Impacto de erosão dentária na qualidade de vida relacionada à saúde bucal de escolares

Abstract

Background: Prevalence data about dental erosion has attracted increasing attention in dental community. However, none study has addressed the impact of this condition on child oral health-related quality of life (COHRQoL). Aim: We assessed whether dental erosion impacted COHRQoL. Material and Methods: A Crosssectional study of a multistage random sample of 944, 11-to 14-years-old Brazilians schoolchildren was examined for recording the prevalence and severity of dental erosion (O Sullivan), dental caries and dental trauma by two examiners. Children completed the Brazilian version of Child Perceptions Questionnaire (CPQ11-14) and data about socioeconomic variables of the target population were collected by means of a structured questionnaire. Poisson regression model using robust variance were performed to assess the association between the predictor variables and the outcomes. Results: Prevalence of dental erosion (7.2%) and severity of dental erosion were low. Poisson regression models showed a distinct gradient in mean CPQ 11-14 scores by socioeconomic indicators and clinical conditions. Children with dental erosion, with low levels of severity, did not reported higher means in the total scores or domains of CPQ11-14. Conclusion: Presence of dental erosion, in low levels of severity, does not have a significant negative impact on the child s perception of oral health and on their daily performance.
