There are no prospective studies investigating the effects of sugar-related feeding practices on changes in dental caries from early childhood to young adulthood. The aim of this study was to assess whether sugar-related feeding practices affect dental caries between the ages of 6 and 18 y. This birth cohort study was initiated in 1993 in Pelotas, Brazil. There were 3 dental clinical assessments; at ages 6 y (n = 359), 12 y (n = 339), and 18 y (n = 307). Sugar-related feeding practices were assessed at ages 4, 15, and 18 y. Covariates included sex and life course variables, such as family income, breast-feeding, mother's education, regularity of dental visit, and child's toothbrushing habits. Group-based trajectory analysis was performed to characterize trajectories of time-varying independent variables that had at least 3 time points. We fitted a generalized linear mixed model assuming negative binomial distribution with log link function on 3-time repeated dental caries assessments. One in 5 participants was classified as "high" sugar consumers, and nearly 40% were "upward consumers." "Low consumers" accounted for >40% of the sample. High and upward sugar consumers had higher dental caries prevalence and mean DMFT in all cohort waves when compared with low sugar consumers. Caries occurred at a relatively constant rate over the period of study, but in all sugar consumption groups, the increment of dental caries was slightly higher between ages 6 and 12 y than between 12 and 18 y. Adjusted analysis showed that dental caries increment ratio between ages 6 and 18 y was 20% and 66% higher in upward and high sugar consumer groups as compared with low consumers. The higher the sugar consumption along the life course, the higher the dental caries increment. Even the low level of sugar consumption was related to dental caries, despite the use of fluoride.

OBJECTIVE Identifying, through a systematic literature review, evidence of a possible association between obesity and dental caries. METHODS A search of articles published between 2005 and January 2012 was performed in the Medline/PubMed, LILACS and Web of Science databases. The quality of scientific evidence of the selected articles was assessed by the items proposed for observational studies in the Downs & Black instrument. RESULTS Initially, 537 references were found; after checking the titles and abstracts by two independent researchers, twenty-eight articles were selected for complete reading. Ten of them that assessed the primary and/or permanent dentition observed a positive association between obesity and dental caries and one study found an inverse association. According to the Downs & Black classification, thirteen articles with good scientific evidence were found. CONCLUSIONS The present review did not find sufficient evidence regarding the association between obesity and dental caries, and it did not clarify the possible role of diet and other possible effect modifiers on this association.

The aim of this study was to estimate self-reported prevalence of edentulism, severe tooth loss and lack of functional dentition in elders, and to identify potential associated factors. A population based cross-sectional study was carried out with 1,451 elders (≥60 years), in Pelotas, RS, Brazil. Crude and adjusted prevalence ratios were estimated using Poisson regressions. The prevalence of edentulism, severe tooth loss and lack of functional dentition was 39.3%, 60.9% and 82.7%, respectively. The factors positively associated with tooth loss in the three-degree severity were sex (females), older individuals, low familial income, low level of schooling and having the last dental visit longer than 24 months ago. The high prevalence of tooth loss in its different degrees of severity and the association with preventable factors highlight the need of programs focused on elders, emphasizing the prevention of tooth loss and need for prosthetic rehabilitation.

The low prevalence of use of dental services among elderly attending Family Health Units in Pelotas, especially among those with poor self-assessed general health, lower education level, and without teeth, indicate the need for public policies to improve social indicators and general health.

The findings of the present study underscore the need for public policies aimed at reducing social inequalities and providing adequate dental treatment to improve OHRQoL among elderly individuals.

