Clinicopathologic Study of Intra- Osseous Lesions of the Jaws in Southern Iranian Population

Statement of the Problem: It is necessary for surgeons and practitioners to know about relative incidence and clinicopathologic features of lesions for accurate diagnosis and approach of pathologic lesions. Data are limited about overall incidence of intra-osseous lesions of the jaws in Iranian patients. Purpose: This study evaluated the clinicopathologic features of intra- osseous lesions of the jaws in an Iranian population, in a 22-year period. Materials and Method: In this cross- sectional retrospective analytical study, 4500 specimens in a 22- year period were reviewed. Baseline data of all patients with intra- osseous lesions including type and location of lesions as well as patients’ age and gender, were collected and analyzed by SPSS software using descriptive analysis and Chi-square test. Results: There were 1121 (25%) intra-osseous lesion. Odontogenic cysts and benign non- odontogenic bone lesions were the most common categories, respectively. The mean age of the patients was 30.1±16, the total male to female ratio was 1.1:1, and the most prevalent location of lesions was posterior of mandible. Conclusion: The results showed baseline information of intra-osseous lesions that were essentially similar to other populations; however, there were a few geographical differences. Further comprehensive studies in other parts of country are required to make a more reliable source of reference for clinicians and surgeons for evaluating and managing their patients more properly.
