Peripheral Ossifying Fibroma in Maxillary Bone

Abstract

characterized by replacement of normal bone tissue by fibrous connective tissues.1 They are classified into fibrous dysplasia, ossifying fibroma and osseous dysplasia.2 Peripheral ossifying fibroma is benign and it grows slowly.3-5 It occurs when pluripotent cells of periodontal ligament transform into osteoblasts, cementoblasts and fibroblasts.3,5-8 It occurs mostly in women and occurs at the age of 20-40.8-10 Peripheral ossifying fibromas are usually painless lesions smaller than 2 cm.1,3-7,9,11 They are most often located inside the bone. Approximately 60% of them occurs in the anterior part of the maxillary bone. Recurrence of the disease is common after surgical treatment.
