Objective: Studies on odontogenic tumors published from many parts of the world show a distinct geographic variation; however, there is little information available in the English-language literature on the relative frequency of odontogenic tumors in India. This retrospective study was designed to determine the relative frequency of odontogenic tumors in an Indian population and compare them with various reports from other parts of the world. The controversy still exists regarding the nature of odontogenic keratocyst or tumor, so it has not been included in this study. Results: A total of 60 cases of odontogenic tumors were reported in this period. The most frequent histological type was ameloblastoma (66.67%), followed by odontome (20%), adenomatoid odontogenic tumor (10%). In general, the odontogenic tumors showed a predilection for the mandible and the posterior regions of the jaws. Ameloblastomas occurred with a marked predilection for the mandible, while adenomatoid odontogenic tumor showed predilection for the maxilla, anterior regions of the jaws, and young females. Conclusion: Odontogenic tumors show a definite geographic variation. In our study, ameloblastomas were the most frequent odontogenic tumors, with distinct anatomic predilections.

Ameloblastoma, a benign epithelial odontogenic tumor, is locally aggressive. This tumor comprises about 1% of tumors and cysts arising in the jaws. It appears most commonly in the third to fifth decades and with equal frequency between sexes. Ameloblastoma prevalently occurs in the mandibular molar and the ramus areas. Recurrence frequently appears after inadequate treatment. They are usually benign in growth pattern but frequently invade locally and occasionally metastasize. In the present study, a case of unusually large plexiform ameloblastoma was presented with its clinical, radiological, histological features and treatment modalities, and this is the addition of one more case in the literature.
