Les défis d'englober un tel modèle complet dans une mesure pratique de santé bucco-dentaire sont discutés.

While the impact of the coronavirus disease (COVID-19) pandemic on health inequalities is documented, oral health has been absent from this discussion. This commentary highlights the potential impacts of the COVID-19 pandemic on oral health inequalities in England in February 2021. It includes a literature review, Public Health England and Kantar Worldpanel sales data on health behaviours and analysis of NHS dental services data. Purchasing data indicate, except for smoking, increases in health-compromising behaviours. Since the resumption of dental services, NHS general dental service use modestly recovered among adults but not children by October 2020. There are clear inequalities among children and older adults, with more deprived groups having lower uptake of dental service use than more affluent groups. Oral cancer referrals and hospital admissions for tooth extractions in children dramatically declined, with the latter primarily affecting children in more deprived areas. Many oral health programmes in schools and care homes were disrupted or suspended throughout this period. All these indicate that oral health inequalities have widened due to the COVID-19 pandemic. An oral health plan of action requires prioritising long-term investment in public health programmes and transforming commissioning pathways to support those with the greatest needs to access oral healthcare services.

Objectives To examine whether oral health-related quality of life (OHRQoL) explained the negative associations between dental caries and anthropometric measures of child growth among a sample of 5- to 9-year-old children in Dhaka, Bangladesh, while taking potential confounding factors (maternal education, family income, study setting, child's birth weight and childhood diseases) into account. In addition, to test whether specific oral impacts had a role in explaining these associations. Methods Data collection was conducted via a cross-sectional survey among children and their parents from both hospital and school settings in Dhaka. Dental caries and severe consequences of dental caries (defined here as dental sepsis) were the exposure variables, and age- and sex-adjusted height-z-scores (HAZ), weight-z-scores (WAZ) and BMI-z-scores (BAZ) were the outcome variables. OHRQoL was measured using the Bengali version of the Scale of Oral Health Outcomes for 5-year-old children (SOHO-5). First, associations between oral impacts (prevalence of overall impacts and specific items of the SOHO-5) and outcome measures were assessed. Multiple linear regression was used to assess associations between caries and anthropometric measures, adjusted for potential confounders. Oral impacts were then added to test whether their inclusion attenuated the associations between exposures and outcomes. To further investigate potential mediating role of oral impacts, structural equation modelling (SEM) was used to test the hypothesis that dental caries and sepsis were associated with the outcomes directly and also indirectly via oral impacts in general. A similar approach was used to investigate mediation by specific SOHO-5 items. Results The sample consisted of 715 children, 73.1% of whom had dental caries, 37.5% presented with sepsis, and 57.3% reported at least one oral impact (SOHO-5 score ≥1). Prevalence of overall oral impacts and also the impact on 'eating difficulty' (a specific item of SOHO-5) were negatively associated with all three outcomes. Dental caries and sepsis was associated with lower HAZ, WAZ and BAZ, and adjustment for overall oral impacts considerably attenuated the associations between 'severe dental caries' and outcomes, and dental sepsis and outcomes. Using SEM, we found significant indirect associations between caries and sepsis and anthropometric measures via oral impacts (except for dental caries and HAZ). Considering specific oral impacts, eating difficulties explained about 44% and 65% of the associations between caries and anthropometric outcomes, and dental sepsis and anthropometric outcomes, respectively. Conclusions Oral impacts, in particular eating difficulties, appear to mediate associations between caries and markers of child growth among this population.

To assess the longitudinal trends in social inequalities in early childhood caries (ECC) using collected population-based data.Clinical data on children were routinely collected from 2008 to 2019 in Victoria, Australia. ECC prevalence and severity (dmft) were quantified according to Indigenous status, culturally and linguistically diverse (CALD) status, concession cardholder status, geographic remoteness and area deprivation. The inverse probability weighting was used to quantify social inequalities in ECC. The weighted prevalence differences, and the ratio between the weighted prevalence of ECC and mean dmft and their 95% confidence interval, were then plotted.Absolute inequalities in ECC prevalence increased for children by 7% for CALD status and cardholder status between 2008 and 2019. Likewise, absolute inequalities in ECC severity in this time period increased by 0.6 for CALD status and by 0.4 for cardholder status. Relative inequalities in ECC increased by CALD (ratio: 1.3 to 2.0), cardholder status (1.3 to 2.0) and area deprivation (1.1 to 1.3). Relative inequalities in severity increased by CALD (1.5 to 2.8), cardholder (1.4 to 2.5) or area deprivation (1.3 to 1.5). Although children with Indigenous status experienced inequalities in ECC prevalence and severity, these did not increase on the absolute (ECC: 0.1-0.1 Severity: 1.0-0.1) or relative scale (ECC ratio: 1.3-1.3 Severity ratio: 1.6-1.1).Trends in inequalities in ECC were different according to sociodemographic measures. Oral health policies and interventions must be evaluated on the basis of reducing the prevalence of oral diseases and oral health inequalities between population sub-groups.

To assess the association between aspects of the dentist-patient relationship at age 65 and Oral Impacts on Daily Performances (OIDP) at ages 65 and 70 and to examine whether dental avoidance behaviours play a role in explaining that association.Information about the quality of the dentist-patient relationship is important for dental care provision and healthy ageing.Secondary data analysis of a cohort study of Norwegians born in 1942. The participation rate in 2007 (age 65) and 2012 (age 70) was, respectively, 58.0% (n = 4211) and 54.5% (n = 3733). A total of 70.0% (n = 2947) of the baseline participants responded in 2012. Dentist-patient relationship aspects were assessed in terms of communication with the dentist, satisfaction with dental care, unpleasant experiences and changes of dentist. Generalised Estimating Equations (GEEs) were used to account for repeated measurements.Prevalence of oral impacts (OIDP) was 29.0% in 2007 and 28.4% in 2012. Participants who received communication on oral hygiene during dental visits had a higher likelihood, whereas participants who reported satisfaction with dental care, no unpleasant experience and did not change dentist had a lower likelihood of reporting oral impacts over these 5 years. Corresponding odds ratios were: 1.2 (95% CI 1.0-1.5), 0.4 (95% CI 0.3-0.5), 0.6 (95% CI 0.5-0.7) and 0.5 (95% CI 0.3-0.6). Associations between dentist-patient relationship aspects and OIDP remained unchanged after adjustment for avoidance behaviours.Training dentists in relationship skills might improve social interaction with patients and the oral health-related quality of life of older people in Norway.

