Utilization of a public subsidy scheme for dental care services among socially vulnerable citizens out of labor in Copenhagen, Denmark

Objective Addressing social inequality in oral health and access to dental care is a global concern. This study aims to describe the utilization of a public subsidy scheme targeting vulnerable individuals out of labor in Copenhagen municipality (2013–2018) and to identify key characteristics of individuals eligible to apply. Material and Methods Data from Copenhagen municipality were combined with data from population and health registers. Employing logistic regression analyses, we examined the association between demographic, socioeconomic, and health-related characteristics and (1) having applied, (2) being granted, and (3) using the subsidy. Results The study included 65,174 individuals aged 18–65. Of these 10,369 (15.9%) applied for subsidies, submitting a total of 18,529 applications. Overall, 83% of the applications were granted and 85% were used. Significantly increased odds of applying for subsidies were observed among individuals receiving social benefits non-stop over the past year versus none (odds ratio [OR] = 15.45, 95% confidence interval [CI] = 14.24–16.76), aged 50–65 versus 18–29 years (OR = 4.41, CI = 4.15–4.69), and having combined indicators of social vulnerability versus none (OR = 2.90, CI = 2.73–3.07). Conclusions While the utilization of the public subsidy scheme is low, individuals who apply are likely to be granted a subsidy and use it. Vulnerability was associated with greater utilization of the scheme, yet a substantial portion of those at risk of poor oral health did not take advantage of it.

The intersections of socioeconomic position, gender, race/ethnicity and nationality in relation to oral conditions among American adults.

The objective of the study was to evaluate how gender, socioeconomic position (SEP), race/ethnicity and nationality intersect to structure social inequalities in adult oral health among American adults. Data from adults aged 20 years or over who participated in the National Health and Nutrition Examination Survey (NHANES) 2009-2018 were analysed. The outcomes were poor self-rated oral health and edentulism among all adults (n= 24 541 and 21 446 participants, respectively) and untreated caries and periodontitis among dentate adults (n= 16 483 and 9829 participants, respectively). A multilevel analysis of individual heterogeneity and discriminatory accuracy (MAIHDA) was conducted for each outcome, by nesting individuals within 48 intersectional strata defined as combinations of gender, SEP, race/ethnicity and nationality. Intersectional measures included the variance partition coefficient (VPC), the proportional change in variance (PCV) and predicted excess probability due to interaction. Substantial social inequalities in the prevalence of oral conditions among adults were found, which were characterized by high between-stratum heterogeneity and outcome specificity. The VPCs of the simple intersectional model showed that 9.4%-12.7% of the total variance in the presentation of oral conditions was attributed to between-stratum differences. In addition, the PCVs from the simple intersectional model to the intersectional interaction model showed that 84.1%-97.1% of the stratum-level variance in the presentation of oral conditions was attributed to the additive effects of gender, SEP, race/ethnicity and nationality. The point estimates of the predictions for some intersectional strata were suggestive of an intersectional interaction effect. However, the 95% credible intervals were very wide and the estimations inconclusive. This analysis highlights the value of the intersectionality framework to understand heterogeneity in social inequalities in oral health. These inequalities were mainly due to the additive effect of the social identities defining the intersectional strata, with no evidence of interaction effects.

Determinants of maternal and household social inequalities of dental caries among Senegalese children in the Department of Pikine.

the problematic of social Inequalities in oral health remains a global concern; it constitutes evidence of social injustice. The present work aims to study the determinants of maternal and household social inequalities of children´s dental caries in Pikine. cross-sectional epidemiological survey has been conducted in the department of Pikine, Senegal on 315 children aged 3 to 9 and their mothers. The clinical data on children´s caries have been obtained by clinical examination and the socio-economic data by a questionnaire submitted to mothers. Pearson chi-square and trend tests as well as a logistic model were used in the data analysis. the prevalence of dental caries in children was 64.8% and the mixed decayed, filled, missing (DFM) index was 2.5 (±2.7). The trend test showed significant inequalities in the prevalence of dental caries according to level of studies (p<0.001), profession (p<0.010) and contacts frequency (p<0.001) of mothers; the level of wealth (p<0.001) and structure (p<0.005) of households. According to the logistic regression model, the level of secondary or university education [OR (IC 95%) = 0.59 (0.33'>OR (IC 95%) = 0.59 (0.33-0.93)] or social network dynamism [OR (IC 95%) = 0.32(0.15'>OR (IC 95%) = 0.32(0.15-0.67)] of mothers; as well as wealthy families [OR (IC 95%) = 0.23(0.08'>OR (IC 95%) = 0.23(0.08-0.64) were associated to fewer risks of dental caries among children. some socio-economic characteristics of the mother and the household social conditions are identified as determinants of dental caries social inequalities in Children. Proportionate universalism may be a good approach to reduce this problematic in Pikine.

