Ameloblastoma, jaw, odontogenic tumors


Purpose: The present study aimed to review a series of ameloblastoma cases by observing their clinicopathological and demographic characteristics. The data in this study were compared to previous studies. Methods: Seventy ameloblastoma cases were obtained from the archive of the Surgical Pathology Service of the Dental School of the Federal University of Bahia and were analyzed with regards to age, gender, clinical manifestation, radiographic aspect, anatomical distribution and histological subtype. These data were submitted to statistical analysis. Results: Of the 70 cases, 35 (50%) occurred in males and 35 (50%) in females. Young adults were most affected by tumors. Fifty-six (80%) of all tumor cases occurred in the jaw. The main histological subtype seen was unicystic ameloblastoma, which occurred in 35 cases. The majority of the tumors [n=57 (81.4%)] were treated with radical surgery. The differences in clinical aspects and anatomical distribution were shown to be statistically significant (P < 0.001). Conclusion: The clinical-epidemiological profile of the patients in the present study is similar to that in other populations, with unicystic ameloblastoma being the most common histological subtype seen.
