Even though about 50 cases of this lesion have been reported in English journals, very few have been mentioned in Japanese journals. The purpose of this paper is to report a case of regional odontodysplasia in a 13-year-old girl and to review the literature written in Japanese. The results obtained were as follows : 1. Regional odontodysplasia occurs most frequetly in young persons under 15 years old. 2. Regional odontodysplasia occurs most frequently in the anterior part of the maxilla, and usually affects both dentitions. 3. Histological characteristics of the regional odontodysplasia produces malformations and hypocalcification of all the dental structures. 4. The etiology of this lesion is not completely known, but it is usually thought that it is due to a disorder of the dental lamina at an early stage.