Background Oral health is a critical issue for public health and poor oral health is associated with significant chronic health conditions and lower quality of life. There has been little focus on providing oral health care to people who receive care in their own homes, despite the high risk of poor oral health in older people. Nurses practicing in the community are well placed to deliver this care, but little is known about how to build this capability through education or training interventions. Methods A scoping review methodology was employed to find and review studies of oral health interventions involving populations of people receiving care in their own home or those nurses who deliver this care. The research question asked what previous research tells us about oral health interventions delivered by nurses in the community. Data was extracted for four areas: setting and type of intervention, patient outcomes, changes to nursing practice and implementation and process evaluations of interventions. Results Two thousand eighty papers were found from the searches, and only nine were ultimately deemed eligible for inclusion in the review. Included studies spanned community nursing for older people (n = 3) and health visiting or community nursing for children and infants (n = 6). Patient outcomes were generally positive, but this is based on a low level of evidence. Changes to practice including increased oral health care administered by nurses were found, but this required professional support to be sustainable. Conclusions This review has found that there is a clear gap in the research around interventions designed to be used by community nurses to improve oral health care for people receiving care in their own homes. The results also suggest that any future intervention must make use of a participatory, co-design approach and consider the complex setting of nursing practice in the community and the barriers to delivering this care, such as time pressure and lack of prior experience.

Objectives: The aim of this study was to assess the association between different levels of frailty and dental attendance among home-dwelling older adults, in Belgium. Background: While many determinants of dental attendance among older adults have been identified, no study has focused on the role of frailty. Materials and methods: This was a cross-sectional study on a random sample of home-dwelling adults aged 60 and over from two Belgian cities. Data were collected with a structured questionnaire through a participatory peer-research method. Time since the last dental attendance was the dependent variable. The independent variable was frailty, assessed with the Comprehensive Frailty Assessment Instrument, including physical, psychological, social, and environmental subdomains. Covariates were age, gender, having a partner, educational level, and household income, as well as self-perceived oral health. Data analysis included descriptive, bivariate (Chi-Square, ANOVA, and Kruskal-Wallis), and binomial logistic regression analyses. Results: The sample consisted of 1329 older adults with a mean age of 72.5 years (SD 8.9, range 60-103). In the low frailty group, 73% attended the dentist in the previous 12 months, while it was 62% and 54% in the medium and high frailty groups, respectively. In the fully adjusted model, the initial gradient in the relationship between overall frailty and dental attendance remained; those in the medium and the high frailty groups were respectively 1.46 (95% CI: 1.09, 1.95) and 1.67 (95% CI: 1.15, 2.43) times more likely to report no dental attendance in the previous year than the low frailty group. Similar associations could be seen in the physical and environmental frailty subdomains. Conclusion: Frailty is consistently associated with less favourable dental attendance, independent from age, gender, socioeconomic factors, family composition, and self-perceived oral health. Once frailty has been detected, good interprofessional communication and care are needed to avoid the drop-out of older adults from the oral healthcare system.

Objectives To identify the existing OHRQoL instruments for adults, describe their scope (generic or specific), theoretical background, validation type and cross-cultural adaptation. Methods A systematic search was conducted, and articles presenting validation of OHRQoL instruments in adults were included. Data were collected about the validation type: external validation (correlations/associations); or internal validation (factor analysis/principal components analysis, item response theory); and cross-cultural adaptation. Results Of 3730 references identified, 326 were included reporting 392 studies. Forty-two original instruments were found among 74 different versions, 40 generic and 34 condition-specific. Locker's theoretical framework was the predominant model. The oral health impact profile (OHIP) presented 20 versions, with OHIP-14 being the most frequent (26.8%), followed by geriatric oral assessment index (GOHAI) (14.0%), OHIP-49 (11.7%) and oral impacts on daily performances (OIDP) (9.7%). Most studies focused on external validation (65.3%), while internal validation was reported in 24.8% (n = 26) of OHIP-14 studies, 50.9% (n = 28) of GOHAI and 21.1% (n = 8) of OIDP studies. Most internal validation studies were conducted in English-speaking countries (n = 33), and cross-cultural adaptation was mostly in non-English-speaking European countries (n = 40). Conclusions Many generic and condition-specific instruments were found, but few have gone through a rigorous internal validation process or have undergone cross-cultural adaptation. This, in turn, makes it difficult for researchers to choose an appropriate measure based on known psychometric properties. OHIP-14, OIDP and GOHAI seem to be the most widely validated instruments. Equalizing measurement properties for comparability are challenging due to theoretical heterogeneity. Future studies should assess psychometric properties, explore the factorial structure and work towards a consensus on critical issues.

Objectives This study aimed to investigate the influence of community water fluoridation on ethnic inequalities in untreated dental caries among children and adolescents in Brazil while taking the human development context into account. Methods Data from a nationwide Brazilian epidemiological population oral health survey were used (SB Brazil 2010). Outcomes were caries prevalence measured by the proportion of individuals with one or more untreated decayed teeth and caries severity defined by the mean number of untreated decayed teeth (DT). Three different contexts were considered: 1-cities with no water fluoridation; 2-cities with water fluoridation and low Human Development Index (HDI); and 3-cities with water fluoridation and high HDI. The exposure was ethnic/racial group (White, Pardo, Black) and covariates were age, sex and household income. Multilevel logistic and negative binomial regressions were performed with 6696 children (aged 5 years) and 11 585 adolescents (aged 12 and 15-19 years). Results For both children and adolescents, ethnic differences in caries prevalence and mean DT were found in the nonfluoridated cities with low HDI and also in cities with high HDI, most of which were fluoridated. For example in nonfluoridated cities with low HDI, 5-year-old Pardo children were more likely to have untreated decay (OR = 1.22; 95% CI: 1.02, 1.46) and had more decayed teeth (RR = 1.18; 95% CI: 1.04, 1.34) than their White counterparts after adjusting for sex and household income. No statistically significant differences were observed in fluoridated cities with low HDI. Conclusion Water fluoridation appears to be associated with reduced ethnic inequalities in dental caries prevalence and mean DT among children and adolescents in more disadvantaged settings.

The primary aim of this study was to assess any long-term association between tooth loss at age 50 and subsequent impaired oral health-related quality of life, OHRQoL, at age 65, 70 and 75, adjusted for time invariant socio-demographic-and time variant behavioural and age-related factors in terms of disadvantages with functional, social, health and psychological concerns. As a second aim, this study examined whether behavioural- and age-related factors played a role in explaining any long-term association between early tooth loss and subsequent OHRQoL.In 1992, 6346 residents, aged 50, consented to participate in a prospective cohort study and 3060 completed postal questionnaire follow-ups every fifth year (six in total) until 2017. Information on tooth loss was assessed at baseline at age 50. Behavioural- and age-related covariates were assessed repeatedly at ages 65, 70 and 75. OHRQoL was the repeated outcome measure assessed by the Oral Impact on Daily Performance, OIDP at age 65, 70 and 75. Generalized Estimating Equations, GEE, with binomial logit function was used to test the association between tooth loss and prevalence of oral impacts (OIDP) adjusting for counfounders and potential mediators. The role of behavioural and age-related factors in explaining the association between early tooth loss and OHRQoL was tested using the change in estimate approach.Tooth loss and time variant behavioural- and age-related covariates associated independently with higher odds of impaired OHRQoL across time. The long-term impact of tooth loss seemed to be partly explained by time variant covariates related to functional and psychological concerns. Participants who had excessive tooth loss at age 50 were 2.5 times more likely to experience oral impacts before adjustment of covariates. After adjustment of functional- and psychological-covariates, participants were, respectively, 1.6 times and 1.4 times more likely to experience oral impacts.This study revealed that early tooth loss at age 50 was independently associated with subsequent impaired OHRQoL at ages 65, 70 and 75. The aspects of behavioural- and age-related factors in terms of disadvantages in functional and psychological concerns seemed to play a role in explaining the long-term impact of tooth loss on impaired OHRQoL. A mid-life approach to the prevention of tooth loss for the protection of subsequent adverse health outcomes should guide health promotion interventions and also be recognized by oral health care providers both for patient interaction and clinical decision making.

