Prevalence and Associated Factors of Tooth Erosion in 8 -12-Year-Old Brazilian Schoolchildren.

Abstract
This study estimated the prevalence, distribution and associated factors of tooth erosion in Brazilian schoolchildren. A cross-sectional study was carried out in a representative sample of children aged 8-12-years-old from public and private schools. Six calibrated examiners assessed tooth erosion (O'Sullivan index) and other oral conditions (dental trauma, enamel defects, plaque, dental caries and dental crowding). Socio-demographic and behavioral data were collected using questionnaires. Interviews were conducted in children and in parents. Data were analyzed using Poisson regression model considering the cluster sample (Prevalence Ratio-PR; 95% Confidence Interval-CI). A total of 1,210 children participated and were examined. Tooth erosion was observed in 25.1% of the children. Lesions were mostly observed in enamel and less than a half of the buccal surface was affected. The type of school and age were significant associated with higher prevalence of tooth erosion and dental crowding was associated with less probability of tooth erosion significantly. Acidic food or drinks were not associated with dental erosion. The prevalence of tooth erosion in the studied population was high. Erosive lesions were not severe, confined in enamel. Tooth erosion was associated with age, type of school, socioeconomic level and dental crowding.
