Coeliac-type dental enamel defects in patients with dermatitis herpetiformis.

Abstract

The teeth of 30 adult patients with dermatitis herpetiformis and 66 sex- and age-matched healthy controls were examined for dental enamel defects. Sixteen of the patients (53%) with dermatitis herpetiformis, opposed to only one (2%) of the healthy controls (p less than 0.001), were found to have coeliactype permanent-tooth enamel defects. The grades of these defects were milder than those described for severe coeliac disease. There was no correlation between the degree of enamel defects and jejunal villous atrophy. The present finding of frequent coeliactype dental enamel defects in adults with dermatitis herpetiformis suggests that these patients were already suffering from subclinical gluteninduced enteropathy in early childhood, at the time when the crowns of permanent teeth develop.
