Dental white spots associated with bulimia nervosa in orthodontic patients

Abstract

Bulimia nervosa is an eating disorder characterized by consuming a large amount of food in a short amount of time followed by an attempt to rid oneself of the food consumed (purging), typically by vomiting, taking a laxative, diuretic, or stimulant, and/or excessive exercise, because of an extensive concern for body weight. The frequent contact between teeth and gastric acid, in particular, may cause: severe dental erosion, perimolysis, or the erosion of tooth enamel and swollen salivary glands. Constant vomiting can lead to gastroesophageal reflux. The aim of this article is to report two cases of patients with severe dental demineralization associated with bulimia nervosa during orthodontic treatment. Diagnosis and prevention aspects are highlighted and discussed
