    Abstract:
    AIMS AND OBJECTIVES: To study the clinical, histological features of peripheral and central ossifying fibromas and also to compare between them. MATERIALS AND METHODS: The sample comprised a total 50 cases of ossifying fibromas [25 central ossifying fibromas (COF) and 25 peripheral ossifying fibromas (POF)] inclusive of cemento-ossifying fibromas. RESULTS: The mean age is 28.2 years in POF and 24.7 years in COF. The male: female ratio was 1:1.5 in POF and 1:1.8 in COF. The size of the lesions varied from 0.45 to 2.75 cm in cases of POF and in COF, it ranged from 1.25 to 13.5 cm. COF showed more duration (1-8 years) when compared with POF (1-3). Majority of cases of COF showed radiolucent, mixed radiolucent and radiopaque unilocular lesions. The predominant cell type in both POF and COF was a combination of both ovoid and spindle cells. Regarding vascularity it showed mild, moderate and intense vascularity. On comparison of all stromal changes between POF and COF showed no statistically significant difference. CONCLUSION: The clinical parameters and radiographic changes of POF and COF in our study were similar to the previous studies. Histopathological features like type of cells, cellularity and vascularity in POF and COF were similar to previous studies. However, when clinical and histopathological features were compared between POF and COF showed no statistical significance except for site of the lesion. These features signify the behavior of two lesions. Further research on larger sample might give more insights into these lesions.
