A case of an ovarian dermoid is reported which contained three erupted teeth and one tooth germ. In addition to the teeth the specimen contained bone, hyaline cartilage, nervous and brain tissue, cysts, pigment cells, fat tissue, and skin with hairs and sebaceous and sweat glands. The erupted teeth were held in place by a periodontal membrane of the type found in teeth without function. The pulp tissue presented a slight degree of atrophy. The unerupted tooth germ had normal-appearing ameloblasts, Hertwig's sheath, and epithelial rests of Malassez. In the dentin a 33 micra incremental rhythm was found. The topographical relationship between erupted and unerupted teeth closely resembles the usual arrangement of deciduous teeth and permanent successor teeth, and is additional evidence to the reports by Sannai, Kanamori, and Churchill that teeth belonging to two generations may occur in ovarian dermoids.
