Dental caries and the severity (depth) and area of erosions of tooth substance were studied in 11 bulimic subjects and 22 matched controls. Erosions were seen in 69% of the bulimics' teeth and in only 7% of the controls' (p less than 0.001). Depth of penetration was greater in the bulimics, extending even into the pulp, and the area of erosion was also larger. Scores for dental caries were higher in bulimics (mean DMFS 27.9, median 36) than in controls (mean DMFS 19.1, median 13.5), although the difference was not statistically significant. This study suggests that when erosions are present on the lingual surfaces of maxillary anterior teeth, as well as on the buccal surfaces of maxillary canines, premolars, and maxillary incisors, a diagnosis of bulimia is likely. Patients with these signs should be referred for medical help.