Contains fulltext : 238877.pdf (Publisher’s version ) (Closed access) BACKGROUND/OBJECTIVES: Tooth loss is associated with reduced functional capacity, but so far, there is no relevant causal evidence reported. We investigated the causal effect of tooth loss on the instrumental activities of daily living (IADL) among older adults in England. DESIGN: Natural experiment study with instrumental variable analysis. SETTING: The English Longitudinal Study of Aging (ELSA) combined with the participants' childhood exposure to water fluoride due to the community water fluoridation. PARTICIPANTS: Five thousand six hundred and thirty one adults in England born in 1945-1965 participated in the ELSA wave seven survey (conducted in 2014-2015; average age: 61.0 years, 44.6% men). MEASUREMENTS: The number of natural teeth predicted by the exogenous geographical and historical variation in exposure to water fluoride from age 5 to 20 years old (instrumental variable) was used as an exposure variable. The outcome, having any limitations in IADL (preparing a hot meal, shopping for groceries, making telephone calls, taking medications, doing work around the house or garden, or managing money), was assessed by self-reported questionnaires. RESULTS: Linear probability model with Two-Stage Least Squares estimation was fitted. Being exposed to fluoridated water was associated with having more natural teeth in later life (coefficient: 0.726; 95% confidence interval (CI) = 0.311, 1.142; F = 11.749). Retaining one more natural tooth reduced the probability of having a limitation in IADL by 3.1 percentage points (coefficient: -0.031; 95% CI = -0.060, -0.002). CONCLUSION: Preventing tooth loss maintains functional capacity among older adults in England. Given the high prevalence of tooth loss, this effect is considerable. Further research on the mechanism of the observed causal relationship is needed.

Contains fulltext : 232750.pdf (Publisher’s version ) (Open Access) OBJECTIVE: To develop a minimum Adult Oral Health Standard Set (AOHSS) for use in clinical practice, research, advocacy and population health. MATERIALS AND METHODS: An international oral health working group (OHWG) was established, of patient advocates, researchers, clinicians and public health experts to develop an AOHSS. PubMed was searched for oral health clinical and patient-reported measures and case-mix variables related to caries and periodontal disease. The selected patient-reported outcome measures focused on general oral health, and oral health-related quality of life tools. A consensus was reached via Delphi with parallel consultation of subject matter content experts. Finally, comments and input were elicited from oral health stakeholders globally, including patients/consumers. RESULTS: The literature search yielded 1,453 results. After inclusion/exclusion criteria, 959 abstracts generated potential outcomes and case-mix variables. Delphi rounds resulted in a consensus-based selection of 80 individual items capturing 31 outcome and case-mix concepts. Global reviews generated 347 responses from 87 countries, and the patient/consumer validation survey elicited 129 responses. This AOHSS includes 25 items directed towards patients (including demographics, the impact of their oral health on oral function, a record of pain and oral hygiene practices, and financial implications of care) and items for clinicians to complete, including medical history, a record of caries and periodontal disease activity, and types of dental treatment delivered. CONCLUSION: In conclusion, utilising a robust methodology, a standardised core set of oral health outcome measures for adults, with a particular emphasis on caries and periodontal disease, was developed.

Patient-based outcomes complement clinical data with patients' self-evaluation of their physical, psychological, and social well-being, and as such facilitate clinical decision-making, assessing the quality of care provided, and evaluating practices and policies. Some validated generic oral health-related quality of life measures used in recent research indicated a high performance. There is a proportional relationship between the quality of life and periodontitis, ie, the higher the level of periodontitis, the poorer the oral health-related quality of life. This relationship is heightened by the presence of symptoms such as bleeding, halitosis, and mobility. On the other hand, periodontal treatment has demonstrated the capability to improve quality of life substantially. Future research should focus on questionnaires that are able to explain the interlinked pathways between periodontal conditions, approaches to treatment approaches, and patients' well-being. The acquisition of new knowledge in the field is essential for the whole community, as we treat people not millimeters.

Specific measures to evaluate positive oral health have been in a nascent stage in Dentistry, especially in developing countries. The present study aimed to translate, cross-culturally adapt and evaluate the psychometric properties of the Brazilian version of Positive Oral Health and Well-Being (B-POHW). After forward-backwards translation to Brazilian Portuguese language, the cross-cultural adaptation of B-POHW was pretested, followed by the main study to perform psychometric analysis. We tested the model fit by Confirmatory Factor Analysis with categorical factor indicators in bifactor and simple structure models on a sample of 209 participants (mean age: 39.36 ± 12.26. Questionnaires about sociodemographic status, self-reported oral health-related outcomes, and general well-being were administered and used as external validation measures. Moreover, dental caries experience was clinically diagnosed. For test-retest reliability, 53 participants completed the B-POHW a fortnight later. The following results were found: a) the bifactor model presented the best model fit; b) the B-POHW demonstrated satisfactory internal consistency (Cronbach's α and McDonald's ω > 0.8); c) the intraclass correlation coefficient suggested good reliability for the Global Factor of B-POHW in the test-retest (ICC = 0.84); d) evidence based on other variables and construct representation was in line with the positive oral health framework. The B-POHW is psychometrically sound to be used in a Brazilian context, and evidence of its internal structure confirmed its theoretical framework for measuring positive oral health. These findings advance in holistic approaches, enabling to assess positive oral health in Dental practice in Brazil.

