Abstract
Our department had 56 cases of odontogenic tumors during a period of 14 years and 3 months (1981-95) . These cases were histopathologically diagnosed according to the revised (1992) WHO histological typing of odontogenic tumors and examined clinicostatistically.
1. The cases consisted of ameloblastoma (23 cases, 41.1%), odontoma (22 cases, 39.3%), benign cementoblastoma (3 cases, 5.4%), malignancy (2 cases, 3.6%), clear cell odontogenic carcinoma (1 case), and primary intraosseous carcinoma (1 case) .
2. The tumors were found in 29 males (51.8%) and 27 females (48.2%) . Occurrence of ameloblastoma was predominant in males.
3. The patients' ages at their first visits ranged from 6 to 83 years ; the mean age was 32.1 years. The highest incidence of ameloblastoma was recognized in the fifth decade. Most cases of odontoma were diagnosed within the first two decades of life.
4. The mandibular molar region was the most frequent site of ameloblastoma.
