Objective: Odontogenic tumors show a distinct geographic variation. In 2005 a new WHO classification was published which included odontogenic keratocyst as one of the odontogenic tumors, renaming it as a keratocystic odontogenic tumor. To our knowledge there are only few studies based on 2005 classification in Asian subcontinent. This study was done to determine the relative frequency of odontogenic tumors in Gujarat and compare it with reports from other parts of the world. Study Design: A retrospective study was designed. Necessary information was obtained from the records of the Oral Pathology Department, GDCH Ahmedabad. The histopathological diagnosis were re-evaluated according to the criteria of WHO histological classification 2005. Results: A total of 209 cases were reported in just a short span of 5-years. The most frequent histologic type was ameloblastoma 47.4%, followed by Keratocystic odontogenic tumor (KCOT) 23.4%. Odontomas which are the most frequent odontogenic tumor in European and American subcontinent, accounted only 5.3% in this study. Conclusion: In India ameloblastoma and KCOT are the most frequent odontogenic tumors, thus supporting the distinct geographic variation of these rare tumors.
