Abstract
Abstract. Historically, erythrodontia has been associated with congenital porphyria although it has been reported only inconsistently. The disease and its dental pigmentation have been reviewed briefly in this paper. In addition four teeth from porphyric patients and 18 teeth from cattle with porphyria were analyzed for porphyrin content. Fluorescence microscopy was employed to determine the pattern of porphyrin deposition. Porphyrins were found to be present in both enamel and dentin, although the concentration varied considerably and was generally much higher in the dentin. The concentration of porphyrins in the teeth would appear lo be influenced by the severity and duration of the disease. The presence of porphyrins in bands of higher and lower concentration corresponding in contour to the incremental growth lines of the teeth probably reflected exacerbation – remission cycles of the disease during formation of the teeth.
