Ismeretes, hogy az utóbbi évtizedekben lényegesen javult az európai gyermekek orális egészsége, mind a tej-, minda maradó fogak vonatkozásában csökkent a caries előfordulása. Ugyanakkor néhány kelet- és közép-európai országbanmég mindig óriási teher a szájüregi betegségek nagy száma.Jelen közlemény célja a hazai 5–6 és 12 éves gyermekek caries előfordulásának ismertetése, a fogszuvasodás trendjénekhosszú távon, 30 éven át történő nyomon követése a hazai pathfinder vizsgálatok tükrében. Az egymást követőreprezentatív keresztmetszeti vizsgálatokat 1985 és 1917 között (1991, 1996, 2001, 2018, 2013) a WHO pathfindermethodology szerint végeztük. Az epidemiológiai adatgyűjtés vizuális klinikai vizsgálatokkal történt.Ezen időszak alatt az 5–6 éves ép fogú gyerekek aránya 30%-ról 2017-ben 43,8%-ra nőtt, a vidéki helyszíneken mindigalacsonyabb értékekkel. 2017-ben a városi érték 49,9%, a vidéki pedig 34,6% (p < 0,001), a dmft országos átlagértéke3,5. A tej frontfogak caries előfordulása az évek során kissé csökkent, legutóbb 21,6% volt. A 12 évesek caries frekvenciájaés intenzitása folyamatosan csökkenő trendet mutat, az 1985-ben mért 92,5%-ról 55,3%-ra, illetve 5,0 DMFT-ről2,3-ra javult (p < 0,001). Jelentős eredmény, hogy az ép fogazattal rendelkező gyerekek aránya 7,5%-ról 44,7%-ra nőtt.Azonban az utóbbi évtizedben a javulás intenzitása lassult, s egyidejűleg a D komponens értékének növekedése figyelhetőmeg. A Significant Caries Index (SIC index) értéke 5–6 éveseknél 8,43, 12 éveseknél 5,23. Az eredmények azt tükrözik,hogy országosan változatlanul nagy területi különbségek vannak a városi és a hátrányosabb helyzetben lévő vidékigyerekek orális egészségi állapotában. A care index 30%-os ellátottsági szintet jelez, tehát nagy a kezelési szükséglet.A legutóbbi adatok alapján megállapítható, hogy Magyarország az 5–6 évesek vonatkozásában a WHO/FDI 2000-rekitűzött globális céljait sem érte még el. A 12 éveseknél a globális célkitűzések megvalósultak ugyan, de az európaiaknem. Irreálisnak tűnik, hogy hazánk megfeleljen a 2020-as WHO/FDI/IADR elvárásoknak. Sürgető népegészségügyifeladat országos komplex prevenciós programok szervezése, konkrét fogászati célkitűzések, módszerek és feladatokmegjelölésével. Élvezzen prioritást a széles körű minőségi szájápolás, a fluoridok effektív alkalmazása és az iskolafogászatrevitalizálása.

The intention of the study was to evaluate whether Sub-Saharan schoolteachers may play a key role in oral health promotion of primary schoolchildren, particularly in terms of prevention of HIV/AIDS-related oral health problems.The study examined the level of knowledge about oral disease and the prevention of HIV/AIDS oral lesions amongst schoolteachers of Tanzania and Burkina Faso, identified their sources of information, and evaluated their ability for HIV/AIDS intervention. A multi-centre cross-sectional study was implemented in the two Sub-Saharan African countries. Participants comprised primary school teachers selected by stratified cluster sampling: 261 teachers from Tanzania and 313 teachers from Burkina Faso. All participants completed a structured questionnaire prepared for self-administration. The questions were designed from a standardised questionnaire developed by the World Health Organization.Most teachers knew about the principal causes of the major oral diseases and the means of disease prevention. Nearly all teachers (95.6%) were aware of HIV/AIDS and they knew (92.3%) a virus was the direct cause of AIDS. Teachers were well informed of the general symptoms of HIV/AIDS, although oral symptoms were mentioned less often. In all, 17.6% of schoolteachers reported that children suffering from HIV/AIDS were found in their classes and 10.3% of teachers were conscious of students receiving anti-retroviral therapy (ART). Knowledge about the disease seemed to reflect mass media as a source, while teacher colleagues and health personnel played a somewhat lesser role in communication. In total, 83.2% emphasised that they should teach children about HIV/AIDS and the mouth. Schoolteachers from Tanzania (70.5%) were more often engaged in classroom-based oral health education than were the Burkinabe teachers (53.9%).The study confirms that schoolteachers may be a relevant source in the fight against HIV/AIDS among children. However, they would benefit from interaction with health personnel.

1. To assess the oral health status and health behaviour of 5- to 6-year-oldchildren and the influence of socio-behavioural factors on oral health among children, and 2. evaluate dental knowledge and attitudes related to oral health promotion of children among mothers and schoolteachers in Palestine.This cross-sectional survey was carried out in 2017, and recruited samples of children (n = 3939, 53.8% boys, 44.8% girls) from 61 primary schools, their mothers and schoolteachers (n = 53). Participants were selected randomly by multistage stratified cluster sampling. Calibrated dentists performed oral examinations of 5- to 6-year-old schoolchildren based on WHO criteria. Mothers and teachers completed WHO self-administrated questionnaires to assess children's oral health behaviour, as well as their knowledge and attitudes towards children's dental care.Caries prevalence of primary teeth was 83.4% and caries experience was high (dmf-s = 11.17). One-fourth of children suffered from pain or discomfort from teeth, and 57.7% of children had seen a dentist within the past 12 months, frequently due to pain or problems. Consumption of sugars was frequent and only 19.7% brushed their teeth every day. Neglect of dental visits, infrequent toothbrushing, being a child from families of urban settings and high socioeconomic status were greatly affected by caries. Mothers and schoolteachers had most ly positive attitudes towards school-based oral health care. However, the availability of dental health education materials was extremely low.The establishment of school-based oral health programmes, including effective use of toothpaste containing fluoride for caries prevention, is greatly needed to improve the oral health of Palestinian children. The introduction of fluoridated school milk is highly recommended. The establishement of school programmes should encompass active involvement of schoolteachers and mothers to promote the development of healthy lifestyles and sustainable oral health behaviours among schoolchildren. Provision of materials for health education by schoolteachers and mothers is urgent ly needed.

