One hundred and thirty-five cases of odontogenic tumors experienced from October 1981 to June 2002 at the Department of Oral and Maxillof acial Surgery, Nara Medical University, were clinico-statistically studied according to the WHO classification of 1992. The tumors were classified into 56 ameloblastomas, 41 compound odontomas, 18 complex odontomas, 17 other benign tumors, and 3 malignant tumors. The age of patients at the first visit ranged from 5 to 77 years, with the mean age of 29.8 years. The tumors were found in 71 males and 64 females, with the male to female ratio of 1.1: 1. There were 45 cases in the maxilla and 90 cases in the mandible. The frequent sites of the ameloblastomas, compound odontomas and complex odontomas were the molar region of the mandible, the anterior region of the maxilla, and the molar region of the mandible, respectively. Most of the chief complaints were the evaluation of lesion, except for ameloblastoma, in which the chief complaint was swelling. Radiographic patterns of ameloblastoma were multilocular in 22 cases, unilocular in 14 cases, and honeycombed in 3 cases. Thirty-nine cases were associated with impacted teeth. The absorption of root of the adjacent teeth was found in 24 cases of ameloblastomas. The treatments were enucleation in 90 cases, marsupialization in 16 cases, segmental resection of mandible in 12 cases, marginal resection of mandible in 3 cases, and partial resection of maxilla in 3 cases. Recurrence was found in 3 ameloblastomas of primary cases, and in 3 ameloblastomas, 1 odontogenic mxyoma and 1 malignant ameloblastoma of secondary cases.
