title: Central odontogenic fibroma.
abstract: Central odontogenic fibroma (COF), which has been categorized under the subheading of odontogenic tumors of ectomesenchyme, is such an uncommon neoplasm that much of its nature is left uncharted. COF is a rare tumor that accounts for 0.1% of all odontogenic tumors. Clinically, the lesion grows slowly and leads to cortical expansion. Radiologically, the lesion may be unilocular or multilocular. In some cases, it may be associated with root resorption or displacement. Histopathologically, the lesion is characterized by mature collagen fibers and numerous fibroblasts. A case of COF of the mandible in a male patient aged 49 years is described in this report. The patient showed no symptoms, no history of swelling discomfort or pain, and was unaware of the presence of the lesion. Orthopantomogram (OPG) showed generalized bone loss along with a unilocular radiolucent area, with a clear sclerotic lining and angular bone loss. Surgical enucleation of the lesion along with placement of osseo-graft, which is a bioresorbable demineralized bone matrix (DMBM), and platelet-rich fibrin was carried out in the defect site. Following surgery, patient was recalled for revaluation of the lesion; the surgical site showed good healing and an increase in bone height was seen.
