It is characterized by binge eating with self-induced vomiting, laxative use, dieting, and exercise to prevent weight gain. Patients with bulimia are at risk for damage to the dental enamel and dentin as a result of repeated episodes of vomiting with chronic exposure to regurgitated acidic gastric contents. The lingual dental surfaces are most commonly affected. In severe cases, all surfaces of the teeth may be affected. Trauma to the oral and esophageal mucosa may also result from induced vomiting. The quantity, buffering capacity, and pH of both the resting and stimulated saliva are found to be reduced, and salivary gland enlargement, most commonly the parotid, may occur as well.
