Dental erosion and its association with eating disorders and gastroesophageal reflux disease in adolescent students
Main Article Content
Abstract
Introduction: Dental erosion is a common problem in adolescents and may be associated with eating disorders and Gastroesophageal Reflux Disease. Objective: To determine the prevalence of dental erosion and its association with the risk of eating disorders and symptoms of gastroesophageal reflux disease in adolescent students. Methods: This cross-sectional, analytical, school-based study had a sample of 430 students of both sexes, aged 10 to 19 years, from public schools in inland Brazil. Adolescents undergoing orthodontic treatment and those who had some type of disability that prevented their participation were excluded. A self-administered questionnaire was applied to the participants, consisting of sociodemographic characteristics, food attitudes test, and symptoms of gastroesophageal reflux disease, followed by the Basic Erosive Wear Examination (BEWE) for clinical diagnosis of dental erosion. Data were analyzed with Pearson's chi-square test, Fisher's exact test, and Mann-Whitney test, with a margin of error set at 5%. Results: Dental erosion was found in 46.3% of adolescents, and 24.7% were at risk for eating disorders. As for gastroesophageal reflux disease, the mean (5.38±6.68) and median (4.59±5.34) were higher in students with dental erosion, without a significant association. Conclusion: This study showed a high prevalence of dental erosion among adolescents, predominantly on enamel.