Oral/dental healthcare delivery in the post-pandemic era will be different, with challenges to overcome and positive opportunities to take. Managing the needs, wants and expectations of all stakeholders must be communicated and actioned effectively, moving forwards. It is the responsibility of all stakeholders to work together to help provide high quality, evidence-based pragmatic oral healthcare delivery for the future. Patient-focused, team-delivered, minimum intervention oral healthcare (MIOC) is applicable to all patients at all stages of their lives and underpins long-term delivery of better oral and systemic health to all. Guidance, peer-support, whole -team training along with agile commissioning and suitable incentivisation will need to support the paradigm shift to prevention-based MIOC clinical practice .

Main topics The oral health impact of social determinants affecting all population groups is known universally. Variations exist by income, education, occupation, ethnic minority groups, environmental conditions, gender, families and children, and generations spanning from children to older people. Inequality in oral health tends to last from early childhood to older age. Social diversities in oral health and general health are comparable due to shared causal mechanisms. The financial burden related to use of private dental health services plays a powerful role in creation of inequality. Structural, psychosocial and political determinants are drivers in creation of inequalities. WHO give emphasis to intervention against social determinants in health; inequalities in health are unfair and can be reduced by the right mix of government policies.

Improved oral health of children is noted in most Western countries, but this coincides with a high burden of oral disease in several countries of Central and Eastern Europe. The purpose of the present study was to describe the current level of dental caries in Hungarian children aged 5, 6, and 12 years and to assess the long-term trends in caries over 30 years. In addition, the report aims to highlight the oral health habits of 12-year-old children in Hungary.A representative survey was undertaken in 2016-2017 according to the WHO Pathfinder methodology, which was also applied in previous national oral health surveys of 1985, 1991, 1996, 2001, and 2008. Children of 5-6 and 12 years were sampled systematically in all surveys over 30 years. Data were gathered through clinical examinations and a questionnaire used for 12-year-olds.In 2016-2017, 42.6% of 5- to 6-year-olds were caries free, with the proportion lower in rural than urban settings. Approximately four primary teeth were affected by caries among children aged 5-6 years. Most of the disease burden consisted of untreated caries. Caries experience was higher for children living in rural areas. At age 12, about two permanent teeth suffered from caries, and the D-component of the caries index was high. The percentage of caries-free 6-year-olds grew from 9% in 1985 to 42.6% in 2016-2017. In 1985, 12-year-olds had on average 5 teeth affected by caries, and after 30 years, the level of caries declined to 2.3 DMFT in 2016-2017. The responses to the questionnaire showed that 11.9% of 12-year-olds visited the dentist because of oral pain or discomfort and 40.5% were dissatisfied by the appearance of their teeth. About 40% of children consumed soft drinks or sweets/candy, several times a day.Hungary has not yet achieved the WHO goals for children aged 5-6. While Hungary accomplished the WHO goal for oral health of 12-year-olds by the year 2000, it is seems unrealistic for the country to achieve the WHO goal for 12-year-olds by the year 2020. For better oral health of children, strong emphasis should be given to population-directed oral disease prevention, including the reduction of sugar consumption and implementing public health programmes for the effective use of fluoride.

The first large-scale epidemiological survey on dental caries in Slovenia was conducted in 1987 and repeated in 1993, 1998, 2003, 2008, 2013 and 2017, using the same methodology. The aim of the study was to examine the trend of caries in 12-year-olds in Slovenia during a 30-year time period. The changes over time in caries experience were compared with disease trends observed in other European countries. Study Populations and Methods: The WHO National Oral Health Pathfinder Survey was applied in all seven surveys (1987-2017). The surveys were carried out in all nine geographical regions of Slovenia. For each subject, the caries experience and presence of sealants were recorded.The mean DMFT of 12-year-olds decreased significantly from 5.1 in 1987 to 1.5 in 2017 (p0.0001). The percentage of persons with sealed teeth increased from 6% in 1987 to 94% in 2017, and the percentage of caries-free persons increased from 6% to 42%.The implementation of a nation-wide preventive programme was determined to significantly contribute to the effective control of caries and continuously improve the oral health of Slovenian children. In an international perspective, the Slovenian achievements in disease prevention in terms of caries prevalence reduction may be important for other countries of the region.

Early Childhood Caries (ECC) is prevalent around the world, but in particular the disease is growing rapidly in low- and middle-income countries in parallel with changing diet and lifestyles. In many countries, ECC is often left untreated, a condition which leads to pain and adversely affects general health, growth and development, and quality of life of children, their families and their communities. Importantly, ECC is also a global public health burden, medically, socially and economically. In many countries, a substantial number of children require general anaesthesia for the treatment of caries in their primary teeth (usually extractions), and this has considerable cost and social implications. A WHO Global Consultation with oral health experts on "Public Health Intervention against Early Childhood Caries" was held on 26-28 January 2016 in Bangkok (Thailand) to identify public health solutions and to highlight their applicability to low- and middle-income countries. After a 3-day consultation, participants agreed on specific recommendations for further action. National health authorities should develop strategies and implement interventions aimed at preventing and controlling ECC. These should align with existing international initiatives such as the Sixtieth World Health Assembly Resolution WHA 60.17 Oral health: action plan for promotion and integrated disease prevention, WHO Guideline on Sugars and WHO breastfeeding recommendation. ECC prevention and control interventions should be integrated into existing primary healthcare systems. WHO public health principles must be considered when tackling the effect of social determinants in ECC. Initiatives aimed at modifying behaviour should focus on families and communities. The involvement of communities in health promotion, and population-directed and individual fluoride administration for the prevention and control of ECC is essential. Surveillance and research, including cost-effectiveness studies, should be conducted to evaluate interventions aimed at preventing ECC in different population groups.