Therapeutic education and oral health, an opportunity for the child

Early childhood caries is an infectious disease of bacterial origin. It is mainly associated with social inequalities in oral health and affects children from the least privileged backgrounds. Because of its recurrent nature, it is the most common chronic disease in preschool children. Since it shares common risk factors with a number of other chronic conditions (diabetes, obesity), promoting global oral health is essential to achieving a favorable general health status.

Changes in oral health inequalities in adults in Chile.

A secondary analysis of data from 2003 and 2016-2017National Health Surveys (NHS) in Chile was performed on seven oral health outcomes in adults: prevalence of untreated caries, prevalence of severe untreated caries, number of teeth with untreated caries, prevalence of functional dentition, prevalence of edentulism, number of remaining natural teeth and utilization of dental services. Inequalities were measured with the Slope Index of Inequality (SII) and the Relative Index of Inequality (RII) by education level. A decrease of caries inequalities measured with SII was observed from 2003 to 2016-17NHS but an increase of remaining teeth inequalities was measured. The SII of the remaining teeth increased from 6.6 [95% CI=5.0, 8.2] in 2003 to 8.8 [95% CI=7.3, 10.3] in 2016-17. The SII of functional dentition by education increased from 29.0 [95% CI=22.0, 36.0] in 2003 to 38.8 [95% CI=32.6, 45.0]) in 2016-17. The utilization of dental services ≤1year was the only outcome that showed a decrease in absolute and relative inequality, the SII was 33.9 [95% CI=23.3, 45.6] in 2003 and 26.2 [95% CI=16.6, 35.8] in 2016-17 and the RII decreased from 2.5 [95% CI=1.7, 3.3] in 2003 to RII=1.8 [95% CI=1.4, 2.3] in 2016-17. The increase of tooth loss inequalities in contrast to the decrease of inequalities in dental services utilization show the need to re-evaluate the current dental programmes for adults in Chile. This may include establishing a stronger oral health promotion strategy and greater dental treatment coverage focusing on avoiding tooth extractions in vulnerable social groups.

Inégalités sociales de santé orale et caries précoces de l’enfant : comment prévenir efficacement ? Une revue de portée des prédicteurs de la maladie

BackgroundEarly childhood caries represent a major public health problem. In addition to their individual impact, the massive social inequalities in oral health that are at the roots and result from the disease have largely underestimated consequences for the child, his family and the community. In response to the question of “how and where to act?”, this scoping review identifies the individual characteristics associated with the disease on which it would be possible to act, using appropriate prevention strategies. MethodsThis scoping review is aimed at describing and analyzing available data in the literature on the different factors associated with early childhood caries. ResultsThe predictors of early childhood caries are represented by mediating (knowledge, attitudes and parents’ oral health practices) and moderating (psychosocial parameters, parental health literacy and alcohol consumption) factors. Twenty-eight articles fulfilled the selection criteria, twenty of which studied mediators related to early childhood caries, and fourteen of which dealt with moderators. The lower the parents’ level of knowledge and literacy in oral health, the higher a child's dmft index. Additional studies are needed to assess the role of psychosocial parameters. ConclusionParents’ knowledge and oral health literacy are the key predictors to be preferentially targeted in view of reducing social inequalities in health through actions undertaken on a local scale. The prevention of early childhood caries necessitates a combination of generic and targeted interventions.

