Resumo Introdução A tendência de redução da cárie dentária tem sido constatada, apesar de maiores investigações sobre seu padrão e desenvolvimento serem ainda necessárias. Objetivo investigar a influência de variáveis clínicas, sociais e ambientais sobre a cárie em adolescentes de um município brasileiro com água fluoretada, no ano de 2018. Método Empregou-se uma amostra não probabilística de 277 adolescentes de 12 anos, de escolas públicas de Nova Friburgo, Rio de Janeiro, Brasil. Exames clínicos foram realizados por examinadores calibrados, para avaliação de cárie, doença periodontal e fluorose, sob critérios da Organização Mundial da Saúde (OMS). Questionários semiestruturados foram aplicados para coletar informações socioambientais. Resultados Indivíduos residentes em regiões com flúor na água em subdoses (OR=3,60, p=0,0006), e aqueles com baixa renda (OR =1,90, p=0,0444), com presença de gengivite (OR = 3,36; p = 0,0016) e cuja razão para a visita ao dentista foi para tratamento dentário (OR=2,41; 0,0203), apresentaram mais chances de terem cárie. Uma redução significativa (p<0,0001) nos índices de cárie foi observada entre 2012 (primeiro levantamento epidemiológico) e 2018. Conclusão A fluoretação das águas de abastecimento público, quando em níveis não adequados, assim como outras variáveis sociais e clínicas, podem influenciar o padrão de cárie nos adolescentes.

Abstract Background Although a trend towards dental caries reduction has been observed, further investigations on its pattern and development are still needed. Objective To investigate the influence of clinical, social and environmental variables on dental caries prevalence in adolescents from a Brazilian municipality supplied with fluoridated water in 2018. Method This study was conducted with a non-probabilistic sample of 277 adolescents aged 12 years of public schools in Nova Friburgo, state of Rio de Janeiro, Brazil. Clinical examinations were carried out by calibrated examiners to assess caries, periodontal disease, and fluorosis according to criteria of the World Health Organization (WHO). Semi-structured questionnaires were applied to record socio-environmental information. Results Individuals living in regions supplied with fluoridated water below the minimum required levels (OR=3.60, p=0.0006), with low income (OR=1.90, p=0.0444), presence of gingivitis (OR=3.36; p=0.0016), and whose reason for visiting the dentist was dental treatment (OR=2.41; p=0.0203) were more likely to have dental caries. A significant reduction (p<0.0001) in dental caries indexes was observed between 2012 and 2018. Conclusion Fluoridation of public water supply at unsuitable levels, as well as other social and clinical variables can influence the caries pattern in adolescents.

ABSTRACT Objective: To evaluate the association of oral health indicators and social variables on the frequency of visit to the dentist by persons with intellectual disability (ID). Material and Methods: The study comprised a sample consisting of 149 participants with ID, aged from 11 to 29 years, from non-governmental institutions. Semi-structured interviews were held to collect sociodemographic and psychosocial information with their parents/guardians, followed by oral health evaluations in accordance with World Health Organization criteria. Crude analyses and multiple analysis were conducted to test whether oral health indicators and social data were predictors of the visit to dental care services. Results: In the multiple logistic regression model, individuals with lower DMF-t (OR=3.13; 95% CI=1.40-6.97) and those with less crowded housing (OR=2.33; 95% CI=1.06-5.12) presented less frequency of visits to oral health services. Conclusion: DMFT and crowded housing are associated to the frequency of persons with intellectual disability to dental care as well as this outcome measure affects the oral health of persons with ID. Therefore, identifying limiting factors to dental care of persons with intellectual disability is needed so that this group can receive adequate attention.

Abstract The aim of this study was to evaluate the influence of the Brazilian School Health Program (SHP) on dental clinical disorders such as caries, gingivitis, and dental trauma as well as on the oral-health-related quality of life (OHRQoL) of adolescents in Nova Friburgo, RJ, Brazil. The study consisted of a non-probabilistic (convenience) sample comprising 319 12-year-old adolescents, both participants and non-participants of the SHP, for at least two years. Socio-demographic and OHRQoL questionnaires (CPQ11-14, the Child Perceptions Questionnaire) were applied as well as clinical examinations for caries, periodontal disease, and dental trauma following the World Health Organization (WHO) criteria by calibrated researchers. Mann-Whitney, chi-square tests, and multiple logistic regression models were used for the data analysis. Statistically significant differences were observed between the groups covered and not covered by the SHP for gingivitis (p = 0.0373) and OHRQoL on the social welfare subscale (p = 0.0265) and total scale (p = 0.0449) of CPQ11-14. Multivariate analysis showed that female adolescents were 1.74 times more likely to present a lower OHRQoL (OR = 1.74, 95%IC = 1.10–2.77, p = 0.0183) than males. In addition, non-SHP subjects were 1.56 times more likely to have poor OHRQoL (OR = 1.56, 95%IC = 0.94–2.59, p = 0.0873) than program participants. In conclusion, SHP positively influenced the OHRQoL of adolescents. However, follow-up studies are needed to verify the continued effectiveness of this Brazilian SHP in improving the oral health levels and quality of life of adolescents.

AIM: To identify the prevalence of dental caries in inland Brazilian adolescents, and to analyze the influence of socio-demographic and clinical variables, and access to dental service on caries experience.METHODS: This study had a non-probabilistic sample comprising 504 adolescents aged 12 years, attending public schools in the city of Nova Friburgo, mountain region of Rio de Janeiro, Brazil. The World Health Organization (WHO, 1997) criterion was used by previously calibrated examiners to report dental caries. Variables were obtained by means of a semi-structured questionnaire applied to the adolescents' parents.RESULTS: The D3MFT mean was 1.90 and the Significant Caries (SIC) Index was 4.54, mainly represented by the carious component. Multiple logistic regression analysis revealed that parents with over 8 years of schooling (OR=0.579), absence of pain (OR=0.396) and not visiting the dentist (OR=0.270) might suggest protective factors against the disease; the possible risk factors were male gender (OR=1.982) and pain, extraction and others were reasons for consultation (OR=2.435).CONCLUSIONS: Although the prevalence of caries was slightly below the national mean, polarization of the disease was clearly observed. Education and no access to the dentist led to protection against the disease. These results may contribute to planning of oral health actions directed towards this target population for the control of caries.