Objectives The WHO World Health Assembly established in 2007 a Resolution (WHA60.17) on oral health, which called upon countries to ensure that public health actions for disease prevention and health promotion are established. The objective of the present survey undertaken 10 years later (2017‐2018) was to measure the application of such programmes for key population age groups in low‐, middle‐ and high‐income countries. Methods Oral health focal points of ministries of health worldwide (n = 101) answered a structured questionnaire on existing national oral health systems and the actual public health activities. The response rate was 58.4%. The questionnaire was used to collect information about structural factors, country workforce, financial models, provision of preventive services and promotion for oral health, school health programmes, administration of fluoride, national oral health targets and oral health surveillance. The countries were classified by national income for analysis of data. Results Coverage of population groups by primary oral health care and emergency care varied by national income. The gap between countries in delivery of preventive care was strong since low‐income countries less often reported preventive activities than middle‐income countries and particularly when compared to high‐income countries. School oral health programmes were less frequent in low‐income than other countries. Moreover, population methods of fluoridation and use of fluoridated toothpaste were unusual in low‐income countries. Health education, mass communication and community events were often essential elements in health promotion. In disease prevention, many countries considered the link between oral health and general health conditions and intervention towards shared risk factors of NCDs. The health concern for the consumption of tobacco, unhealthy diet and sugars was particularly emphasized by high‐income countries but less highlighted by low‐income countries. Finally, while national oral health targets for children and surveillance systems were frequently reported by countries, similar systems for adolescents, adults and older people were rare. Conclusions The inequities between countries in oral disease prevention and health promotion were substantial. Limited financial resources for preventive care and health promotion; inadequate workforce for oral health, and insufficient coverage in primary health care were observed in low‐resource countries. The results of the survey demonstrate the need for building effective oral health systems oriented towards oral disease prevention and health promotion.

This article provides an example of interprofessional collaboration for policy development regarding environmental global health vis-a-vis the Minamata Convention on Mercury. It presents an overview of mercury and mercury-related environmental health issues; public policy processes and stakeholders; and specifics including organized dentistry's efforts to create global policy to restrict environmental contamination by mercury. Dentistry must participate in interprofessional collaborations and build on such experiences to be optimally placed for ongoing interprofessional policy development. Current areas requiring dental engagement for interprofessional policy development include education, disaster response, HPV vaccination, pain management, research priorities, and antibiotic resistance.

This report intends to review the global burden of oral disease among older people and to examine their oral health needs. The evidence on the inter-relationships between poor oral health conditions of older people, general health and quality of life is highlighted. Finally, WHO strategies to improve oral health of older people are reviewed.The information relevant to this review was extracted from the WHO Global Oral Health Data Bank, the PubMed database, and the Cochrane Library. Surveys were carried out according to the criteria recommended by the WHO epidemiological manual Oral Health Surveys - Basic Methods. In addition, global data were sought on coverage of oral health care among older people. Finally, WHO policy documents on health care for aged people were gathered through the WHO website.Across the globe, many older people suffer from oral pain or discomfort. Poor oral health during old age is mostly manifest in high caries experience, high prevalence rates of advanced periodontal disease, severe tooth loss, dry mouth, and oral pre-cancer/cancer. In both developing and developed countries, the burden of disease is particularly high among underprivileged and disadvantaged older people. In numerous countries, high proportions of the aged population are not covered by primary oral health care; this is mainly the case in low and middle income countries due to a critical shortage of dentists.In 2015, the WHO published the World Report on Ageing and Health, which outlines a framework for action to foster healthy ageing. The policies are highly relevant to the improvement of oral health. Transformation of oral health systems away from a disease-based curative model and towards disease prevention, as well as the provision of older-person-centred integrated care are required. Moreover, wide-ranging public health action on ageing is urgently needed.

Background Asthma in paediatric populations is one of the highest public health concerns. In this study of children and adolescents, we hypothesized that low levels of physical activity (PA) would show associations with asthma that vary by asthma outcome. The objective was to assess whether PA was associated with ever asthma and/or current asthma. Methods Analyses were based on 4824 Danish schoolchildren aged 11–15 years old (48.7% boys) participating in the HBSC survey. The study variables were (1) physician-diagnosed asthma (ever asthma) and (2) physician-diagnosed asthma plus wheezing and/or physician or hospital consultation for wheezing (current asthma). Associations with PA by gender were analysed with multivariate logistic regression using the “variance covariance (vce) cluster” method. Results The prevalence of ever asthma was 14.3% (boys) and 12.8% (girls), and that of current asthma was 6.8% (boys) and 7.0% (girls). Boys with current asthma showed important differences in low and high PA. We found inverse associations between low PA and ever asthma, odds ratio [95% confidence interval] male: .55 [.30; .99] and female: .47 [.24; .93], and current asthma, male: .27 [.12; .60] (P linear trend = .007) and female: .32 [.11; .94]. Conclusions The lowest activity levels showed significant inverse associations with asthma, regardless of the definition. For boys, the more stringent (current asthma) of the two paediatric asthma definitions revealed a significant trend with PA, and the direction of associations shifted to positive as weekly PA increased.