Mothers’ Oral Health Literacy and children’s oral health: study in the department of Pikine, Senegal

Abstract Background Several studies have shown that social conditions in which children are raised and family psychosocial factors affect their oral health. Oral health literacy (OHL) has been shown to be associated with prevalence of dental caries, access to care and prevention of oral diseases. No studies have addressed this issue in Senegal. Objective: To study the characteristics of the mothers’ OHL and its association with children’s dental health. Methods Cross- sectional study in the district of Pikine, a suburb of Dakar including 16 municipalities. Two-stage cluster sampling and a sample comprising 315 children from 3 to 9 years old and their mothers. Data on oral health status were collected from clinical examinations, sociodemographic and OHL (Sistani et al’ OHL-AQ) data were collected during face-to-face interview. Results More than half of the mothers (56.5%) had a low OHL, but 68.9% had an adequate score for the communication/interactive dimension. The level of OHL increased significantly with education level, household wealth and dynamism of the social support. Prevalence of dental caries was 64.8%, following a social gradient and significantly associated with the mothers’ OHL level (OR = 5.2) CI[2.2-14.1]. The oral health behaviour of families was significantly associated with the level of OHL and children’s dental health. A structural equation model showed the OHL was a mediating factor between social characteristics and oral health behaviours. Conclusions The OHL of mothers is an important variable to be included in the study of social inequalities in oral health. The communication/interactive dimension seems to be decisive in the African context of an oral culture and dynamic social support which makes it possible to provide better knowledge and preventive behaviour. Key messages High maternal OHL should be reinforced to lessen oral health inequalities among Senegalese children. The communication/interactive dimension seems to be decisive in the African context of an oral culture and dynamic social to enhance OHL.

Family Affluence Based Inequality in Oral Health-Related Quality of Life in a Population of Lithuanian Adolescents.

Background: The social inequalities in oral health have had increasing attention in recent years. The present study aimed to explore the impact of family affluence on Oral Health-Related Quality of Life (OHRQoL) among Lithuanian adolescents aged 11–18 years. Methods: The cross-sectional, population-based study included a representative sample of 881 adolescents aged 11–18 years (mean = 15.55; SD = 1.51) randomly selected from 20 schools in Lithuania. The schoolchildren completed questionnaires to evaluate their OHRQoL using a Lithuanian version of the Child Perceptions Questionnaire (CPQ). The adolescents’ family affluence was indirectly assessed by inquiring whether they possessed various modern life items. In dental examination, the severity of malocclusion was predetermined by the Index of Complexity, Outcome, and Need (ICON). The relationship among variables was examined employing the negative binomial regression and the path analysis. Results: The sum score of CPQ as a whole and the sum scores of all four domains were significantly associated with family affluence, indicating higher OHRQoL among adolescents from more affluent families. The severity of malocclusion had a significant association with emotional and social well-being domains of OHRQoL only. Conclusion: This study evidences the family affluence based inequality in OHRQoL among Lithuanian adolescents.

School Dental Service in Sri Lanka: geo-spatial analysis of access to oral health care.

The School Dental Service contributes to the reduction of social inequalities in oral health among school children. To investigate the distribution of School Dental Clinics staffed by School Dental Therapists in Sri Lanka in relation to the distribution of the child population and socioeconomic status. School Dental Clinics were mapped using geographic information system (GIS) software and overlayed with population data of 3-13-year-old children (including poverty status). Overall, there was an uneven geographic distribution of the total 422 School Dental Clinics. Sri Lankan children have restricted access to school dental care in a few poverty stricken districts in the Northern, Eastern, North Central, and Uva provinces. When the geographic distribution of children by poverty status was analysed, it was found that in Sri Lanka, only 53% of the most socially disadvantaged children lived within 5 km from a School Dental Clinic, compared to 75% of the least disadvantaged. A coordinated national School Dental Service strategy is needed in response to identified areas of poor or inadequate accessibility to dental services for large parts of the child population, especially those from low socioeconomic backgrounds.

Social inequalities in oral health in a group of older people in a Middle Eastern country: a cross-sectional survey.

The percentage of Lebanese older people has increased considerably. Given that Lebanese seniors are marginalized in the health policy-making process, we suggest a high social inequality in oral health that has not been studied so far. The purpose of our study was to describe and compare oral health status in a group of Lebanese older people according to their socioeconomic status (SES) MATERIALS AND METHODS: Participants were recruited from three different primary health care clinics in Beirut, Lebanon. Data were collected from an administered questionnaire that included sociodemographic variables, perception of oral health, and regular dental visits. Oral examination included the number of missing and decayed teeth, the prosthetic status, and the number of functional dental units (FUs). The SES of the participants was determined by educational level, previous or actual work, and neighborhood level. 264 participants aged 71.4 ± 6.27years (64.7% female) were included in the study. Regular dental visit, dental status, FU, and oral health perception were significantly related to the participants' place of residence, educational level, and work. Moreover, the mean number of missing teeth (p = 0.048) and decayed teeth (p = 0.018) was significantly elevated in the low SES. There is a clear socioeconomic inequality in oral health among the Lebanese older people. Further researches should explore the potential contribution of psychosocial and behavioral factors in explaining these disparities.

