Abstract
OBJECTIVE : This institutional study was designed to determine the relative frequency of odontogenic tumors and to provide the information with reference to age, sex, anatomic location, and also to compare the data with the previous reports from other studies. MATERIAL AND METHODS : A total of 489 cases of odontogenic tumors registered over a period of 38 years (February 1970 - March 2008) in the Department of Oral and Maxillofacial Pathology of Tamil Nadu Government Dental College and Hospital, Chennai, India were retrieved from the files of histopathology registers and were retrospectively analyzed. RESULTS : Odontogenic tumors in the present study constituted 4.13% of all the 11843 registered biopsies. The mandible was the most commonly affected anatomic location with 362 cases (74.02%). Ameloblastoma with a predilection for posterior mandible was the most frequent odontogenic tumor (67.68%), followed by adenomatoid odontogenic tumor (9%), odontoma (7.77%) and calcifying odontogenic cyst (5.52%). The patients were affected over a wide age range of 5-75 years with a mean age of 32.64 years and peak occurrence in 2nd and 3rd decades of life. Among the 489 cases only 15 cases (3.07%) were malignant. CONCLUSION : The incidence of 4.13% of odontogenic tumors observed in this study is the largest series from this part of the world. Ameloblastoma formed the single most common tumor of all odontogenic tumors. This study observed both regional and geographic variations in the frequency and distribution of odontogenic tumors.
