Central ossifying fibroma a tumor accepted by most investigators as being odontogenic in origin. These are neoplasms consisting of fibrous tissue containing varying amount of mineralized materials. In this presentation, we have described 2 case series, 1.A male aged 57 year with clinical findings of pulsatile socket & expansion of cortical bone with mandibular left side. 2. A female aged 43 year asymptomatic patient who presented an impacted 38, 48 and accidently we have found radiographic changes on OPG. We have done CBCT (3D Carestream) scan and radiographically diagnosis was confirmed. Radiographic imaging such as intraoral, panoramic & CBCT had been performed and radiographic diagnosis of Central ossifying fibroma of bone was made. CBCT extending its arm to explore easier possibilities of diagnosis.

Introduction The ossifying fibroma of bone is a central neoplasm of bone. Central ossifying fibroma a tumor accepted by most investigators as being odontogenic in origin. These are neoplasms consisting of fibrous tissue containing varying amount of mineralized materials. (1,2) The central ossifying fibroma is a relatively rare lesion which is commonly found in 3 rd to 4 th decade of life and in females than in males, and has a predilection for mandible than maxilla. (3) Radiographically, it is mostly a mixed radiolucent radiopaque. The density of radiopacity depends on the amount and form of calcified material. Lamina dura of involved teeth usually in missing, resoption of teeth may occur. The article reports 2 cases of ossifying fibroma of mandible with a brief discussion on its literature. II. Case Report 1: A male age 57 year reported to outpatient department of a Dental College with a history of non-healing wound in lower right back region of jaw since a month, which was result of extraction of tooth a month ago(figure1). The past medical and dental histories were non-contributory. Also the family history was not contributory. Clinical examination revealed a pulsatile socket measuring approximately 1x0.5cm in size in the 44 region of the jaw (figure.2). Buccal expansion was noted in relation to 42 to 45 region of the jaw. There was mobility with 45 and displacement of 43 noted (figure 3). A clinical diagnosis of non-healing socket with 44 was made. In radiographic evaluation, intraoral periapical radiograph was taken which shown evidence of radiopaque fleck suggestive of calcification (figure 4). Mandibular occlusal cross-sectional view showed evidence of bucco-lingual expansion of cortex at the level of 42 to 47 region (figure 5).
