This study assessed the association between self-reported oral health and the normative indices of dental caries in an adolescent population. This study is based on a 6-year data from a cohort, beginning in 2012, with 1,134 twelve-year-old adolescents. After three phases of data collection, 68% of the samples were followed up. Self-reported oral health was evaluated through the question: "Would you say that the health of your teeth, lips, jaws, and mouth is …?", and answers were categorized as "good" or "poor." Calibrated dentists examined clinical conditions using the decayed, missing, and filled teeth (DMFT) index. Statistical analysis was performed using multilevel logistic regression models, considering the dependence of those observed thrice and adjusted for demographic, socioeconomic, and dental visit variables. Adolescents who evaluated their oral health as poor had higher mean DMFT (OR: 1.35; CI95% 1.22-1.50). When evaluated separately, decayed (OR: 2.43; CI95% 1.83-3.23) and missing (OR: 3.94; CI95% 1.26-12.26) teeth also presented significant results, showing poor self-reported oral health associated with a higher mean. Adolescents' self-perceived oral health was associated with normative dental caries indices, and this association was maintained throughout adolescence.
