Abstract

Introduction: Dental erosion is a condition resulting from the irreversible dissolution of mineralized portion of the teeth, being recognized in modern society, as an important cause of loss of tooth structure. In this sense, the aim of this study was to determine the prevalence and association with sociodemographic and dietary habits in adolescents 15-19 years in the city of Campina Grande - PB, Brazil. Methods: A cross-sectional study was conducted on a stratified sample of 675 school adolescents 15-19 years of both sexes, using the index proposed by O'Sullivan, modified for use in maxillary incisors and first molars. Clinical data were evaluated by two calibrated dentists (Kappa intra-and inter = 0.74 and 0.82.) For data analysis we used the SPSS ® (Statistical Package for the Social Sciences) was held descriptive statistics (absolute distribution, percentage, mean and standard deviation) and analytical (Chi-square). The significance level was 5%. Results: The prevalence of dental erosion was 21%, and the upper central incisors (50.5%) and the upper lateral incisors (40.2%), the elements most affected. The buccal showed greater impairment (51.4%) and 67.8% of teeth with dental erosion had more than half the surface of the affected area. Most lesions restricted to the enamel (93.5%) and showing a symmetrical distribution. There were no statistically significant differences between the occurrence of dental erosion with gender, age, socioeconomic status, self-reported race and diet (p> .05). Conclusion: A high prevalence of dental erosion in its early stages was observed among adolescents, mainly affecting the labial surface of the upper anterior elements, and that was not statistically associated with sociodemographic and dietary habits.
