Lesões dentárias traumáticas e fatores individuais e contextuais associados entre adolescentes brasileiros: um estudo de base populacional

Abstract

The objective of this study was to evaluate traumatic dental injuries (TDIs) in adolescents participating in the São Paulo State Oral Health Survey (SBSP-15). Individual (sex, age, schooling, skin color, overjet and molar ratio) and contextual (size of cities and Municipal Human Development Index) predisposing variables, individual (monthly per capita income and type of dental service) and contextual (inhabitants/dentist ratio, Family Health Team coverage and mean family income) enabling components, individual (satisfaction with treatment and perception about teeth) and contextual (supervised brushing average, first dental appointments per tertile and exodonties per city) needs, as well as health behaviors were analyzed. Andersen's behavioral model instructed the data analysis. A multilevel logistic regression with fixed effects was performed to calculate the Odds Ratio (OR), with 95% confidence interval (CI). The prevalence of TDIs in adolescents was 1,42% (95%CI 0,94-2,13). Individual and contextual predisposing, enabling and need components and health behaviors were associated with TDIs. In the adjusted analysis, sex (OR=0,32; 95%CI 0,18-0,53), mean family income (OR=2,52; 95%CI 1,35-4,69), number of dental appointments (OR=0.40; 95%CI 0,19-0,84) and time of last dental visit (OR=2,64; 95%CI 1,46-4,77) remained significant concerning trauma.