Background Political conflicts in the Palestinian Territories (PT) have resulted in systematic deterioration of socio-economic conditions and health. The World Health Organization (WHO) has emphasised the negative impacts of social crisis on children' oral health and quality of life. Objectives To assess the prevalence and trends in dental caries and poor gingival health of schoolchildren in the PT through the scholastic years 1998/1999 to 2012/2013. Methods This is a retrospective study. Prevalence data on dental caries of primary and permanent dentitions among children 6, 12 and 16 years of age were gathered from annual oral health reports of the School Dental Health Programme (SDHP)-Ministry of Health. Caries was recorded according to WHO methods and criteria. Decayed, missing and filled teeth indices for primary (dmft) and permanent (DMFT) teeth were calculated. Gingival health status was examined according to the Community Periodontal Index (scores 1 and 2). Statistical analysis used SPSS. Results In 2012/2013, dental caries prevalence rates and the index scores among schoolchildren were as follows, respectively: 56.4% and 2.7 dmft at age 6; 42.0% and 1.4 DMFT at age 12; and 38.7% and 1.7 DMFT at age 16. For all age groups, the d/D-component of the caries indices was high. Trends of dental-caries prevalence, caries experience and gingival bleeding were fairly constant over time from 1998/1999. Conclusion The SDHP was established in order to prevent and control oral diseases among schoolchildren in the PT. The Programme is fairly passive and the survey indicates an urgent need for reorientation of activities towards population-based prevention and health promotion. The application of the WHO Health Promoting Schools concept is highly recommended.

The burden of oral disease is high in populations across the world. This is because of high consumption of free sugars. The WHO Guideline on Sugars Intake for Adults and Children recommended limiting free sugars to no more than 5% energy intake to protect oral health throughout the life-course. The objectives of this paper are to consider the implications of the Guideline for dental health practice and to advocate use of the common risk factor approach when providing dietary advice. As part of a broad range of actions needed to reduce free sugars intake, improved education for dental health professionals and supporting patients to eat less free sugars are key actions for the dental profession. All dental health professionals should have the skills and confidence to provide their patients with healthier eating advice, including how to limit free sugars intake. It is therefore important that dental health professionals receive adequate education in diet and nutrition, and there is a need for dental educational regulating bodies to define the content of the dental curriculum with respect to nutrition. All patients, or their parents or carers, should receive dietary advice to reduce free sugars within the context of a healthy diet for the prevention of all NCDs. Dietary advice should: (i) focus on reducing the amount of free sugars consumed; (ii) be tailored according to the patient's body mass status (eg underweight, overweight, normal weight); (iii) encourage the consumption of fresh fruits and vegetables, nuts, seeds, and wholegrain starch-rich foods; (iv) discourage the consumption of foods high in saturated fat and salt; and (v) discourage the consumption of all drinks containing free sugars. The dental health professional has an opportunity to support patients to reduce their intake of free sugars-such advice and support will have positive impacts beyond the mouth.

Around the globe many people are suffering from oral pain and other problems of the mouth or teeth. This public health problem is growing rapidly in developing countries where oral health services are limited. Significant proportions of people are underserved; insufficient oral health care is either due to low availability and accessibility of oral health care or because oral health care is costly. In all countries, the poor and disadvantaged population groups are heavily affected by a high burden of oral disease compared to well-off people. Promotion of oral health and prevention of oral diseases must be provided through financially fair primary health care and public health intervention. Integrated approaches are the most cost-effective and realistic way to close the gap in oral health between rich and poor. The World Health Organization (WHO) Oral Health Programme will work with the newly established WHO Collaborating Centre, Kuwait University, to strengthen the development of appropriate models for primary oral health care.

Background: The World Health Organization (WHO) emphasizes that dental caries is a severe public health problem across the world. The current global and regional patterns of dental caries reflect distinct risk profiles of countries which relate to the structure of the society, living conditions, lifestyles, and the existence of preventive oral health programmes. Research conducted in high income countries documents that systematic use of fluoride reduces the burden of dental caries; such research is scarce in low and middle income countries.Objectives: This article reviews the evidence on effective use of fluoride, highlights the public health approach to fluoridation, and clarifies how automatic fluoridation contributes to breaking social inequities in dental caries.Data collection: Scientific publications on fluoride administration stored in PubMed/Medline and caries data from the WHO databank.Outcome: Dental caries identified from national surveys or country relevant data; extraction of scientific reports is based on their public health relevance.Conclusions: The article outlines the history of fluoridation programmes and describes the sound evidence on automatic fluoridation through water, salt and milk, or from the use of high quality fluoridated toothpastes (1000-1500 ppm F). The experiences from the implementation of programmes in various countries are discussed and the potential for breaking the social inequalities in the burden of dental caries is clarified. Finally, the role of WHO in the development and implementation of fluoridation schemes is explained; WHO technical assistance in the outcome evaluation and assessment of fluoride exposure is enlightened.

Chronic diseases are accelerating globally, advancing across all regions and pervading all socioeconomic classes. Unhealthy diet and poor nutrition, physical inactivity, tobacco use, excessive use of alcohol and psychosocial stress are the most important risk factors. Periodontal disease is a component of the global burden of chronic disease, and chronic disease and periodontal disease have the same essential risk factors. In addition, severe periodontal disease is related to poor oral hygiene and to poor general health (e.g. the presence of diabetes mellitus and other systemic diseases). The present report highlights the global burden of periodontal disease: the ultimate burden of periodontal disease (tooth loss), as well as signs of periodontal disease, are described from World Health Organization (WHO) epidemiological data. High prevalence rates of complete tooth loss are found in upper middle-income countries, whereas the tooth-loss rates, at the time of writing, are modest for low-income countries. In high-income countries somewhat lower rates for edentulism are found when compared with upper middle-income countries. Around the world, social inequality in tooth loss is profound within countries. The Community Periodontal Index was introduced by the WHO in 1987 for countries to produce periodontal health profiles and to assist countries in the planning and evaluation of intervention programs. Globally, gingival bleeding is the most prevalent sign of disease, whereas the presence of deep periodontal pockets (≥6 mm) varies from 10% to 15% in adult populations. Intercountry and intracountry variations are found in the prevalence of periodontal disease, and these variations relate to socio-environmental conditions, behavioral risk factors, general health status of people (e.g. diabetes and HIV status) and oral health systems. National public health initiatives for the control and prevention of periodontal disease should include oral health promotion and integrated disease-prevention strategies based on common risk-factor approaches. Capacity building of oral health systems must consider the establishment of a financially fair service in periodontal care. Health systems research is needed for the evaluation of population-oriented oral health programs.