Objectives: Although inequalities in dental implant use based on educational level have been reported, no study has used income as a proxy for the socioeconomic status. We examined: (i) income inequalities in implant use; and (ii) whether income or education has a stronger association with implant use in elder Japanese. Methods: In 2016, a self-reported questionnaire was mailed to participants aged 65 years or older living across Japan as part of the ongoing Japan Gerontological Evaluation Study. We used data from 84,718 respondents having 19 or fewer teeth. After multiple imputation, multi-level logistic regression estimated the association of dental implant use with equivalised income level and years of formal education. Confounders were age, sex, and density of dental clinics in the residential area. Results: 3.1% of respondents had dental implants. Percentages of dental implant use among the lowest (≤ 9 years) and highest (≥ 13 years) educational groups were 1.8 and 5.1, respectively, and among the lowest (0 < 12.2 ‘1,000 USD/year’) and highest (≥ 59.4 ‘1,000 USD/year’) income groups were 1.7 and 10.4, respectively. A fully adjusted model revealed that both income and education were independently associated with dental implant use. Odds ratios for implant use in the highest education and income groups were 2.13 [95% CI = 1.94–2.35] and 4.85 [95% CI = 3.78–6.22] compared with the lowest education and income groups, respectively. From a model with standardised variables, income showed slightly stronger association than education. Conclusion: This study reveals a public health problem that even those with the highest education but low income might have limited accessibility to dental implant services.

BackgroundWhile inequalities in oral health are documented, little is known about the extent to which they are attributable to potentially modifiable factors. We examined the role of behavioural and dental attendance pathways in explaining oral health inequalities among adults in England, Wales and Northern Ireland.MethodsUsing nationally representative data, we analysed inequalities in self-rated oral health and number of natural teeth. Highest educational attainment, equivalised household income and occupational social class were used to derive a latent socioeconomic position (SEP) variable. Pathways were dental attendance and behaviours (smoking and oral hygiene). We used structural equation modelling to test the hypothesis that SEP influences oral health directly and also indirectly via dental attendance and behavioural pathways.ResultsLower SEP was directly associated with fewer natural teeth and worse self-rated oral health (standardised path coefficients, −0.21 (SE=0.01) and −0.10 (SE=0.01), respectively). We also found significant indirect effects via behavioural factors for both outcomes and via dental attendance primarily for self-rated oral health. While the standardised parameters of total effects were similar between the two outcomes, for number of teeth, the estimated effect of SEP was mostly direct while for self-rated oral health, it was almost equally split between direct and indirect effects.ConclusionReducing inequalities in dental attendance and health behaviours is necessary but not sufficient to tackle socioeconomic inequalities in oral health.

To examine the pathways between life course socioeconomic position (SEP) and general and oral health, assessing the role of two competing theories, social causation and health selection, on a representative sample of individuals aged 50 years and over in England.Secondary analysis from the English Longitudinal Study of Ageing Wave 3 data (n = 8659). Structural equation models estimated the social causation pathways from childhood SEP to adult self-rated general health and total tooth loss, and the health selection pathways from childhood health to adult SEP.There were direct and indirect (primarily via education, but also adult SEP, and behavior) pathways from childhood SEP to both health outcomes in older adulthood. There was a direct pathway from childhood health to adult SEP, but no indirect pathway via education. The social causation path total effect estimate was three times larger for self-rated general health and four times larger for total tooth loss than the health selection path respective estimates.The relationship between SEP and health is bidirectional, but with a clearly stronger role for the social causation pathway.

Prevalence of tooth loss has increased due to population aging. Tooth loss negatively affects the overall physical and social well-being of older adults. Understanding the role of socio-demographic and other predictors associated with tooth loss that are measured in non-clinical settings can be useful in community-level prevention. We used high-dimensional epidemiological data to investigate important factors in predicting tooth loss among older adults over a 6-year period of follow-up. Data was from participants of 2010 and 2016 waves of the Japan Gerontological Evaluation Study (JAGES). A total of 19,407 community-dwelling functionally independent older adults aged 65 and older were included in the analysis. Tooth loss was measured as moving from a higher number of teeth category at the baseline to a lower number of teeth category at the follow-up. Out of 119 potential predictors, age, sex, number of teeth, denture use, chewing difficulty, household income, employment, education, smoking, fruit and vegetable consumption, community participation, time since last health check-up, having a hobby, and feeling worthless were selected using Boruta algorithm. Within the 6-year follow-up, 3013 individuals (15.5%) reported incidence of tooth loss. People who experienced tooth loss were older (72.9 ± 5.2 vs 71.8 ± 4.7), and predominantly men (18.3% vs 13.1%). Extreme gradient boosting (XGBoost) machine learning prediction model had a mean accuracy of 90.5% (±0.9%). A visual analysis of machine learning predictions revealed that the prediction of tooth loss was mainly driven by demographic (older age), baseline oral health (having 10–19 teeth, wearing dentures), and socioeconomic (lower household income, manual occupations) variables. Predictors related to wide a range of determinants contribute towards tooth loss among older adults. In addition to oral health related and demographic factors, socioeconomic factors were important in predicting future tooth loss. Understanding the behaviour of these predictors can thus be useful in developing prevention strategies for tooth loss among older adults.

Introduction While different measures have been validated and used to assess the oral health related quality of life (OHRQoL) of children and adolescents, no previous study has tested the psychometric performance of OHRQoL amongst the most marginalized adolescents, living in extremely deprived neighbourhoods like urban slums and resettlement areas in modern cities. Our study assessed the internal consistency reliability, construct validity and Minimally Important Difference (MID) of the Child-OIDP in a sample of adolescents aged 12–15 years reporting oral health problems that lived in three different types (including two extremely vulnerable) of neighbourhoods (urban slums, resettlement colonies, and middle and upper middle-class neighbourhoods) in the National Capital Territory of Delhi. Methods We conducted data analysis on a cross-sectional study, comprising of 840 adolescents. The Child-OIDP was used as a measure of OHRQoL. Internal consistency reliability was tested using the standardized Cronbach’s Alpha Coefficient. The Child-OIDP was also tested for content and construct validity (the latter through the median test), while a distribution-based approach was used to identify the MID. Results The Indian Child-OIDP showed good internal consistency, as the Cronbach’s alpha coefficient was 0.77. Inter-item correlation coefficients among the items ranged from 0.13 to 0.50, with the mean inter-item correlation being 0.30. The corrected item-total correlations ranged from 0.30 (social contact) to 0.54 (speaking). For construct validity, the Child-OIDP extent was significantly associated with three subjective oral and general health variables in the expected direction. The calculated effect sizes for these differences indicated that they were moderate (0.50–0.79). We also calculated the standard error of measurement (SEM) of Child-OIDP extent as 0.75. Conclusion This study demonstrated that the Indian Child-OIDP is a reliable and valid measure for the assessment of the oral health related quality of life among Indian adolescents especially from marginalised and socioeconomically vulnerable groups. This is an essential step towards assessing oral health and evaluating oral health promotion interventions in those populations and settings.

