Abstract
This study aims to analyze the frequency and distribution of odontogenic tumors in a Greek population and compare the findings with those reported in the recent literature. Records of the Department of Oral Medicine and Pathology, Dental School, University of Athens, with histologic diagnosis of odontogenic tumors (based on the World Health Organization 2005 classification) were reviewed retrospectively from January 1970 to December 2011. A total of 652 cases of odontogenic tumors were reported. Of these, 651 (99.8%) were benign and only 1 (0.2%) was malignant. Keratocystic odontogenic tumor was the most frequent lesion (52.7%), followed by odontoma (18.9%) and ameloblastoma (16.1%). The mean age of patients was 38.0 years with a wide range (2.5-92 years). Odontogenic tumors are rare lesions and appear to show a definite geographic variation. In Athens, Greece, they are presented mainly by the keratocystic odontogenic tumor, odontoma, and ameloblastoma.
