ABSTRACT
Abstract The aim of the present study was to investigate the impact of oral diseases, socioeconomic status, and family environmental factors on changes in the perception of oral health-related quality of life (OHRQoL) in adolescents. A prospective cohort study was conducted in Juiz de Fora, Minas Gerais, Brazil, with a sample of 286 twelve-year-old adolescents from public and private schools, selected by means of multistage random sampling. The adolescents were clinically examined for dental caries experience (number of decayed, missing, and filled teeth - DMFT index), presence of bleeding, and orthodontic treatment needs. They were asked to complete the Brazilian version of the Child Perceptions Questionnaire (CPQ11-14). In addition, parents answered a questionnaire about their socioeconomic status and family environmental characteristics. After 3 years, the adolescents were contacted again to participate in the research. Logistic regression models, with explanatory variables assessed both individually and jointly, were used to determine which independent variables impacted longitudinally on OHRQoL. The final result demonstrated that only DMFT explained part of the response variability in CPQ11-14 scores. In conclusion, caries experience was an important predictor of OHRQoL in adolescents followed up for 3 years.

To evaluate socioeconomic, familiar and clinical risk variables associated to caries increment in the children's permanent dentition from seven to 10 years participating in a dental health program.Material and Methods:A sample of 301 children from nine public schools participated in the æAlways Smiling ProgramÆ took part in this study. They were evaluated for dental caries through dmft and DMF-T indexes along 2 years, and their parents completed a socio-environmental questionnaire containing questions on their income, education and family environment. Survival analysis using Kaplan-Meier method was used to evaluate the effect of the independent variables on caries increment.Results:We verified that socio-environmental variables were not associated with caries increment, while children with experience in primary dentition were 1.5 times more likely to develop caries in permanent dentition compared to those who did not have this experience.Conclusion:Schoolchildren presenting dental caries in primary dentition on baseline had higher risk of developing caries in permanent dentition and this variable should be taken in consideration by managers of dental health programs when prioritizing groups with higher care needs...
