RESUMO
There are no high-quality data on dietary behaviour of adolescents in India. This study aimed to assess the intake of energy (E), macronutrients and selected micronutrients in a sample of 11-13-year-old schoolchildren in Delhi, India. Participants from private schools (n=10) recorded dietary intake using a 3-d food diary. Information was entered into the dietary assessment tool, Intake24, to ascertain portion size and convert data into nutrient intake through integrated food tables. Of the 514 consenting participants, 393 (76·4 %) (169 girls, 224 boys) aged 11·4 (±1·8) years completed the study. The median (interquartile range (IQR) daily E intake was 2580 (2139·3-2989·8) kcal (10·8 (9·0 - 12·5) MJ) for girls and 2941·5 (2466·7-3599·3) kcal (12·3 (10·3-15·2) MJ) for boys. The median (IQR) daily nutrient intakes for girls and boys respectively were protein 64·6 (54·8-79·3) g, 74·4 (61·4; 89·4) g; carbohydrate 336·5 (285·3-393·6) g, 379·6 (317·8-461·8) g; and saturated fat 45·6 (34·8-58·3) g, 54·6 (41·9-69·5) g. There were no significant between-gender differences in percentage E from protein (10·2 (9·2-11·4)), or carbohydrate (52·4 (48·7-56·7)). Girls obtained less percentage E from saturated fat (16·1 (11·0-18·2) compared with boys 16·3 (14·2-19·1) (P < 0·05). E from saturated fat was above FAO recommendations in >74 % of participants. The estimated average requirement for iron was achieved by < 40 % of girls. In conclusion, strategies to optimise the dietary intake of adolescents in India should focus on preventing excess intakes of E and saturated fat and improving iron intake in girls.
RESUMO
OBJECTIVES: To investigate the relationship between access to fluoridated drinking water and area-level socio-economic status in Queensland. STUDY DESIGN: Ecological, geospatial data linkage study. SETTING: Queensland, by statistical area level 2 (SA2), 2021. MAIN OUTCOME MEASURES: Proportion of SA2s and of residents with access to fluoridated drinking water (natural or supplemented); relationship at SA2 level between access to fluoridated water and socio-economic status (Index of Relative Socio-economic Advantage and Disadvantage, IRSAD; Index of Economic Resources, IER). RESULTS: In 2021, an estimated 4 050 168 people (79.4% of the population) and 397 SA2 regions (72.7%) in Queensland had access to fluoridated water. Access was concentrated in the southeastern corner of the state. After adjusting for SA2 population, log area, and population density, the likelihood of access to fluoridated drinking water almost doubled for each 100-rank increase in IRSAD (adjusted odds ratio [aOR], 1.93; 95% confidence interval [CI], 1.59-2.36) or IER (aOR, 1.77; 95% CI, 1.50-2.11). CONCLUSIONS: The 2012 decision to devolve responsibility for water fluoridation decisions and funding from the Queensland government to local councils means that residents in lower socio-economic areas are less likely to have access to fluoridated water than those in more advantaged areas, exacerbating their already greater risk of dental disease. Queensland water fluoridation policy should be revised so that all residents can benefit from this evidence-based public health intervention for reducing the prevalence of dental caries.

