Influência do sangramento gengival na qualidade de vida relacionada à saúde oral de adolescentes

Abstract

Gingival bleeding has been associated with worse oral health-related quality of life (OHRQoL), however there is no studies showing influence of this condition longitudinally in adolescents. The aim of this study is evaluate the influence of gingival bleeding on OHRQoL of Brazilian adolescents. This longitudinal study consisted of a random sample in the city of Santa Maria, RS, Brazil. After two years follow-up, 743 adolescents were reassessed (response rate: 65.5%). The short form of Brazilian version of the Child Perceptions Questionnaire 11-14 (CPQ11-14) was applied in the adolescents to evaluate the OHRQoL. In addition, the parents/guardians answered a socioeconomic questionnaire. Gingival bleeding was assessed using the Community Periodontal Index. Data were analyzed using the Poisson regression model in the Stata 14.0 program. Prevalence of gingivitis in the baseline was considered the predictor for the OHRQoL in the second evaluation. Gingivitis at baseline was associated with CPQ 11-14 (RR: 1.07, 95% CI: 1.01-1.14) and with the emotional well-being domain (RR 1.17, 95% CI 1.04 -1.31). Sex, maternal schooling and family income were also associated with worse CPQ scores11-14. Therefore, gingivitis negatively impacts the adolescents’ OHRQoL, mainly those with worse socioeconomic status.
