RESUMO
Aim: This study presents the prevalence of dental caries and its relation to the quality of life ofadolescents according to the access to dental health services. Methods: Two hundred and fifty-sixadolescents between 15 and 19 years of age participated in the study; they were all enrolled inpublic schools in a countryside municipality of the São Paulo State. Data related to dental carieswere evaluated by the DMFT Index, and OHIP-14 was used for evaluating the quality of life. MannWhitney and Spearmann correlation tests were also used (p<0.05). Results: A DMFT of 3.09(±3.30) was found with a higher prevalence among the adolescents who used public dental services(3.43±3.34) compared with those who used private services (2.94±3.28). A statistically significantrelationship between the decay component of DMFT with physical pain (0.020), physical disability(0.002) and quality of life (0.017) was verified. Conclusions: A low prevalence of dental caries wasobserved, and it was higher in adolescents who used public oral health services rather than privateones, evidencing the low influence of oral health on the quality of life of the participants.
