|Abstract:||Objective: To study of the incidence of ﬁ bro-osseous lesions (FOL) from the clinicopathological feature by retrospective study in Department of Oral & Maxillofacial Surgery, Mahidol University. Materials and methods: 45 cases of FOL from a total of 1,962 cases of Thai patients were diagnosed from Department of oral and maxillofacial surgery, Mahidol university, in 10 years during 2003 and 2012. The demographic data, clinical, radiographic and histopathologic features from each individual patient's histopathologic records were reviewed and analyzed. Result: The most common was 46.67% ossifying ﬁ broma (OF), 28.89%ﬁ brous dysplasia (FD), 24.44% osseous dysplasia (OD). The gender incidence of FOL were 88.89% of cases occurred in female. The mean age of OF, FD and OD was 36, 38 and 47 years respectively. The incidence of location of FOL were 61.90 %, 90.91% OD mostly affected in posterior mandible but 76.92% FD affected in maxilla. The clinical feature of painless swelling is most common in 57.14% OF and 69.23% FD respectively, but 53.64% OD asymptomatic. The incidence of radiological feature, 42.86% showed mixed to radiopacity with well-deﬁ ned margin was predominent in OF, and 38.46% showed ground-glass and radiopacity with ill-deﬁ ned margin was predominant in FD. The incidence of histopathologic feature 84.62% FD showed woven and/or lamella bone trabeculae in specimens, but 80.95% OF were found cementum-like material. The incidence showed osteoblastic rimming 14.29% OF and 15.38% FD respectively. Conclusion: The clinical and radiological features of FOL in this study were similar to the most previous study, but the histopathological feature was varied in each subtype of FOL.|