OBJECTIVE: To develop and internally validate a Free Sugars Screener (FSS) for Australian children aged 2 and 5 years. DESIGN: Using data collected from a ninety-nine-item (2-year-olds) and ninety-eight-item (5-year-olds) FFQ in the Study of Mothers' and Infants' Life Events affecting oral health (SMILE-FFQ), a regression-based prediction modelling approach was employed to identify a subset of items that accurately estimate total free sugars intake (FSI). The predictors were grams of free sugars (FSg) for individual items in the SMILE-FFQ and child's age and sex. The outcome variable was total FSI per person. To internally validate the SMILE-FSS items, the estimated FSg was converted to percent energy from free sugars (%EFS) for comparison to the WHO free sugars guideline categories (< 5 %, 5-< 10 % and ≥ 10 %EFS) using cross-classification analysis. SETTING: Australia. PARTICIPANTS: 858 and 652 2- and 5-year-old children, respectively, with complete dietary (< 5 % missing) and sociodemographic data. RESULTS: Twenty-two and twenty-six items were important in predicting FSI at 2 and 5 years, respectively. Items were similar between ages with more discretionary beverage items (e.g. sugar-sweetened beverages) at 5 years. %EFS was overestimated by 4·4 % and 2·6 %. Most children (75 % and 82 %) were categorised into the same WHO free sugars category with most (87 % and 95 %) correctly identified as having < 10 %EFS in line with the WHO recommendation. CONCLUSIONS: The SMILE-FSS has good internal validity and can be used in research and practice to estimate young Australian children's FSI and compare to the WHO free sugars guidelines to identify those 'at risk'.

AIMS: To quantify the impact of life course income trajectories on periodontitis in adulthood. MATERIALS AND METHODS: Data from the 1982 Pelotas Birth Cohort Study, Brazil, were used. Information on family income was collected at birth and ages 15, 19, 23 and 30 years. Group-based trajectory modelling was used to identify income trajectories. Periodontal measures were assessed through clinical examination at age 31. Log-Poisson regression models were used to estimate prevalence ratios (PRs) of any and moderate/severe periodontitis, as outcomes. RESULTS: Prevalence of any periodontitis and moderate/severe periodontitis was 37.3% and 14.3% (n = 539). Income trajectories were associated with prevalence of moderate/severe periodontitis. Adjusted PR in participants in low and variable income trajectory was 2.1 times higher than in participants in stable high-income trajectory. The unadjusted association between income trajectories and prevalence of any periodontitis was explained by the inclusion of behavioural and clinical variables in the model. CONCLUSIONS: Low and variable life course income increased the prevalence of moderate/severe periodontitis at age 31 years. The findings may inform programmes in identifying and targeting potentially at-risk groups during the life course to prevent periodontitis.

Objective The association between and commonality of risk factors for poor self-rated oral health (SROH) and general health (SRGH) among new mothers has not been reported. The purpose of this paper is to assess the commonality of risk factors for poor SROH and SRGH, and self-reported obesity and dental pain, among a population-based sample of new mothers in Australia. It also investigated health conditions affecting new mothers' general health. Methods Data collected at baseline of a population-based birth cohort was used. Mothers of newborns in Adelaide were approached to participate. Mothers completed a questionnaire collecting data on socioeconomic status (SES), health behaviours, dental pain, SROH, self-reported height and weight and SRGH. Analysis was conducted sequentially from bivariate to multivariable regression to estimate prevalence rate (PR) of reporting poor/fair SROH and SRGH. Results of the 1895 new mothers, some 21 and 6% rated their SROH and SRGH as poor/fair respectively. Dental pain was associated with low income and smoking status, while being obese was associated with low SES, low education and infrequent tooth brushing. SROH and SRGH was associated with low SES, smoking, and dental pain. SROH was also associated with SRGH [PR: 3.06 (2.42-3.88)]. Conclusion for practice There was a commonality of factors associated with self-rated oral health and general health. Strong associations between OH and GH were also observed. Given the importance of maternal health for future generations, there would be long-term societal benefit from addressing common risk factors for OH and GH in integrated programs.

