Abstract: The aim of this study was to determine the relative frequency and clinicopathologic presentations of odontogenic tumors in an Iranian population. We reviewed the archives of 110000 files from 1997-2007 in the Department of Pathology of Shiraz Dental School and two main head and neck referral hospitals in Shiraz by using the criteria for histological classification of odontogenic tumors published by WHO in 2005. Information about clinical featuers (age, sex and location etc.) were obtained from the patients’ chart and analyzed by χ2-test. We found 118 cases of odontogenic tumors which were all benign. Keratocystic odontogenic tumor was the most frequent tumor (42.3%) followed in descending order by ameloblastoma (30.5%), odontoma (9.3%), calcifying epithelial odontogenic cyst (6.7%), myxoma and adenomatoid odontogenic tumor (2.5%). Odontogenic tumors are uncommon lesions in the Shirazian population. The overall male to female ratio was 0.9:1 and the mandible was obviously more affected than the maxilla (3.04:1).
