Oral profiles of bulimic women: Diagnosis and management. What is the evidence?

This article is a critical appraisal of the literature on the oral complications of bulimia. The MEDLINE database yielded a total of 82 English-language reports published between 1966 and 2002 that were pertinent to the topic of oral manifestations and treatment of bulimia. The literature is composed primarily of reviews, letters, case reports with or without restorative management, and descriptive studies of small sample sizes. At present, retrospective case-control studies are the only studies available with levels of evidence in the vicinity of 3 to 4. From these studies it is apparent that bulimic women present with a variety of oral and pharyngeal signs and symptoms, including dental caries and tooth erosion, dental pain, increased levels of cariogenic bacteria, orthodontic abnormalities, xerostomia (the subjective complaint of a dry-mouth) and decreased saliva secretion (the objective measure), decreased salivary pH, decreased periodontal disease, parotid enlargement, and swallowing impairments. Dental erosion is the major finding associated with bulimia. Case reports describe restoration of damaged surfaces with porcelain-laminated veneers, dentin-bonded crowns with minimal tooth preparation, composites, and complete-coverage restorations. However, what is really needed is identification of oral markers of bulimic behavior for early detection of bulimic patients by dentists and by physicians that can prevent the deleterious effects of frequent vomiting on the oral/dental tissues.