We aimed to estimate hypothetical effects of habits (smoking, alcohol consumption, and fat and carbohydrates consumption) combined with diet-induced overweight/obesity on the risk of periodontitis. The risk of any periodontitis, moderate/severe periodontitis, and the combination of bleeding on probing (BOP) and clinical attachment loss (CAL) was estimated using the parametric g-formula in adults aged 31 years from the 1982 Pelotas Birth Cohort in Brazil. Individuals in this cohort have been followed since birth. Hypothetical conditions were set independently for each risk factor and in combination for the entire population. A total of 539 participants had oral examinations in 2013. The cumulative 31-year risk under no intervention was 33.3% for any periodontitis, 14.3%, for moderate/severe periodontitis, and 14.7%, for BOP and CAL. According to our statistical approach, diet-induced overweight/obesity increased the risk of all outcomes: 11% (overweight) and 22% (obesity) higher risk of periodontitis; 12% (overweight) and 27% (obesity) higher risk of moderate/severe periodontitis; 21% (overweight) and 57% (obesity) higher risk of CAL and BOP. When overweight/obesity was combined with other unhealthy habits, the risk was even greater. Our findings suggest that the combination of diet-induced obesity with other risk factors may increase the risk of periodontitis. Further research in the field is required to corroborate our study.

The objective of this study was to investigate differences in self-perceived and dentist-determined treatment need in Australian-born and migrant residents of Australia. Participants in the National Survey of Adult Oral Health 2004-06 were categorized into six groups according to country of birth. Interview and examination data were used to analyze differences between self-perceived and the 'gold standard' examiner-determined treatment need, and to compare the accuracy of self-reporting according to country of birth. Self-reported treatment needs, defined as the need for a restoration and/or extraction, were cross-tabulated with clinically observed conditions and compared using a multivariable logistic regression model. Concordance between self-reported and clinically-determined treatment need differed significantly for migrants from Europe and the UK and Australian-born individuals. In the logistic regression model, stratification according to examiner-determined treatment need revealed significantly greater reporting of treatment need by Asian-born migrants than by the Australian-born reference group. The results of this study demonstrate that self-perceived treatment need was less than the examiner-determined findings in European and UK migrant groups and Australian-born individuals. Additionally, Asian migrants were more likely than Australian-born individuals to over-report treatment need for a filling and/or extraction.

OBJECTIVE: The study assessed longitudinal changes in the presentation of dental fluorosis and evaluated the impact of fluorosis on the perception of oral health among young adults. DESIGN AND SETTING: Prospective follow-up study during 2011-12 of a population-based study in South Australia conducted between 2003 and 2004. PARTICIPANTS: 8-13-year-old children initially examined in 2003 and 2004. MAIN OUTCOMES: Dental fluorosis was assessed with the Thylstrup and Fejerskov (TF) Index. The impact on perceptions of oral health by the study participants and their parents was assessed with the Global Rating of Oral Health (GROH). Pairwise comparative analysis of the presentation of fluorosis was conducted at the individual and tooth levels. Multivariable models of changes in fluorosis were generated. An ordinal logistic regression model was used to evaluate the association between GROH with dental fluorosis, caries and other factors. RESULT: A total of 314 participants completed the follow-up questionnaires and dental examination. Over 60% of teeth scored as TF 1 at baseline were scored as TF 0 at follow-up; 66% of teeth scored as TF 2 or 3 at baseline were scored as TF 0 or 1 at follow-up. In multivariable models, changes in fluorosis were not significantly associated with socio-economic factors or oral health behaviours, confirming that they were the result of a natural process. Perceptions of poor oral health were significantly associated with the number of untreated decayed tooth surfaces at follow-up, but not with fluorosis. CONCLUSION: Very mild and mild dental fluorosis diminished with time. Dental fluorosis did not have a negative impact on perceptions of oral health.

