OBJECTIVE
To determine the influence of oral hygiene practices and additional fluoride on erosive tooth wear in eating disorders. The proportional dietary intake of carbohydrates, fats, and proteins was also investigated.
METHODS
Tooth wear was measured with the use of the tooth wear index (TWI). All subjects completed a questionnaire on past dental history as well as a 1-week diet sheet. A total of 33 subjects participated in the study, 20 of whom were follow-ups, allowing the progress of dental erosion to be made. All subjects were referred from the Department of Clinical Psychology.
RESULTS
Oral hygiene practices between subjects with and without severe erosion were not significantly different. Only 8 bulimics spent more time brushing after vomiting than at other times. The pH of vomitus from 6 subjects ranged between 2.9 and 5.0, with a mean of 3.8, well below the critical pH for enamel demineralization to occur. Of the 20 follow-up subjects, 12 (60%) exhibited worsening tooth wear. The mean values for daily carbohydrate, protein, and fat intake were not significantly different at baseline and at recall, and the proportional dietary intake was similar to recommended energy provision at 47%, 40%, and 13%, respectively.
CONCLUSIONS
The contribution by toothbrush abrasion to the overall wear in the eroded dentition of bulimics is not significant. Therefore, immediate post-vomiting oral hygiene practices can be recommended. The proportional nutritional intake values of carbohydrates, fats, and proteins in this group of bulimics are acceptable.