An illustrated guide to dental screening: a school survey

Marked social inequalities in oral health are observed right from early childhood. A mandatory complete health check-up, including dental screening, is organized at school for 6-year-old children. School healthcare professionals are not well trained in dental health. The aim of this study was to assess the relevance of an illustrated guide as a simple and rapid dental screening training tool in order to ensure effective, standardized and reproducible screening. A cross-sectional study was conducted in the context of the dental examination performed as part of the health check-up. Two examiners (Doctor E1 and Nurse E2) were trained in dental screening by means of the illustrated guide. This reference guide, comprising pictures and legends, presents the main oral pathology observed in children. 109 consent forms for oral screening were delivered, and 102 children agreed to participate (93.57%). The sensitivity of detection of tooth decay by examiners E1 and E2 was 81.48% with a specificity of 96%. No correlation was observed between the child's age (+/- 6 years) and correct detection rates. The illustrated guide is an appropriate and rapid tool for dental screening that can improve the quality of dental check-up and increase the number of children detected.

Social inequalities in adult oral health in 40 low- and middle-income countries

This study evaluated social inequalities in adult oral health across several low- and middle-income countries. We used data from 40 countries that participated in the World Health Surveys. Participants' socio-economic position was assessed using the wealth index. Oral health was assessed using two perceived measures, namely total tooth loss and whether they had any problems with their mouth and/or teeth during the last 12 months (perceived needs). Absolute and relative wealth inequalities in oral health were measured using the slope index of inequality (SII) and the relative index of inequality (RII), respectively, after adjusting for participants' sex, age and education. There were wealth inequalities in total tooth loss and perceived needs in most countries. However, significant monotonic gradients were found in 21 countries for total tooth loss and in 18 countries for perceived needs. Two distinctive patterns of social inequality in oral health were found across countries using the RII and the SII. For total tooth loss, pro-rich inequality was found in 25 countries (significant RII/SII in eight countries) and pro-poor inequality was found in 15 (significant RII/SII in three countries). For perceived needs, pro-poor inequality was found in 26 countries (significant RII/SII in six countries) and pro-rich inequality was found in 14 (significant RII/SII in five countries). The well-documented social gradient in adult oral health favouring the rich was not present in all low- and middle-income countries. Pro-poor inequalities in total tooth loss, and particularly in perceived dental-treatment needs, were observed in some countries.

Inequality in oral health related to early and later life social conditions: a study of elderly in Norway and Sweden.

BackgroundA life course perspective recognizes influences of socially patterned exposures on oral health across the life span. This study assessed the influence of early and later life social conditions on tooth loss and oral impacts on daily performances (OIDP) of people aged 65 and 70 years. Whether social inequalities in oral health changed after the usual age of retirement was also examined. In accordance with “the latent effect life course model”, it was hypothesized that adverse early-life social conditions increase the risk of subsequent tooth loss and impaired OIDP, independent of later-life social conditions.MethodsData were obtained from two cohorts studies conducted in Sweden and Norway. The 2007 and 2012 waves of the surveys were used for the present study. Early-life social conditions were measured in terms of gender, education and country of birth, and later-life social conditions were assessed by working status, marital status and size of social network. Logistic regression and Generalized Estimating Equations (GEE) were used to analyse the data. Inverse probability weighting (IPW) was used to adjust estimates for missing responses and loss to follow-up.ResultsEarly-life social conditions contributed to tooth loss and OIDP in each survey year and both countries independent of later-life social conditions. Lower education correlated positively with tooth loss, but did not influence OIDP. Foreign country of birth correlated positively with oral impacts in Sweden only. Later-life social conditions were the strongest predictors of tooth loss and OIDP across survey years and countries. GEE revealed significant interactions between social network and survey year, and between marital status and survey year on tooth loss.ConclusionThe results confirmed the latent effect life course model in that early and later life social conditions had independent effects on tooth loss and OIDP among the elderly in Norway and Sweden. Between age 65 and 70, inequalities in tooth loss related to marital status declined, and inequalities related to social network increased.