Health care systems are essential for promoting, improving and maintaining health of the population. Through an efficient health service, patients can be advised of disease that may be present and so facilitate treatment; risks factors whose modification could reduce the incidence of disease and illness in the future can be identified, and further, how controlling such factors can contribute to maintain a good quality of life. In developed countries, clinics or hospitals may be supported by health professionals from various specialties that allow their cooperation to benefit the patient; these institutions or clinics may be equipped with the latest technical facilities. In developing countries, health services are mostly directed to provide emergency care only or interventions towards certain age group population. The most common diseases are dental caries and periodontal disease and frequently intervention procedures aim, at treating existing problems and restore teeth and related structure to normal function. It is unfortunate that the low priority given to oral health hinders acquisition of data and establishment of effective periodontal care programmes in developing countries but also in some developed countries where the periodontal profile is also less than satisfactory. Despite the fact that in several developed countries there are advanced programmes oriented to periodontal disease treatments, the concern is related to the lack of preventive oriented treatments. According to data available on periodontal status of populations from developed countries, despite the number of dentists and trained specialists, dental health professionals do not presently meet adequately the need for prevention, focusing mainly on curative care. The need for strengthening disease prevention and health promotion programmes in order to improve oral health conditions and particularly periodontal status in the majority of countries around the world is evident. Unfortunately, in many countries, the human, financial and material resources are still insufficient to meet the need for oral health care services and to provide universal access, especially in disadvantaged communities, in both developing and developed countries. Moreover, even though the most widespread illnesses are avoidable, not all population groups are well informed about or able to take advantage of the proper measures for oral health promotion. In addition, in many countries, oral health care needs to be fully integrated into national or community health programmes. Improving oral health is a very challenging objective in developing countries, but also in developed countries, especially with the accelerated aging of the population now underway and intensifying over the coming years.

Clinical and public health research data have shown that a number of individual, professional and community health measures may be valuable in preventing the major oral diseases. The fundamental gap in knowledge, however, is not confined to ‘what to do’ but rather ‘how’ to translate the scientific findings into effective and sustainable programs for groups and populations. The advances in oral health science have not yet benefitted the poor and disadvantaged population groups around the world to the fullest extent possible and this has led to inequalities in periodontal health as well as in other chronic diseases. Research on the causative role of tobacco use in periodontal disease is strong because of the fact that tobacco-induced disease ultimately may lead to the loss of teeth. Studies also indicate that wound healing may be negatively affected by the use of tobacco. Likewise, research has shown that extreme use of alcohol, poor diet and nutrition, and psychological stress all have negative effects on periodontal health. Research on sociobehavioral risk factors has great implication to prevent periodontal disease. The case for tobacco is illustrated in this report. The global exposure to tobacco use in adults and adolescents is outlined. Because of the global Framework Convention for Tobacco Control (2003), the solid research on the harmful effect of tobacco is now being widely used for public health. The importance of tobacco prevention within the context of health-promoting schools is emphasized. Research on other population-directed strategies and their implications on public health would be instrumental to integrated prevention of chronic disease and periodontal disease. Community interventions and delivery of preventive oral care by oral health services may have positive outcomes for periodontal health but periodontal research needs to be further strengthened by the provision of sound evidence. It is somewhat remarkable that research on true population-directed actions in prevention of periodontal disease is most unusual. The high need for reorientation of periodontal research toward public health is discussed in this report as well as the responsibilities of oral health organizations, research institutions and health authorities.

Chronic diseases are a growing burden to people, to health-care systems and to societies across the world. The rapid increase in the burden of chronic diseases is particularly prevalent in the developing countries. Periodontal disease is one of the two most important oral diseases contributing to the global burden of chronic disease. In addition to social determinants, periodontal health status is related to several proximal factors. Modifiable risk factors, such as tobacco use, excessive alcohol consumption, poor diet and nutrition, obesity, psychological stress and insufficient personal/oral hygiene, are important and these principal risk factors for periodontal disease are shared by other chronic diseases. The present monograph is devoted to the existing evidence on the practice of public health related to periodontal health. Public health is defined as the process of mobilizing and engaging local, national and international resources to assure that people can be healthy. Social determinants of health, environmental hazards and unhealthy lifestyles are prioritized in modern public health-care. Disease prevention and health promotion are cornerstones in actions for public health. This volume of Periodontology 2000 is entitled ‘Periodontal health and global public health’; the 12 articles of this volume discuss different aspects of this statement. It covers a range of subjects from public health issues to patient care. This monograph intends to stimulate community action research in the field of periodontology in order to help the development of appropriate public health intervention and relevant surveillance programs. It also expects to stimulate health authorities and professional organizations to initiate and support actions to promote periodontal health in their respective countries.