Aims and objectives Oral health deteriorates following hospitalisation in critical care units (CCU) but there are no validated measures to assess effects on oral health-related quality of life (OHQoL). The objectives of this study were (i) to develop a tool (CCU-OHQoL) to assess OHQoL amongst patients admitted to CCU, (ii) to collect data to analyse the validity, reliability and acceptability of the CCU-OHQoL tool and (iii) to investigate patient-reported outcome measures of OHQoL in patients hospitalised in a CCU. Methods The project included three phases: (1) the development of an initial questionnaire informed by a literature review and expert panel, (2) testing of the tool in CCU (n = 18) followed by semi-structured interviews to assess acceptability, face and content validity and (3) final tool modification and testing of CCU-OHQoL questionnaire to assess validity and reliability. Results The CCU-OHQoL showed good face and content validity and was quick to administer. Cronbach’s alpha was 0.72 suggesting good internal consistency. For construct validity, the CCU-OHQoL was strongly and significantly correlated (correlation coefficients 0.71, 0.62 and 0.77, p Conclusions The new CCU-OHQoL tool may be of use in the assessment of oral health-related quality of life in CCU patients. Deterioration of OHQoL seems to be common in CCU patients.

BackgroundHealth inequalities, including inequalities in oral health, are problems of social injustice worldwide. Evidence on this issue from low-income and middle-income countries is still needed. We aimed to examine the relationship between oral health and different dimensions of socioeconomic position (SEP) in Colombia, a very unequal society emerging from a long-lasting internal armed conflict.MethodsUsing data from the last Colombian Oral Health Survey (2014), we analysed inequalities in severe untreated caries (≥3 teeth), edentulousness (total tooth loss) and number of missing teeth. Inequalities by education, income, area-level SEP and health insurance scheme were estimated by the relative index of inequality and slope index of inequality (RII and SII, respectively).ResultsA general pattern of social gradients was observed and significant inequalities for all outcomes and SEP indicators were identified with RII and SII. Relative inequalities were larger for decay by health insurance scheme, with worse decay levels among the uninsured (RII: 2.57; 95% CI 2.11 to 3.13), and in edentulousness (RII: 3.23; 95% CI 1.88 to 5.55) and number of missing teeth (RII: 2.08; 95% CI 1.86 to 2.33) by education, with worse levels of these outcomes among the lower educated groups. Absolute inequalities followed the same pattern. Inequalities were larger in urban areas.ConclusionHealth insurance and education appear to be the main contributors to oral health inequalities in Colombia, posing challenges for designing public health strategies and social policies. Tackling health inequalities is crucial for a fairer society in a Colombian post-conflict era and our findings highlight the importance of investing in education policies and universal health care coverage.

Contains fulltext : 215452.pdf (Publisher’s version ) (Closed access) Generating and implementing evidence-based policy is an important aim for many publicly funded health systems. In dentistry, this is based on the assumption that evidence-based health care increases the efficiency and effectiveness of interventions to improve oral health at a population level. This article argues that a linear logic model that links the generation of research evidence with its use is overly simplistic. It also challenges an uncritical interpretation of the evidence-based paradigm and explores approaches to the evaluation of complex interventions and how they can be embedded into policy and practice to improve oral health at a population level. 01 januari 2019

For the past four decades, a substantial body of work has been done to develop quality of life measurement in oral health. Much of the work has been developed using the 1980 WHO classification of Impairment, Disability and Handicap, later adapted for oral health measurement by Locker in 1988. Generic measures have been used in population surveys and clinical trials and have provided valuable insights into the impacts of oral diseases on the quality of life and subjective health of adults and children. This chapter provides an insight on the theoretical underpinnings and key applications of these subjective measures in research, discusses some of the measurement issues and highlights how measurement properties determine the usefulness of the currently available measures. Observations are offered on how the field of oral health-related quality of life measurement could be developed. Life span has increased in many countries, and the burden of chronic diseases is increasing. There is now more emphasis on improving the healthspan, and this is manifested by the use of terms such as ‘functional aging’. The WHO has developed the International Classification of Functioning, Disability and Health as a framework, which is a paradigm shift from the earlier focus on disease and disability. To date, there has been less emphasis on how this model will shape oral health-related quality of life assessment. This is an important area for further development, particularly the framing of oral health measurement in the wider context of the social determinants of health and value-based health care.

This chapter provides an overview for readers that incorporates considerations for the teaching of oral epidemiology at different educational levels. The chapter begins by placing the teaching of oral epidemiology within the wider pre-doctoral curriculum, and it acknowledges some of the challenges that may be encountered by students and teachers working at this level. In developing curricula, it is vital that teachers carefully consider the requirements of dental professional bodies, boards or councils to ensure that courses adhere to the educational expectations of the relevant local or national regulators. This chapter acknowledges these external factors and briefly explores the key course documents, learning objectives and other resources that may help guide students in their studies. Some of the teaching methods available are explored along with a number of their associated advantages and disadvantages. At various points within the chapter, there are a number of short ‘Tip’ boxes which describe or suggest ideas for teachers in delivering the curriculum. Selected methods for the assessment of students’ knowledge and skills are outlined, alongside considerations from the perspectives of students and teachers. Finally, the chapter ends with a brief description of different quality assurance methods which may be internal to the education provider or external through the involvement of visiting examiners and regulatory bodies.

Aim To investigate the relationship between generic and condition-specific (CS) quality of life, general psychological wellbeing and personality in patients with tooth wear. Materials and methods Ethical approval was granted (REC:10/H0709/21). Patients aged 18-70 years with tooth wear completed the Oral Impact on Daily Performance (OIDP) quality of life questionnaire, the NEO-FFI Personality questionnaire and the General Health Questionnaire-12 (GHQ). Tooth wear was measured with the Basic Erosive Wear Examination (BEWE). Results In total, 102 subjects were recruited. Increased BEWE scores were correlated with older age and worse generic and CS-related quality of life. Increased neuroticism was correlated with increased: generic and CS OIDP scores; generic and CS eating scores; CS smiling scores; and CS carrying out major work scores. Increased GHQ scores were positively correlated with increased: generic and CS OIDP scores; generic and CS eating scores; CS speaking scores; generic and CS cleaning scores; generic relaxing scores; generic and CS smiling scores; and generic emotional state scores (p

Background The numerous health risks of excessive alcohol consumption are well documented. Individuals at risk of harm from alcohol consumption can be identified through alcohol screening tools; however, there is limited research regarding their use in general dental practices.Methods Data were collected as part of a feasibility trial evaluating delivery of brief alcohol advice in general dental practices in North London. Patient demographics and health-related behaviours were collected, and the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) tool was used to assess alcohol consumption patterns.Results The analytical sample comprised 552 dental patients, of whom approximately half (46%) were drinking alcohol at hazardous levels. Males, younger adults, those who consumed red meat weekly and smokers all had significantly increased risks of excessive alcohol consumption. Smokers were more likely to consume excessive levels of alcohol irrespective of smoking frequency. Notable sex differences in alcohol consumption were identified, with males being more likely to consume alcohol frequently and in larger quantities than females.Conclusion The AUDIT-C tool can be used in general dental practice to screen for harmful levels of alcohol consumption. Clear associations exist between patient demographics, health behaviours and excessive alcohol consumption.