AIM: This study aimed to conduct a systematic review assessing the effects of weight gain on the incidence of periodontitis in adults. METHODS: Electronic searches in four databases were performed up to and including February 2015. Only prospective longitudinal studies assessing the association between weight gain and the incidence of periodontitis in adults were eligible to be included in this study. All studies should state a clear description of nutritional status (Body Mass Index; Waist Circumference) as well as the case definition of periodontitis. Pooled relative risks (RR) for becoming overweight and obese on the incidence of periodontitis were estimated by meta-analysis. Quality was assessed with the Newcastle-Ottawa scale for cohort studies. RESULTS: Five articles were included in this review and meta-analysis with 42,198 subjects enrolled. Subjects who became overweight and obese presented higher risk to develop new cases of periodontitis (RR 1.13; 95%CI 1.06-1.20 and RR 1.33 95%CI 1.21-1.47 respectively) compared with counterparts who stayed in normal weight. CONCLUSIONS: A clear positive association between weight gain and new cases of periodontitis was found. However, these results are originated from limited evidence. Thus, more studies with longitudinal prospective design are needed.

BACKGROUND: Dental caries remains the most prevalent chronic condition in children and a major contributor to poor general health. There is ample evidence of a skewed distribution of oral health, with a small proportion of children in the population bearing the majority of the burden of the disease. This minority group is comprised disproportionately of socioeconomically disadvantaged children. An in-depth longitudinal study is needed to better understand the determinants of child oral health, in order to support effective evidence-based policies and interventions in improving child oral health. The aim of the Study of Mothers' and Infants' Life Events Affecting Oral Health (SMILE) project is to identify and evaluate the relative importance and timing of critical factors that shape the oral health of young children and then to seek to evaluate those factors in their inter-relationship with socioeconomic influences. METHODS/DESIGN: This investigation will apply an observational prospective study design to a cohort of socioeconomically-diverse South Australian newborns and their mothers, intensively following these dyads as the children grow to toddler age. Mothers of newborn children will be invited to participate in the study in the early post-partum period. At enrolment, data will be collected on parental socioeconomic status, mothers' general and dental health conditions, details of the pregnancy, infant feeding practice and parental health behaviours and practices. Data on diet and feeding practices, oral health behaviours and practices, and dental visiting patterns will be collected at 3, 6, 12 and 24 months of age. When children turn 24-30 months, the children and their mothers/primary care givers will be invited to an oral examination to record oral health status. Anthropometric assessment will also be conducted. DISCUSSION: This prospective cohort study will examine a wide range of determinants influencing child oral health and related general conditions such as overweight. It will lead to the evaluation of the inter-relationship among main influences and their relative effect on child oral health. The study findings will provide high level evidence of pathways through which socio-environmental factors impact child oral health. It will also provide an opportunity to examine the relationship between oral health and childhood overweight.

Foods and beverages high in free sugars can displace healthier choices and increase the risk of weight gain, dental caries, and noncommunicable diseases. Little is known about the intake of free sugars across early childhood. This study aimed to examine the longitudinal intake from 1 to 5 years of free sugars and identify the independent maternal and child-related predictors of intake in a cohort of Australian children participating in the Study of Mothers' and Infants' Life Events Affecting Oral Health (SMILE). Free sugars intake (FSI) was previously estimated at 1, 2, and 5 years of age, and three distinct FSI trajectories were determined using group-based trajectory modelling analysis. This study utilized multinomial logistic regression to identify the maternal and child-related predictors of the trajectories. The risk of following the 'high and increasing' trajectory of FSI compared to the 'low and fast increasing' trajectory was inversely associated with socio-economic disadvantage (aRRR 0.83; 95% CI 0.75-0.92; p < 0.001), lower for females (aRRR 0.56; 95% CI 0.32-0.98; p = 0.042), and higher in children with two or more older siblings at birth (aRRR 2.32; 95% CI 0.99-5.42; p = 0.052). Differences in trajectories of FSI were evident from an early age and a high trajectory of FSI was associated primarily with socio-economic disadvantage, providing another example of diet quality following a social gradient.