This paper describes tools used to measure periodontal diseases and the integration of these tools into surveillance systems. Tools to measure periodontal diseases at the surveillance level have focussed on current manifestations of disease (e.g. gingival inflammation) or disease sequelae (e.g. periodontal pocket depth or loss of attachment). All tools reviewed in this paper were developed based on the state of the science of the pathophysiology of periodontal disease at the time of their design and the need to provide valid and reliable measurements of the presence and severity of periodontal diseases. Therefore, some of these tools are no longer valid. Others, such as loss of periodontal attachment, are the current de-facto tools but demand many resources to undertake periodical assessment of the periodontal health of populations. Less complex tools such as the Community Periodontal Index, have been used extensively to report periodontal status. Laboratory tests for detecting putative microorganisms or inflammatory agents present in periodontal diseases have been used at the clinical level, and at least one has been tested at the population level. Other approaches, such as self-report measures, are currently under validation. In this paper, we do not review indices designed to measure plaque or residual accumulation around the tooth, indices focussed only on gingival inflammation or radiographic approaches with limited applicability in surveillance systems. Finally, we review current case-definitions proposed for surveillance of periodontal disease severity.

Periodontal diseases are highly prevalent, particularly amongst socially disadvantaged populations, impact on quality of life and are costly to treat. Clinical treatments and chairside preventive approaches alone will never adequately address this problem. Indeed in many parts of the developing world clinical care and chairside prevention are both unaffordable and inappropriate for the control of periodontal diseases. A paradigm shift away from the individualized treatment approach to a population public health model is needed to promote periodontal health and, in particular to address social inequalities in periodontal status. Public health measures need to focus on the underlying determinants of periodontal diseases. Poor hygiene, tobacco use, psychosocial factors and related systemic diseases are the main risk factors for periodontal diseases. Public health interventions need to tackle these factors but also must recognize and act upon the distal underlying influences that determine and pattern these identified risks. Recognition also needs to be placed on the interlinking and common risk factors shared by periodontal diseases and other chronic conditions. A complementary range of public health policies acting at local, regional, national and international levels need to be implemented to achieve sustainable improvements in oral health. To be effective these policies need to link across the broader public health agenda and require public engagement and support. Clinicians, public health practitioners, commercial organizations and professional groups all have an important role to play in promoting periodontal health.

Dental caries is the most prevalent chronic disease affecting human populations around the world. It is recognized that fluoride plays a significant role in dental caries reduction. Meanwhile, several low- and middle-income countries of Asia have not yet implemented systematic fluoride programs; contributing factors relate to misconceptions about the mechanisms of fluoride, low priority given to oral health in national health policy and strategic plans, and lack of interest among public health administrators. A workshop on the effective use of fluoride in Asia took place in Phang-Nga, Thailand, in 2011. A series of country presentations addressed some of the topics mentioned above; in addition, speakers from countries of the region provided examples of successful fluoride interventions and discussed program limitations, barriers encountered, and solutions, as well as possibilities for expanding coverage. Participants acknowledged that automatic fluoridation through water, salt, and milk is the most effective and equitable strategy for the prevention of dental caries. Concerns were expressed that government-subsidized community fluoride prevention programs may face privatization. In addition, the use of affordable fluoride-containing toothpastes should be encouraged. The workshop identified: strengths and weaknesses of ongoing community-based fluoride programs, as well as the interest of countries in a particular method; the requirement for World Health Organization (WHO) technical assistance on various aspects, including fluoridation process, feasibility studies, and implementation of effective epidemiological surveillance of the program; exchange of information; and the need for inter-country collaboration. It was acknowledged that program process and evaluation at the local and country levels need further dissemination. The meeting was co-sponsored by the World Health Organization, the International Association for Dental Research, and the World Dental Federation.

The WHO Commission on Social Determinants of Health issued the 2008 report 'Closing the gap within a generation - health equity through action on the social determinants of health' in response to the widening gaps, within and between countries, in income levels, opportunities, life expectancy, health status, and access to health care. Most individuals and societies, irrespective of their philosophical and ideological stance, have limits as to how much unfairness is acceptable. In 2010, WHO published another important report on 'Equity, Social Determinants and Public Health Programmes', with the aim of translating knowledge into concrete, workable actions. Poor oral health was flagged as a severe public health problem. Oral disease and illness remain global problems and widening inequities in oral health status exist among different social groupings between and within countries. The good news is that means are available for breaking poverty and reduce if not eliminate social inequalities in oral health. Whether public health actions are initiated simply depends on the political will. The Ottawa Charter for Health Promotion (1986) and subsequent charters have emphasized the importance of policy for health, healthy environments, healthy lifestyles, and the need for orientation of health services towards health promotion and disease prevention. This report advocates that oral health for all can be promoted effectively by applying this philosophy and some major public health actions are outlined.

This paper reviews the shortcomings of present approaches to reduce oral diseases and inequalities, details the importance of social determinants, and links that to research needs and policies on implementation of strategies to reduce oral health inequalities. Inequalities in health are not narrowing. Attention is therefore being directed at determinants of major health conditions and the extent to which those common determinants vary within, between, and among groups, because if inequalities in health vary across groups, then so must underlying causes. Tackling inequalities in health requires strategies tailored to determinants and needs of each group along the social gradient. Approaches focusing mainly on downstream lifestyle and behavioral factors have limited success in reducing health inequalities. They fail to address social determinants, for changing people’s behaviors requires changing their environment. There is a dearth of oral health research on social determinants that cause health-compromising behaviors and on risk factors common to some chronic diseases. The gap between what is known and implemented by other health disciplines and the dental fraternity needs addressing. To re-orient oral health research, practice, and policy toward a ‘social determinants’ model, a closer collaboration between and integration of dental and general health research is needed. Here, we suggest a research agenda that should lead to reductions in global inequalities in oral health.

