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.
Highlights
Social determinants of health such as socioeconomic status and family environmental characteristics have been linked to oral health in children and adolescents.[7,8]
It was verified that the three lowest powers of the test, given by 1- error type II, were 57, 64 and 72% for the covariates DMFT, childrens perception of their oral health and home ownership, respectively
The results considered only the variable selected by the stepwise method and, the probability of adolescents showing improvement in oral health-related quality of life (OHRQoL) was expressed by the formula: p= exp(−0.2151+0.7920*DMFT) 1+exp(−0.2151+0.7920*DMFT)