BACKGROUND: Simplified periodontal therapy might be a pragmatic strategy for public health programmes targeting Indigenous Australian adults. The objective of this randomized controlled trial was to evaluate oral health effects of single-visit, non-surgical periodontal therapy compared to no treatment. METHODS: This parallel-group, randomized, open label clinical trial enrolled 273 Indigenous Australians aged ≥18 years with periodontitis. Intervention participants received full-mouth periodontal scaling and root planing during a single visit while the control group received no treatment. Endpoints were summary variables derived from clinical assessments of probing depth, clinical attachment loss, plaque, calculus and gingival bleeding before treatment and 3 months later. RESULTS: Endpoints could be calculated for 169 participants with follow-up data. Compared to the control group, there were statistically significant reductions in extent of shallow pockets: PD ≥4 mm (mean difference -2.86, [95% CI -5.01 to -0.71], p = 0.009) and gingival bleeding (mean difference -0.25, [95% CI -0.43 to -0.08], p = 0.005) but not deeper pockets PD ≥5 mm (mean difference -0.48, [95% CI -1.78 to 0.82], p = 0.468) or plaque scores. CONCLUSIONS: Periodontal therapy produced improvements in shallow periodontal pockets and measures of gingival bleeding in these Indigenous Australians.

OBJECTIVES: Child oral health is a result of interactions between multilevel influences within a complex system. Understanding those interactions informs conceptualizing a socioecological framework of important influences on oral health. This paper aimed to present a scoping review on the determinants of dental caries and their interactions in childhood and adolescence. METHODS: The two review questions were as follows: Which factors are determinants of child dental caries? and, How do determinants interact within and across socioecological levels? The three main electronic databases for biomedical records, PubMed, Web of Science and Scopus were searched, followed by reference check. The search and screening/selection procedures followed an a priori strategy and inclusion/exclusion criteria were specified in advance. The main components of the strategy were participants, concept and context. Following the final selection, eligible studies were assessed with quality appraisal tools for the risk of methodologic biases. Determinants reported in the included studies were then assigned to the micro-, meso-, exo- or macro-systems levels in a socioecological framework. Interactions between determinants were also identified and reported. RESULTS: A total of 100 studies were included after removal of duplicates, screening on the title/abstracts and full-text assessment among 3313 records initially identified. A higher number of studies included were cross-sectional studies published in recent years. The majority of determinants found to influence child dental health were assigned to microsystem level within the framework. However, determinants were found at all levels and interactions were reported within and between socioecological levels. Determinants identified in the scoping review represent factors at different socioecological levels that influence child oral health. CONCLUSION: Application of a socioecological model through a complex systems approach should lead to valid and robust progress towards practical solutions for better child oral health globally.

OBJECTIVES: To investigate the association between trajectories of free sugars intake during the first five years of life and dental caries experience at five years. METHODS: Data from the SMILE population-based prospective birth cohort study, collected at one, two and five years old, were used. A 3-days dietary diary and food frequency questionnaire were used to estimate free sugars intake (FSI) in grams. The primary outcomes were dental caries prevalence and experience (dmfs). The Group-Based Trajectory Modelling method was used to characterize three FSI trajectories ('Low and increasing'; 'Moderate and increasing'; and 'High and increasing'), which were the main exposures. Multivariable regression models were generated to compute adjusted prevalence ratios (APR) and rate ratios (ARR) for the exposure, controlling for socioeconomic factors. RESULTS: The prevalence of caries was 23.3%, with a mean dmfs of 1.4, and a median of 3.0 among those who had caries. There were clear gradients of caries prevalence and experience by the FSI trajectories. The 'High and increasing' had an APR of 2.13 (95%CI 1.23-3.70) and ARR of 2.77 (95%CI 1.45-5.32) against the 'Low and increasing'. The 'Moderate and increasing' group had intermediate estimates. A quarter of the caries cases could have been prevented if the whole study sample had been in the 'Low and increasing' FSI trajectory. CONCLUSION: A sustained, high trajectory of FSI from a young age was positively associated with child dental caries. Measures to minimise consumption of free sugars must commence early in life. CLINICAL SIGNIFICANCE: The study has provided high level evidence to inform clinicians' decisions in promoting a healthy dietary pattern for young children.

