The Incidence of Ameloblastoma among Multilocular Radiolucent Lesions in Posterior Region of Mandible

Background: Ameloblastoma is a highly recurrence odontogenic tumor occurring in both jaws. This study aimed at investigating the demographic data, radiographic and histopathological features of ameloblastoma. Methods: Patients diagnosed with ameloblastoma between 2018 and 2020 were retrospectively analyzed. Demographic data, clinical signs, and symptoms, radiological and histopathological data records were collected. Results: 50 patients diagnosed with ameloblastoma, of which 25 patients were male, and 25 were female, The age range obtained was 12 to 76 years, with a mean age of 36 years. Most lesions were observed in the white race (56.3%), followed by the black race (43.7%). 48 cases (94.7%) were detected in the lower jaw and 2 (5,3%) cases in the upper jaw. The ratio of maxilla to mandible was 1:25. Multilocular imaging was presented in 28 cases (59.3%), monolocular in 20 cases (37.5%), and 2 of which were peripheral ameloblastoma (3.2%). The plexiform pathological pattern was the predominant type.