Background Individuals with Down syndrome exhibit particular oro-facial characteristics that may increase their risk of oral health problems. However, there is little research on the oral health of children and adults with Down syndrome and the way that oral health may affect Quality of Life (QoL). This study explored mothers’ perceptions of the oral health problems experienced by their children with Down syndrome and how these reported problems impacted the lives of the children and their families. Methods The study involved 20 in-depth, semi-structured interviews with mothers of children and adolescents aged 12–18 years with Down syndrome attending special care centres in Riyadh, Saudi Arabia. Results The predominant oral-health related problem reported by mothers was difficulty in speaking. Mothers also reported that tooth decay and toothache were problems that had undesirable effects on different aspects of their children’s QoL including: performing daily activities, emotional wellbeing, and social relationships. Poor oral health and functional problems had direct and indirect impacts on the family’s QoL as well. Conclusion Mothers perceived an array of QoL impacts from oral conditions, which affected their child with Down syndrome and the wider family.

Caries is the most prevalent chronic condition worldwide and the association between high-level intake of sugars and dental decay is strong and well established. Interestingly, to combat caries, dental practitioners and public health dentists in many countries have focused mainly on the application of different kinds of fluorides and fissure sealants but not on the reduction of sugar intake. Furthermore, for many years, sugars have not been the focus of dental research activities presented at the annual conferences of the European Organisation for Caries Research (ORCA) and the European Association of Dental Public Health (EADPH). In 2015, following the publication of the new WHO guidelines on the intake of sugars, the boards of ORCA and EADPH agreed to organize a common symposium entitled “Joint ORCA-ADPH Symposium on Sugar: The Oral Health Perspective”. This symposium was organized by a scientific committee and took place on July 6, 2016, in association with the 63rd ORCA Congress in Athens, Greece. It included 9 lectures highlighting different aspects of sugar consumption, contribution of sugar to dental caries, measuring sugar consumption, and fighting against sugar on a patient and public health basis. The purpose of this commentary is to give background information about the rationale of the above-mentioned symposium.

AIM This study aimed to assess associations between dental caries and anthropometric measures among a sample of children aged 5-9 years in Dhaka, Bangladesh. METHODS A cross-sectional observational study was conducted among 5- to 9-year-old children in Dhaka, Bangladesh. Data were collected from children and their parents attending the Dhaka Dental College Hospital and from three nearby primary schools. The outcome measures were as follows: age and sex adjusted height-z-scores (HAZ), weight-z-scores (WAZ) and BMI-z-scores (BAZ). Multiple linear regressions were used to assess the associations between caries and anthropometric measures, adjusted for maternal education, family income, study setting, birth weight and childhood diseases as potential confounders. RESULTS The final sample comprised 788 children, and the overall response rate was 96.7%. The majority (73.2%) had experience of dental caries. The mean dmft + DMFT score was 2.84 (95% CI 2.64, 3.03) and 35.8% experienced dental sepsis. Dental caries and sepsis were negatively associated with HAZ, WAZ and BAZ scores. After adjustment for potential confounders, children with severe levels of caries had lower HAZ scores (coefficient: -0.40; 95% CI -0.69, -0.10), lower WAZ scores (coefficient: -0.59; 95% CI -0.94, -0.24) and lower BAZ scores (coefficient: -0.50; 95% CI -0.87, -0.13) than those who were caries free. Children with moderate levels of caries also had lower WAZ scores (coefficient: -0.43; 95% CI -0.72, -0.15) and lower BAZ scores (coefficient: -0.43; 95% CI -0.72, -0.13) than caries-free children. Children with dental sepsis had lower HAZ (coefficient: -0.23; 95% CI -0.42, -0.03), WAZ (coefficient: -0.33; 95% CI -0.56, -0.10) and BAZ scores (coefficient: -0.29; 95% CI -0.53, -0.05) than dental sepsis-free children. CONCLUSIONS Dental caries was associated with lower height, weight and BMI among this sample of Bangladeshi children, even after adjusting for age and sex and a number of potential confounders.

Self-perceptions of own social position are potentially a key aspect of socioeconomic inequalities in health, but their association with mortality remains poorly understood. We examined whether subjective social status (SSS), a measure of the self-perceived element of social position, was associated with mortality and its role in the associations between objective socioeconomic position (SEP) measures and mortality. We used Cox regression to model the associations between SSS, objective SEP measures and mortality in a sample of 9972 people aged ≥ 50 years from the English Longitudinal Study of Ageing over a 10-year follow-up (2002–2013). Our findings indicate that SSS was associated with all-cause, cardiovascular, cancer and other mortality. A unit decrease in the 10-point continuous SSS measure increased by 24 and 8% the mortality risk of people aged 50–64 and ≥ 65 years, respectively, after adjustment for age, sex and marital status. The respective estimates for cardiovascular mortality were 36 and 11%. Adjustment for all covariates fully explained the association between SSS and cancer mortality, and partially the remaining associations. In people aged 50–64 years, SSS mediated to a varying extent the associations between objective SEP measures and all-cause mortality. In people aged ≥ 65 years, SSS mediated to a lesser extent these associations, and to some extent was associated with mortality independent of objective SEP measures. Nevertheless, in both age groups, wealth partially explained the association between SSS and mortality. In conclusion, SSS is a strong predictor of mortality at older ages, but its role in socioeconomic inequalities in mortality appears to be complex.

Background: A rapidly ageing population presents major challenges to health and social care services. Cross-country comparative studies on survival among older adults are limited. In addition, Japan, the country with the longest life expectancy, is rarely included in these cross-country comparisons. Objective: We examined the relative contributions of social and behavioural factors on the differences in survival among older people in Japan and England. Methods: We used data from the Japan Gerontological Evaluation Study (JAGES; n = 13,176) and the English Longitudinal Study of Ageing (ELSA; n = 5,551) to analyse all-cause mortality up to 9.4 years from the baseline. Applying Laplace regression models, the 15th survival percentile difference was estimated. Results: During the follow-up, 31.3% of women and 38.6% of men in the ELSA died, whereas 19.3% of women and 31.3% of men in the JAGES died. After adjusting for age and baseline health status, JAGES participants had longer survival than ELSA participants by 318.8 days for women and by 131.6 days for men. Family-based social relationships contributed to 105.4 days longer survival in JAGES than ELSA men. Fewer friendship-based social relationships shortened the JAGES men’s survival by 45.4 days compared to ELSA men. Currently not being a smoker contributed to longer survival for JAGES women (197.7 days) and ELSA men (46.6 days), and having lower BMI reduced the survival of JAGES participants by 129.0 days for women and by 212.2 days for men. Conclusion: Compared to participants in England, Japanese older people lived longer mainly because of non-smoking for women and family-based social relationships for men. In contrast, a lower rate of underweight, men’s better friendship-based social relationships, and a lower smoking rate contributed to survival among participants in England.