OBJECTIVE: The objective of this study was to evaluate associations between patterns of infant formula feeding and dental fluorosis and caries in a representative sample of Australian children. METHODS: A population-based study gathered information on fluoride exposure in early childhood. Information on infant formula feeding and fluoridation status was used to group children: three groups in nonfluoridated areas (formula nonuser, user for ≤6 months, and user for 6+ months) and four groups in fluoridated areas (nonuser, user with nonfluoridated water, user with fluoridated water for ≤6 months, and user with fluoridated water for 6+ months). Children aged 8-13 years were examined for fluorosis using the Thylstrup and Fejerskov (TF) Index. Primary tooth caries experience recorded at age 8-9 years was extracted from clinical records. Fluorosis cases were defined as having TF 1+ on maxillary incisors. Fluorosis prevalence and primary caries experience were compared across formula user groups in multivariable regression models adjusting for other factors. RESULTS: Total sample was 588 children. Children in fluoridated areas had higher prevalence of very mild to mild fluorosis, but lower caries experience than those in nonfluoridated areas. Among children in nonfluoridated areas, formula users for 6+ months had significantly higher prevalence of fluorosis compared with nonusers. There was no significant difference in fluorosis prevalence among the formula users in fluoridated areas. Among children in fluoridated areas, formula users with nontap water had higher caries experience. CONCLUSION: Infant formula use was associated with higher prevalence of fluorosis in nonfluoridated areas but not in fluoridated areas. Type of water used for reconstituting infant formula in fluoridated areas was associated with caries experience.

OBJECTIVES: To investigate the trajectory of maternal intake of sugar-sweetened beverages (SSB) during the first five years of their child's life and its effect on the child's dental caries at five years-of-age. METHODS: This is an ongoing prospective population-based birth cohort study in Adelaide, Australia. Mothers completed questionnaires on their SSB intake, socioeconomic factors and health behaviors at the birth of their child and at the ages of one, two and five years. Child dental caries measured as decayed, missing, or filled tooth surfaces was collected by oral examination. Maternal SSB intake was used to estimate the trajectory of SSB intake. The trajectories then became the main exposure of the study. Dental caries at age five years were the primary outcomes. Adjusted mean- and prevalence-ratios were estimated for dental caries, controlling for confounders. RESULTS: 879 children had dental examinations at five years-of-age. Group-based trajectory modeling identified three trajectories of maternal SSB intake: 'Stable low' (40.8%), 'Moderate but increasing' (13.6%), and 'High early' trajectory (45.6%). Multivariable regression analysis found children of mothers in the 'High early' and 'Moderate but increasing' groups to have greater experience of dental caries (MR: 1.37 (95%CI 1.01-1.67), and 1.24 (95%CI 0.96-1.60) than those in the 'Stable low' trajectory, respectively. CONCLUSION: Maternal consumption of SSB during pregnancy and in the early postnatal period influenced their offspring's oral health. It is important to create a low-sugar environment from early childhood. The results suggest that health promotion activities need to be delivered to expecting women or soon after childbirth.

This study examines the impact of longitudinal dietary trajectories on obesity and early childhood caries (ECC) in preschool children in Australia. Mother-infant dyads from the Healthy Smiles Healthy Kids study were interviewed at 4 and 8 months, and 1, 2, and 3 years of age. Children underwent anthropometric and oral health assessments between 3 and 4 years of age. Multivariable logistic regression and negative binomial regression analysis were performed for the prevalence of overweight and obesity, and the number of tooth surfaces with dental caries, respectively. The intake of core, discretionary, and sugary foods showed distinct quadratic (n = 3) trajectories with age. The prevalence of overweight or obesity was 10% (n = 72) and that of early childhood caries (ECC) was 33% (mean decayed, missing, and filled tooth surfaces (dmfs) score: 1.96). Children with the highest trajectories of discretionary foods intake were more likely to be overweight or obese (adjusted OR: 2.51, 95 %CI: 1.16-5.42). Continued breastfeeding beyond 12 months was associated with higher dmfs scores (adjusted IRR: 2.17, 95 %CI: 1.27-3.73). Highest socioeconomic disadvantage was the most significant determinant for overweight or obesity (adjusted OR: 2.86, 95 %CI: 1.11-7.34) and ECC (adjusted IRR: 2.71, 95 %CI: 1.48-4.97). Targeted health promotion interventions should be designed to prevent the incidence of two highly prevalent conditions in preschool children.

