ABSTRACT
Background: Ameloblastoma is a locally invasive odontogenic tumour arising from the remnants of dental organ and dental lamina and is a highly destructive benign tumour of odontogenic origin. Nine percent of odontogenic tumours are ameloblastomas. . Methods: The histological variants of Ameloblastomas are manifold, follicular, plexiform and acanthomatous are the most common ones among them. Ameloblastomas are classified radiologicaly into unilocular, multilocular and peripheral types. The present study is a descriptive retrospective study conducted to evaluate the histopathological variants of ameloblastoma. Results: The histopathological reports of the patients were reviewed for a period of 10 years. 40 patients were included in the study. Prevalence rate of 7.4% was seen. Age range of the patients of ameloblastoma was from 20-60 years. The most common age groupwas in the 3rd decade of life with more male predilection. Conclusion: The most common variant of ameloblastoma was of follicular variety. The most common site of occurrence of follicular ameloblastoma was posterior mandible.