Background of the congress:The International Association for Dental Research (IADR) hosted the 9 th World Congress on Preventive Dentistry (WCPD) in Phuket, Thailand in September, 2009. Previous WCPD’s have been held approximately once every four years and are held in different parts of the world to communicate the latest research findings that can have a positive impact on dental public health and to fulfill part of IADR’s Mission, "to facilitate the communication and application of research findings."The theme for the 9 th WCPD was "Community Participation and Global Alliances for Lifelong Oral Health for All." The IADR partnered with many organizations from the public health, practice, research, and education communities—both globally and locally—to maximize the impact of the meeting.Objectives:Given the growing body of scientific evidence linking oral health to general health and the quality of life, the WCPD sought to: * build coalitions to implement the WHO Resolution (2007), Oral health: action plan for promotion and integrated disease prevention;* continue the work of the 8 th WCPD’s Liverpool Declaration and build on the science base for evidence-based approaches to promoting oral health at the community, national, regional, and global levels;*encourage the integration of oral health promotion and oral disease prevention policies into wider health promotion activities, including, but not limited to, a common risk factor approach; *provide networking opportunities for the scientific interchange of best practices for oral health promotion;*provide a platform for preventive dentistry research and successful implementation of evidence-based oral health promotion policies, especially from developing countries; and*improve the quality of life of people worldwide through optimal oral health.

Despite great improvements in oral health in the past decades, oral disease remains a major public health problem worldwide. The burden of oral disease is particularly high among the disadvantaged population groups in both developing and developed countries. The pattern of oral disease reflects distinct risk profiles across countries that are related to living conditions, lifestyles, environmental factors, and the availability and accessibility of oral health services. In several developing countries, people at large do not benefit from preventive oral health programmes. It is expected that the incidence of dental caries will increase in the near future in many of these countries as a result of growing consumption of sugars and inadequate exposure to fluorides. With the rising use of tobacco in developing countries, the risk of periodontal disease, tooth loss and oral cancer may therefore increase. Several oral diseases are linked to non-communicable chronic diseases or conditions that share common risk factors, such as diabetes, obesity and cancer. Similarly, general diseases often have oral manifestations (e.g. diabetes or HIV/AIDS).

Cancer is one of the most common causes of morbidity and mortality today. It is estimated that around 43% of cancer deaths are due to tobacco use, unhealthy diets, alcohol consumption, inactive lifestyles and infection. Low-income and disadvantaged groups are generally more exposed to avoidable risk factors such as environmental carcinogens, alcohol, infectious agents, and tobacco use. These groups also have less access to the health services and health education that would empower them to make decisions to protect and improve their own health. Oro-pharyngeal cancer is significant component of the global burden of cancer. Tobacco and alcohol are regarded as the major risk factors for oral cancer. The population-attributable risks of smoking and alcohol consumption have been estimated to 80% for males, 61% for females, and 74% overall. The evidence that smokeless tobacco causes oral cancer was confirmed recently by the International Agency for Research on Cancer. Studies have shown that heavy intake of alcoholic beverages is associated with nutrient deficiency, which appears to contribute independently to oral carcinogenesis. Oral cancer is preventable through risk factors intervention. Prevention of HIV infection will also reduce the incidence of HIV/AIDS-related cancers such as Kaposi sarcoma and lymphoma. The WHO Global Oral Health Programme is committed to work for country capacity building in oral cancer prevention, inter-country exchange of information and experiences from integrated approaches in prevention and health promotion, and the development of global surveillance systems for oral cancer and risk factors. The WHO Global Oral Health Programme has established a global surveillance system of oral cavity cancer in order to assess risk factors and to help the planning of effective national intervention programmes. Epidemiological data on oral cancer (ICD-10: C00-C08) incidence and mortality are stored in the Global Oral Health Data Bank. In 2007, the World Health Assembly (WHA) passed a resolution on oral health for the first time in 25 years, which also considers oral cancer prevention. The resolution WHA60 A16 URGES Member states--To take steps to ensure that prevention of oral cancer is an integral part of national cancer-control programmes, and to involve oral-health professionals or primary health care personnel with relevant training in oral health in detection, early diagnosis and treatment;--The WHO Global Oral Health Programme will use this statement as the lead for its work for oral cancer control www.who.int/oral_health.

The purpose of this report is to review the interrelationship between poor oral health conditions of older people and general health. The impact of poor oral health on quality of life (QOL) is analyzed, and the implications for public health intervention and oral health care are discussed. Findings from the current research may lead to the following conclusions: The available scientific evidence is particularly strong for a direct relationship between diabetes and periodontal disease; the direct relationship between periodontal disease and cardiovascular disease is less convincing. General and associated oral health conditions have a direct influence on elder people's QOL and lifestyle. The growing number of elderly people challenges health authorities in most countries. The evidence on oral health-general health relationships is particularly important to WHO in its effort to strengthen integrated oral health promotion and disease prevention around the globe.

The World Health Organization (WHO) Global Oral Health Programme has worked hard over the past five years to increase the awareness of oral health worldwide as an important component of general health and quality of life. Meanwhile, oral disease is still a major public health problem in high income countries and the burden of oral disease is growing in many low- and middle income countries. In the World Oral Health Report 2003, the WHO Global Oral Health Programme formulated the policies and the necessary actions for the improvement of oral health. The strategy is that oral disease prevention and the promotion of oral health needs to be integrated with chronic disease prevention and general health promotion as the risks to health are linked. The World Health Assembly (WHA) and the Executive Board (EB) are supreme governance bodies of WHO and for the first time in 25 years oral health was subject to discussion by those bodies in 2007. At the EB120 and WHA60, the Member States agreed on an action plan for oral health and integrated disease prevention, thereby confirming the approach of the Oral Health Programme. The policy forms the basis for future development or adjustment of oral health programmes at national level.