While the role of political factors on population health has recently received increasing attention, relatively little is known in that respect for oral health. We aimed to assess the influence of welfare state regimes on the variation in adult oral health between European countries, building on the existing literature by using a multilevel approach. Our analysis also explored how the oral health of people with different socioeconomic position was influenced by living in five different welfare state regimes. We analysed data from the Eurobarometer survey 2009. The main outcome was no functional dentition, defined as having fewer than 20 natural teeth. Age, gender, marital status, education and occupational social class were the individual-level explanatory variables, while welfare regimes, GDP per capita and GDP annual growth were the country-level variables. Multilevel logistic regression models were fitted with individuals nested within countries. Results revealed that country-level characteristics accounted for 8.1% of the variation in oral health. Adults in all welfare regimes were more likely to have poorer oral health than their counterparts in the Scandinavian regime, with those in Eastern countries being 6.94 (95% CI: 3.62-12.67) times as likely to lack a functional dentition as adults in Scandinavian countries. The variation at country-level reduced significantly when welfare regimes were introduced into the model (from 0.57 to 0.16; 72% reduction), indicating that welfare regime explained much of the variation in the outcome among European countries. Finally, adults with less education and lower occupational level were more likely to have no functional dentition, especially in the Eastern and Bismarckian welfare regimes.

Background: Periodontal intrabony defects are usually treated surgically with the aim to increase attachment and bone levels and reduce risk of progression. However, recent studies have suggested that a minimally-invasive non-surgical therapy (MINST) leads to considerable clinical and radiographic defect depth reductions in intrabony defects. The aim of this study is to compare the efficacy of a modified MINST approach with a surgical approach (modified minimally-invasive surgical therapy, M-MIST) for the treatment of intrabony defects. Methods: This is a parallel-group single-centre examiner-blind non-inferiority randomised controlled trial with a sample size of 66 patients. Inclusion criteria are age 25-70, diagnosis of periodontitis stage III or IV (grades A to C), presence of ≥1 ‘intrabony defect’ with probing pocket depth (PPD) >5 mm and intrabony defect depth ≥3mm. Smokers and patients who received previous periodontal treatment to the study site within the last 12 months will be excluded. Patients will be randomly assigned to either the modified MINST or the M-MIST protocol and will be assessed up to 15 months following initial therapy. The primary outcome of the study is radiographic intrabony defect depth change at 15 months follow-up. Secondary outcomes are PPD and clinical attachment loss (CAL) change, inflammatory markers and growth factors in gingival crevicular fluid, bacterial detection, gingival inflammation and healing (as measured by geometric/thermal camera imaging in a subset of 10 test and 10 control patients) and patient-reported outcomes. Discussion: This study will produce evidence about the clinical efficacy and potential applicability of a modified MINST protocol for the treatment of periodontal intrabony defects, as a less invasive alternative to the use of surgical procedures. Trial registration: This study was registered on clinicaltrials.gov NCT03797807 (date registered: 9 January 2019). Keywords: Periodontitis, intrabony defect, minimally-invasive, quality of life, bone

AIM: To assess the feasibility and acceptability of screening for alcohol misuse and delivering brief advice to eligible patients attending NHS dental practices in London.METHODS: A two-arm cluster randomized controlled feasibility trial was conducted. Twelve dental practices were recruited and randomized to intervention and control arms. Participants attending for a dental check were recruited into the study and were eligible if they consumed alcohol above recommended levels assessed by the AUDIT-C screening tool. All eligible participants were asked to complete a baseline socio-demographic questionnaire. Six months after the completion of baseline measures, participants were contacted via telephone by a researcher masked to their allocation status. The full AUDIT tool was then administered. Alcohol consumption in the last 90 days was also assessed using the Form 90. A process evaluation assessed the acceptability of the intervention.RESULTS: Over a 7-month period, 229 participants were recruited (95.4% recruitment rate) and at the 6 months follow-up, 176 participants were assessed (76.9% retention rate). At the follow-up, participants in the intervention arm were significantly more likely to report a longer abstinence period (3.2 vs. 2.3 weeks respectively, P = 0.04) and non-significant differences in AUDIT (44.9% vs. 59.8% AUDIT positive respectively, P = 0.053) and AUDIT C difference between baseline and follow-up (-0.67 units vs. -0.29 units respectively, P = 0.058). Results from the process evaluation indicated that the intervention and study procedures were acceptable to dentists and patients.CONCLUSIONS: This study has demonstrated the feasibility and acceptability of dentists screening for alcohol misuse and providing brief advice.

OBJECTIVES: The aim of this study was to assess whether traumatic dental injuries (TDI) were socially graded among children and adolescents in England, Wales and Northern Ireland, using nationally representative data from the Children's Dental Health Survey (CDHS) 2013. METHODS: This cross-sectional study used data from the Children's Dental Health Survey 2013 which was conducted among a nationally representative sample of schoolchildren in England, Wales and Northern Ireland. Children's family socioeconomic position (SEP) was measured through free school meal eligibility and relative area deprivation using the Indices of Multiple Deprivation. The analytical sample included 6707 schoolchildren aged 8, 12 and 15. Multiple logistic regression was used to model the associations between experience of TDI and the two markers of SEP, after adjusting for sex and age. RESULTS: The overall prevalence of traumatic dental injuries to permanent incisors was 9% (n = 590). There were no statistically significant associations between TDI and either SEP measure. Further subgroup analyses (n = 2650) showed also no significant associations between TDI and additional SEP markers (parental education and social class). The odds of having sustained a traumatic dental injury were higher for boys than for girls and were greater in older age groups. CONCLUSIONS: This study found no significant relationships between the experience of traumatic dental injuries and two markers of family socioeconomic position among children living in England, Wales and Northern Ireland. This implies that rather than specifically targeting the more deprived sectors of society, TDI prevention policies should use upstream public health strategies incorporating a whole-population approach.© 2016 John Wiley & Sons A/S.

Loneliness is a serious concern in aging populations. The key risk factors include poor health, depression, poor material circumstances, and low social participation and social support. Oral disease and tooth loss have a significant negative impact on the quality of life and well-being of older adults. However, there is a lack of studies relating oral health to loneliness. This study investigated the association between oral health-related quality of life (through the use of the oral impact on daily performances—OIDP—measure) and loneliness amongst older adults living in England. Data from respondents aged 50 and older from the third (2006–2007) and fifth (2010–2011) waves of the English Longitudinal Study of Ageing were analyzed. In the cross-sectional logistic regression model that adjusted for socio-demographic, socio-economic, health, and psychosocial factors, the odds of loneliness were 1.48 (1.16–1.88; p

Objective To assess whether short-term changes in income (IC) in adulthood were associated with self-rated oral health (SROH) and chewing difficulties (CD). Methods Secondary analysis of a longitudinal study in Florianopolis, Southern Brazil (EpiFloripa); a total of 1720 adults participated in 2009 and 1223 in 2012. Logistic regression analysed the variation of SROH and CD according to short-term changes in income (IC) groups (‘high income-stable’, ‘increased income’, ‘decreased income’ and ‘low income-stable’) and adjusted for covariates (age, sex, marital status, skin colour, self-reported number of teeth and education). Results After adjusting for covariates, participants in the ‘decreased income’ were more likely to have poor SROH and CD than those at the ‘high income-stable’ group (OR: 1.78, 95% CI: 1.23, 2.58; OR: 2.76, 95% CI: 1.61, 4.74, respectively). Significant differences were also found between the ‘low income-stable’ and ‘high income-stable’ groups, but these differences were explained when adjusted for potential confounders. There were no significant differences in SROH and CD between the ‘increased income’ and the ‘high income-stable’ groups. Conclusions Overall, SROH and CD were adversely influenced by negative changes in income during adulthood in a short period of 3 years.