Translating knowledge on poverty to humanize care: benefits and synergies of community engagement with the arts

The knowledge translation movement in health has led to the production of vast amounts of knowledge tools aimed at broadening clinicians’ evidence base and improving the quality and efficacy of their practices. However important, these tools, largely oriented towards biomedical and technological aspects of care, are of limited potential for addressing the complex interactions between patients’ socio-economic contexts and their health. Yet health professionals frequently lack the sensitivity, knowledge and ability to incorporate approaches to poverty within their practices; this is partly due to their limited understanding of the lived experience of poverty and of the complexity of barriers underprivileged people face to achieve and maintain health. In a context of persisting social inequalities in oral health, the Montreal-based Listening to Others multi-stakeholder partnership has been engaged in developing health professional education on poverty since 2006. In this article, we describe and reflect on how service users representing the Québec antipoverty coalition, academics from University of Montreal and McGill University, representatives of Québec dental regulatory bodies and artists collaborated to produce an educational film on poverty. Project partners’ specific contributions to the film script are highlighted, emphasizing their potential to enrich the health professional educator’s practice knowledge base. In doing so, this article provides an explicit and concrete example of how participatory processes can support co-learning and knowledge co-production through engagement with the arts. The overall aim is to demonstrate how participatory research can enhance knowledge translation by producing educational tools that promote critical reflection and address complexity.

Socioeconomic differences in self-rated oral health and dental care utilisation after the dental care reform in 2008 in Sweden.

BackgroundThe aims of this study were to determine self-rated oral health and dental attendance habits among Swedish adults, with special reference to the role of social inequalities, after the Swedish dental care reform in 2008.MethodsThe study is based on a survey questionnaire, sent to 12,235 residents of a Swedish county, in 2012. The age group was 16–84 years: 5,999 (49%) responded. Using chi-square statistics, differences in prevalence of self-rated oral health and regular dental attendance were analysed with respect to gender, age, educational level, family status, employment status and country of birth. Self-rated poor oral health was analysed by multivarite logistic regression adjusting for the different socio-demographic factors, financial security and having refrained from dental treatment for financial reasons.ResultsThree out of four respondents (75%) reported fairly good or very good oral health. Almost 90% claimed to be regular dental attenders. Those who were financially secure reported better oral health. The differences in oral health between those with a cash margin and those without were large whereas the differences between age groups were rather small. About 8% reported that they had refrained from dental treatment for financial reasons during the last three months. Self-rated poor oral health was most common among the unemployed, those on disability pension or on long-term sick leave, those born outside the Nordic countries and those with no cash margin (odds ratios ranging from 2.4 to 4.4). The most important factor contributing to these differences was having refrained from dental treatment for financial reasons.ConclusionThe results are relevant to strategies intended to reduce social inequalities in oral health, affirming the importance of the provision of equitable access to dental care.

Epidemiology and prevention of dental caries

Dental caries is a chronic disease with low mortality. It is, though, a very common disease, responsible for much suffering, and is one of the most expensive diseases to treat. Within the EU, the cost of dental treatment, most related to dental caries, in 2011 was estimated to be 79 billion euro (1). Dental caries affects all ages; both primary and permanent dentitions. In many European countries, tooth extraction due to dental caries is the commonest reason for general anaesthetics in young children. Yet, it is a preventable disease; its cause is very well known but it is not prevented. Why? Because it is a diet-related lifestyle disease, where prevention requires change to entrenched, and often enjoyable, eating habits. Dental caries was rare before the rise in importation and consumption of sugar. Sugar causes much pleasure but also much disease – and not only dental caries. Strong commercial pressures encourage sugar consumption. However, there are signs that the tide is changing. Medical, dietetic and dental professions now agree on dietary policy. There is much better food labelling now in Europe, with sugars content displayed. In many countries, television advertising of high sugar products cannot be targeted at children, and provision of high sugar foods and drinks is not allowed in schools. Many parents are now well aware of what a healthy diet is and do their best to ensure their children benefit from this knowledge. However, there are many families where life’s pressures – financial, availability of time and food choice, and habit – are such that this is not possible. These differences have led to increased social inequality in oral health: the major challenge to those in population oral health. Ironically, it used to be the affluent who had most dental decay; now it is the opposite. This scenario is common to several chronic diseases, often with the same risk factors operating in these several diseases. This requires, what is now well-recognised as the ‘common risk

