Behavioral eating disorders and their effects on oral health in adolescence

Abstract

Anorexia nervosa and bulimia nervosa are serious eating disorders that affect a significant number of adolescents and young adults. Individuals with anorexia nervosa tend to ignore or deny their excessive dieting and may present purging habits. The individual with bulimia nervosa spends great effort and time in compensating the effects of binge eating with dieting and fasting, self-inducing vomiting, utilization of laxatives or overexercising. The incidence of those behavioral disorders seems to be increasing, but there are no epidemiological data on that matter in Brazil. The dental practitioner has an important role in identifying these disorders since toothwear is very frequent due to the acidic oral environment caused by vomiting. The dentist can help to minimize the effects of anorexia and bulimia on the dentition. The objective of this study is to review the features of those behavioral eating disorders and to highlight the importance of being prepared to diagnose them and implement a comprehensive treatment of patients.