OBJECTIVE: To assess the extent to which behavioural factors, including those related to dental care, account for oral health inequalities in different European welfare state regimes. METHODS: Data from the Eurobarometer 2009 survey were analysed. Nationally representative samples of dentate adults aged ≥45 years (n = 9979) from 21 European countries classified into the five welfare regimes (Scandinavian, Anglo-Saxon, Bismarckian, Southern, Eastern) were considered. Inequalities in no functional dentition (having

Summary Background Chronic inflammation is believed to be a major mechanism underlying the pathophysiology of type 2 diabetes. Periodontitis is a cause of systemic inflammation. We aimed to assess the effects of periodontal treatment on glycaemic control in people with type 2 diabetes. Methods In this 12 month, single-centre, parallel-group, investigator-masked, randomised trial, we recruited patients with type 2 diabetes, moderate-to-severe periodontitis, and at least 15 teeth from four local hospitals and 15 medical or dental practices in the UK. We randomly assigned patients (1:1) using a computer-generated table to receive intensive periodontal treatment (IPT; whole mouth subgingival scaling, surgical periodontal therapy [if the participants showed good oral hygiene practice; otherwise dental cleaning again], and supportive periodontal therapy every 3 months until completion of the study) or control periodontal treatment (CPT; supra-gingival scaling and polishing at the same timepoints as in the IPT group). Treatment allocation included a process of minimisation in terms of diabetes onset, smoking status, sex, and periodontitis severity. Allocation to treatment was concealed in an opaque envelope and revealed to the clinician on the day of first treatment. With the exception of dental staff who performed the treatment and clinical examinations, all study investigators were masked to group allocation. The primary outcome was between-group difference in HbA 1c at 12 months in the intention-to-treat population. This study is registered with the ISRCTN registry, number ISRCTN83229304. Findings Between Oct 1, 2008, and Oct 31, 2012, we randomly assigned 264 patients to IPT (n=133) or CPT (n=131), all of whom were included in the intention-to-treat population. At baseline, mean HbA 1c was 8·1% (SD 1·7) in both groups. After 12 months, unadjusted mean HbA 1c was 8·3% (SE 0·2) in the CPT group and 7·8% (0·2) in the IPT group; with adjustment for baseline HbA 1c , age, sex, ethnicity, smoking status, duration of diabetes, and BMI, HbA 1c was 0·6% (95% CI 0·3–0·9; p Interpretation Compared with CPT, IPT reduced HbA 1c in patients with type 2 diabetes and moderate-to-severe periodontitis after 12 months. These results suggest that routine oral health assessment and treatment of periodontitis could be important for effective management of type 2 diabetes.

Background Studies in high-income countries have reported associations between tooth loss and hypertension. There is however a lack of evidence on this association from South Asian countries especially India. The current study aimed to assess the association between self-reported tooth loss and hypertension in a primarily rural middle-aged and older Indian population. Methods A secondary analysis of cross-sectional data from the Longitudinal Ageing Study of India – pilot survey was conducted on 1,486 adults aged 45 years and above from four states of India. The primary outcome was self-reported hypertension and the main explanatory variable was self-reported tooth loss. Multivariable logistic regression models estimated the association between hypertension and tooth loss after controlling for confounders including age, sex, marital status, area of residence, educational attainment, tobacco use, alcohol use, physical activity, and self-reported diabetes. Results Compared to those without any tooth loss, individuals with partial tooth loss had 1.62 times (95% CI: 1.12-2.35) higher odds of being hypertensive after adjustment of confounders including age, sex, marital status, area of residence, educational attainment, tobacco use, alcohol use, physical activity, and self-reported diabetes. The crude significant association (OR: 2.54; 95% CI: 1.50-4.29) between edentulousness and hypertension became nonsignificant and attenuated after adjustment of potential confounders (fully adjusted model OR: 1.33; 95% CI: 0.72-2.44). Conclusion Partial tooth loss was associated with a higher probability of hypertension among dentate middle-aged and older adults in four states of India.

Oral health-related quality of life (OHRQoL) measures should be tested for responsiveness to change if they are to be used as outcomes in randomized clinical trials.To assess the responsiveness of the Brazilian ECOHIS (B-ECOHIS) to dental treatment of dental caries.One hundred parents of 3- to 5-year-old children completed the B-ECOHIS prior to their children's treatment and 7-14 days after completion of treatment. The post-treatment questionnaire also included a global transition judgment that assessed parent's perceptions of change in their children's oral health following treatment. Change scores, longitudinal construct validity, standardized effect sizes (ES) and standardized response mean (SRM) were calculated.Improvements in children's oral health after treatment were reflected in mean pre- and post-treatment B-ECOHIS scores. They declined considerably significantly from 17.4 to 1.6 (P 0.0001), as did the individual domain scores (P 0.0001). There were significant differences in the pre- and post-treatment scores of children who reported little improvement (P 0.0001) as well as in those who reported large improvements (P 0.0001). The ES and SRM based on change scores mean for total scores and for categories of global transitions judgments were large.Dental treatment resulted in significant improvement of the preschool children's OHRQoL. The B-ECOHIS is responsive.

© 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd. Objective To explore the association of depression and anxiety with two oral health outcomes, dental caries and periodontal disease and assess possible mediators for any of the associations. Methods Secondary analysis of the Finnish Health 2000 Survey. Depression was assessed with Beck's Depression Inventory and anxiety with Composite International Diagnostic Interview. Number of decayed teeth included carious lesions reaching dentine; periodontal disease was number of teeth with periodontal pockets of 4 mm or deeper. Third molars were excluded. The association of mental disorders and oral health was tested in regression models adjusted for confounders and potential mediators. Results Depression was associated with number of decayed teeth only among 35- to 54-year-olds. The association between anxiety and the number of decayed teeth was not statistically significant. Depression and periodontal pocketing were not significantly associated. Conclusion Depression was significantly associated with number of decayed teeth only among participants aged 35-54 old and not with other age groups. Neither depression nor anxiety was significantly related to periodontal disease.