Inequalities of dental prosthesis use under universal healthcare insurance

Social inequalities in oral health exist in various countries. In Japan, a country with universal healthcare insurance policy, people can receive medical and dental care and pay only 10-30% of the total cost of treatment. Additionally, very poor Japanese can receive care without any charge, by the benefit of public assistance. These policies are considered to affect oral health inequalities. This study examined the association between using a dental prosthesis and household income among older Japanese people. Self-administered questionnaires were mailed to subjects as part of the Japan Gerontological Evaluation Study (JAGES) project in 2010. Of the 8576 people aged 65years or more living in Iwanuma, Japan, 5058 responded. We used 4001 respondents with no missing values. We stratified into two groups by having 20 teeth or not. Then, cross-tabulation, univariate logistic regression, and multivariate logistic regression were conducted for these two groups. The covariates are sex, age, education, and size of household. Of the all respondents included in the analyses, poorer respondents tended to have lower proportions with 20 or more teeth, and 54.6% respondents used dental prostheses. In the respondents with 19 or fewer teeth, higher-income group tended to show significantly higher dental prosthesis use. But the poorest income group showed high prevalence of dental prosthesis use as same as highest income group. Multiple logistic regression among respondents with 19 or fewer teeth showed that after adjustment for sex, age, education, and size of household, compared with the respondents with annual incomes of US$ <5000, those with incomes of US$5000-9999 and US$10000-14999 had significantly lower odds ratios for using a dental prosthesis (OR=0.48 [95% CI=0.28-0.83], 0.56 [95% CI=0.33-0.95], respectively). The other respondents did not show significant differences. Although universal healthcare insurance covered dental prostheses, a social gradient in dental prosthesis use was still observed. Low-income respondents tended to not use dental prosthesis, but the poorest respondents showed dental prosthesis utilization as high as the highest income group.

Social inequality in oral health

Social inequalities in oral health are observable regardless of the population, the culture, the method of social classification or the measure of oral health or disease. They exist because of socially determined differences in opportunity, behaviours, beliefs and exposure to the myriad factors which determine our oral health. Behaviours and practices which affect oral health are embedded in the normal patterns of everyday life; those (in turn) are socially determined and differ across the continuum of social status. This presentation focuses primarily on social inequalities in incremental tooth loss because (i) it is a condition which has been shown to have the greatest effect on people's oral-health-related quality of life, and (ii) it is cumulative and irreversible. Most of the knowledge base on social inequalities in tooth loss comes from cross-sectional studies; investigating the phenomenon in a birth cohort can be more informative because it allows us to determine what happens to those inequalities through the life course. Data on incremental tooth loss from a longstanding cohort study (the Dunedin Multidisciplinary Health and Development Study) are presented to illustrate the cumulative and pervasive effect of social inequalities and changes in social status between childhood and adulthood.

Sociodemographic factors associated with the dental health of persons with diabetes in France

This paper describes and compares the oral health status among people with and without diabetes in France, and analyzes the related socioeconomic factors. The study is based on data from the cross-sectional national health survey conducted in France from 2002 to 2003, which included 19,231 people over 35 years of age, among whom 1,111 reported having diabetes. Data were collected through interviews that inquired about oral health status and use of dental care services, income, educational level, health insurance, place of residence, and birthplace. The prevalence of oral health problems was higher among subjects who had diabetes, compared with those who were nondiabetic (16.4% vs. 13.4%). Dental care utilization during the survey period was reported to be 8.7% among subjects who were diabetic versus 12.9% among those who were nondiabetic. The subjects with diabetes were more likely to have dental problems (OR = 1.47, CI = 1.03-2.08) and wear removable dentures (partial and complete) when their income was lower (OR = 2.17, CI = 1.52-3.10). There were social inequalities in oral health among people with diabetes in France according to income level.

An effective oral health promoting message?

This paper questions the effectiveness of current oral health promoting activities in reducing social inequalities in oral health. An attempt is made to address the needs of dental professionals and nutritionists in communicating an understanding of biological aspects of the aetiology of caries and erosion. With a clear understanding of the disease process oral health promoters can possibly reduce social inequalities in oral health. A clear common message which satisfies both dental and nutritional professionals is presented. The issues of commonality and ambiguity are fundamental to effective behavioural/teaching practice. Currently the evidence base suggests that dietary messages are inconsistent and ambiguous. Therefore, a clear common and unambiguous dietary message, based on science, could go some way to improving oral health inequalities.