ObjectiveEstimate the prevalence of dental caries based on clinical examinations and self-reports and compare differences in the prevalence and effect measures between the two methods among 18-year-olds belonging to a 1993 birth cohort in the city of Pelotas, Brazil.MethodData on self-reported caries, socio-demographic aspects and oral health behaviour were collected using a questionnaire administered to adolescents aged 18 years (n = 4041). Clinical caries was evaluated (n = 1014) by a dentist who had undergone training and calibration exercises. Prevalence rates of clinical and self-reported caries, sensitivity, specificity, positive and negative predictive values, absolute and relative bias, and inflation factors were calculated. Prevalence ratios of dental caries were estimated for each risk factor.ResultsThe prevalence of clinical and self-reported caries (DMFT>1) was 66.5% (95%CI: 63.6%–69.3%) and 60.3% (95%CI: 58.8%–61.8%), respectively. Self-reports underestimated the prevalence of dental caries by 9.3% in comparison to clinical evaluations. The analysis of the validity of self-reports regarding the DMFT index indicated high sensitivity (81.8%; 95%CI: 78.7%–84.7%) and specificity (78.1%; 95%CI: 73.3%–82.4%) in relation to the gold standard (clinical evaluation). Both the clinical and self-reported evaluations were associated with gender, schooling and self-rated oral health. Clinical dental caries was associated with visits to the dentist in the previous year. Self-reported dental caries was associated with daily tooth brushing frequency.ConclusionsBased on the present findings, self-reported information on dental caries using the DMFT index requires further studies prior to its use in the analysis of risk factors, but is valid for population-based health surveys with the aim of planning and monitoring oral health actions directed at adolescents.

OBJECTIVETo analyze the effectiveness of educational interventions performed in health services in the improvement of clinical behaviors and outcomes in oral health.METHODSWe have carried out a systematic review of the literature searching the PubMed, Lilacs, and SciELO databases. We have included studies that have investigated interventions performed by health professionals working in health services and who have used educational actions as main approach to improve behavioral and clinical outcomes in oral health.RESULTSThe search amounted to 832 articles and 14 of them met all the inclusion criteria. Five studies have only exclusively evaluated the effectiveness of interventions on caries reduction, three have exceptionally evaluated oral health behaviors, and the other articles have evaluated the effectiveness of interventions for both clinical outcomes (dental caries and periodontal conditions) and behaviors in oral health. Most of the studies (n = 9) were based on randomized controlled trials; the other ones have evaluated before and after the intervention. Five studies have reported a significant reduction of dental caries, and five of the six studies evaluating behavioral outcomes have found some positive change.CONCLUSIONSMost studies evaluating behavioral and periodontal outcomes have shown significant improvements in favor of interventions. All studies evaluating caries have shown a reduction in new lesions or cases of the disease in the groups receiving the interventions, although only five of the eleven articles have found a statistically significant difference. Educational interventions carried out by health professionals in the context of their practice have the potential to promote oral health in the population.

Objective The aim of the present study was to investigate oral health‐related quality of life (OHRQoL) and determine associations with demographic, socio‐economic and oral health variables at two evaluation times (2009 and 2015) among older adults assisted by Family Health Units in the Brazil. Methods A longitudinal study was conducted involving the evaluation (2009) and re‐evaluation (2015) of 161 older adults (≥60 years of age). Demographic, socio‐economic and general health variables were collected using a standardised questionnaire. Clinical oral health variables were also collected. OHRQoL was measured using the Oral Health Impact Profile‐14 (OHIP‐14). Multiple regression analysis was employed for the evaluation of OHRQoL considering the variables from the two evaluations. Results The severity of impact (mean OHIP‐14) was 9.12 (SD: 10.81) in 2009 and 8.50 (10.52) in 2015. The greatest impact regarded the psychological discomfort domain at both evaluations (28.8% in 2009 and 22.9% in 2015). In the adjusted multiple linear regression, the mean OHIP‐14 score increased 4.8 points (95% CI: 0.11‐9.49) among individuals who experienced tooth loss between the two evaluations in comparison with those who maintained the same number of teeth. An increase in the OHIP‐14 score occurred between 2009 and 2015 among 40.6% of the older adults. Conclusions The findings of the present study reveal that the oral health status of older adults exerts an influence on OHRQoL, indicating the need for oral health policies directed at this portion of the population.