Objectives: The purpose of this study was to analyze the life-course effects of education, occupation, and income at ages 70, 75, 80, and 85 years, respectively, on dental caries experience of 85-year-olds. Methods: The present study includes follow-up data from a population-based study, which comprised a sample of 176 individuals aged 85 years. Data on social position were collected at ages 70, 75, 80, and 85 years by means of structured personal interviews. Clinical oral health examinations were conducted to obtain data on dental caries at age 85. Dental caries was recorded at tooth surface level and caries experience was expressed by the DMF Index: the decayed tooth surfaces (D component), missing tooth surfaces (M component), and filled tooth surfaces (F component). Results: The participants in the present study demonstrated a high level of dental caries experience; the prevalence rate for active dental caries (D-S) was 80 percent. Older adults with low education, low occupational status, and poor income tended to have more active dental caries compared to their counterparts. In contrast, individuals with high education (F-S = 35.5) and high occupational status (F-S = 36.0) had significantly more filled surfaces than persons with low education (F-S = 24.0) and low occupational status (F-S = 25.6). Individuals with high income at ages 75, 80, and 85 years had more filled surfaces (F-S = 31.9, 33.2, 34.1) compared to persons with low income (F-S = 25.5, 23.5, 22.8). Conclusion: The study identified social inequalities across age among the very old individuals in relation to dental caries experience.

The purpose of the present study was to measure the consumption of dental services among adults in Denmark and to analyze at what level socio-demographic/socio-economic factors influence dental attendance and oral examinations. A sample of 10% of the total population of 18 yr or older was randomly drawn from a population register, based on a cross-sectional design. Information on the use of dental services was retrieved from public registers along with data on gender, age-group, regions, ethnicity, education, marital status, and income. In addition, a cohort of persons was drawn from the sample in 1999 including only persons who were registered as residents in Denmark from 1999 to 2003. Over time, an increase in the number of dental visits and oral examinations was found among persons older than 45 yr, whereas a decrease was observed in the younger age-groups. Logistic regression analysis was applied to determine the effect of various variables on the experience of dental visits and oral examinations, and relatively high odds for dental attendance and oral examinations was found for the following: younger adults; women; married persons; high income; high education; and persons of Danish origin. The present dental healthcare system does not yet seem to have established mechanisms to address social inequalities in the consumption of dental services.

Objective: To assess the oral hygiene practices, current use of and knowledge about fluoride toothpaste among schoolchildren, parents, and schoolteachers; to describe the attitudes of parents and schoolteachers in relation to improving schoolchildren’s oral health. Design: Cross-sectional study. Participants: 1,557 schoolchildren, 1,132 parents, and 352 schoolteachers were recruited by multistage stratified sampling procedure in a district of Beijing, China. Methods: Self-completed questionnaire. Results: The percentage of schoolchildren, parents, and schoolteachers who actually used fluoride toothpaste was 88%, 86%, and 87%, respectively, and 74-78% of the respondent groups brushed their teeth twice a day or more. 64% of schoolchildren, 73% of parents, and 74% of schoolteachers confirmed the caries preventive effect of fluoride toothpaste. Toothpaste recommended by oral health professional organisations was preferred by respondents - particularly by schoolchildren - when purchasing toothpaste (86%). 93% of parents and 56% of schoolteachers recognised their important role in promoting children’s oral health; however, their lack of knowledge seemed to be a major obstacle in fulfilling this role. Conclusions: The use of fluoride toothpaste in Beijing appears to have increased during the past decade. In addition to mass communication comprehensive school-based oral health programmes are needed to continuously promote the use of fluoride toothpaste among schoolchildren.

Chronic diseases and injuries are overtaking communicable diseases as the leading health problems in all but a few parts of the world. This rapidly changing global disease pattern is closely linked to changing lifestyles which include diet rich in sugars, widespread use of tobacco and increased consumption of alcohol. These lifestyle factors also significantly impact oral health, and oral diseases qualify as major public health problems owing to their high prevalence and incidence in all regions of the world. Like all diseases, they affect primarily the disadvantaged and socially marginalized populations, causing severe pain and suffering, impairing functionability and impacting quality of life. Traditional treatment of oral diseases is extremely costly even in industrialized countries and is unaffordable in most low and middle-income countries. The WHO Global Strategy for prevention and control of noncommunicable diseases and the ”common risk factor approach” offer new ways of managing the prevention and control of oral diseases. This report outlines major characteristics of the current oral health situation in Africa and development trends as well as WHO strategies and approaches for better oral health in the 21st century. Key Words: Africa; oral health; risk factor; development African Journal of Oral Health Vol.1(1) 2004: 2-16

To assess the level of dental knowledge and attitudes among 12 year-old children and 35-44 year-olds in Burkina Faso; to evaluate the pattern of oral health behaviour among these cohorts in relation to location, gender and social characteristics and; to evaluate the relative effect of social-behavioural risk factors on caries experience.Across sectional study including urban and rural subgroups of population.Multistage cluster sampling of households in urban areas; in rural areas random samples of participants were based on the recent population census. The final study population covered two age groups: 12 years (n = 505) and 35-44 years (n = 493).For both children and adults, levels of oral health knowledge, attitudes and self-care were low; 36% of 12-year-olds and 57% of 35-44-year-olds carried out toothcleaning on a daily basis. Pain and discomfort from teeth were common while dental visits were infrequent. Tooth cleaning was mostly performed by use of chewsticks. Use of toothpaste was rare, particularly fluoridated toothpaste was seldom; 9% of 12-year-olds and 18% of 35-44-year-olds reported use of fluoride toothpaste. Significant differences were found in oral health knowledge, attitudes and practices according to location and gender. At age 12, important factors of high caries experience were location (urban), and consumption of soft drinks and fresh fruits. In 35-44-year-olds, gender (female), high education level, dental visit and occupation (government employee) were the significant factors of high dental caries experience whereas adults using traditional chewing sticks had lower DMFT.Health authorities should strengthen the implementation of oral disease prevention and health promotion programmes rather than traditional curative care. Community-oriented essential care and affordable fluoride toothpaste should be encouraged.