AIMS: Evidence suggests there are geographical variations in child oral health and this has prompted research into determinants of that variation. This study aimed to investigate factors attributable to the difference in child oral health between urban and rural areas in Australia. METHOD: Data were from the National Child Oral Health Study 2012-14, a population-based study of 5- to 14-year-old children, who underwent oral epidemiological examinations by trained examiners. Caries prevalence (dmfs/DMFS > 0) and experience (dmfs/DMFS count) in the primary dentition (5- to 8-year-old) and permanent dentition (9- to 14-year-old) were calculated. Children were grouped by residential location (urban or rural areas). A parental questionnaire collected information on family socio-economic factors, and individual health behaviours (dental access, sugar consumption and toothbrushing). Residential history was used to calculate lifetime exposure to water fluoridation (WF). Analyses were weighted to produce population-representative estimates. The primary outcomes were assessed separately for the two groups in regression models with robust standard error estimation to estimate prevalence ratios and mean ratios and their 95% confidence intervals. Population Attributable Fractions were calculated using the population distribution of the exposures and their adjusted estimates. RESULTS: 10 581 5- to 8-year-old and 14 041 9- to 14-year-old children were included. Caries prevalence was higher in rural than in urban areas. In multivariable models, exposure to fluoridation, reason for dental visit and consumption of sugary beverages were consistently associated with caries prevalence and experience. WF coverage attributed to differences in caries prevalence (10% vs 21%) and experience (14% vs 35%) in the permanent dentition. High consumption of sugary beverages attributed to a higher primary and permanent dental caries experience in rural than in urban areas. Dental access was also attributed to the differences between the two areas. CONCLUSION: Factors at both community and individual levels attributed to the observed differences in child caries prevalence and experience between urban and rural areas.
RESUMO
The National Study of Adult Oral Health (NSAOH) 2017-18 aimed to collect data on population oral health status of the Australian adult population. This complex nation-wide project required reliable data collection procedures. The NSAOH 2017-18 Oral Epidemiological Examination Protocol has been developed based on internationally accepted examination procedures. Examiners have been trained and calibrated in using the protocol. Details of the clinical examination components are provided. Examiner reliability has been tested and presented.

BACKGROUND: The use of fluoride involves a balance between protection against caries and risk of dental fluorosis. Prevalence and trend of dental fluorosis in the adult population are not frequently reported. OBJECTIVE: To describe the prevalence of dental fluorosis in the Australian adult population. METHOD: Data from the National Study of Adult Oral Health (NSAOH) 2004-06 and 2017-18 were used. Prevalence of fluorosis was reported using data from the NSAOH 2017-18. Case definitions of fluorosis were as follows: having a TF score of 2+ (TF2+) or a TF score of 3+ (TF3+) on one or more maxillary central incisors. Synthetic cohorts were constructed by year of birth allowing for time trend analysis. RESULTS: One in ten Australian adults were found to have dental fluorosis at TF2+. The prevalence of TF3 + was low. Time trend analysis revealed an increase in the prevalence and severity of fluorosis among those born during 1970s to 1980s decade. Such prevalence declined among those who were born after measures were introduced in early 1990s to reduce exposure to discretionary fluorides. CONCLUSION: The prevalence of dental fluorosis in the Australian adult population was found to be related to population-level changes in fluoride exposure.
