Maxillar and mandibular incisors were studied in rats treated with cortisone. This hormone has pronounced effects on the normal development of these teeth. Histopathologic changes were observed in pulp, predentin, and dentin. They were characterized by disorganization and lowered differentiation of the odontoblasts, increased number of cells in the pulp, and excessive formation of a bone-like substance containing cellular and vascular inclusions. The changes have features in common with those observed in C- and A-avitaminosis experiments in various animals.
