Oral alterations in patients diagnosed with eating disorders (ED) are reported in the literature, but few articles demonstrate these changes in a specific population. This study aims to summarize the findings of 26 patients with ED in a Brazilian dental clinic, through analyzing the body mass index and oral conditions (decayed, missing and filled teeth-DMFT, dental wear, salivary flux, xerostomia, oral hygiene-OHI-S, oral lesions, and the prevalence of candidiasis), in order to facilitate recognition and enable accurate diagnosis for the general dentist. Probably, the premature diagnosis of ED resulted in lower DMFT and oral lesions.
