Cemento-ossifying fibroma is classified as an osteogenic tumor, defined as a well -differentiated tumor, occasionally encapsulated, comprising fibrous tissue. Abstract. Introduction: Cemento-ossifying fibroma is a benign fibro-osseous maxillary tumor belonging to the same category as fibrous dysplasia and. Background: Cemento-Ossifying Fibroma (COF) is considered by most as relatively rare, benign, non-odontogenic neoplasm of the jaw bones and other.

A more aggressive form of COF which occurs in younger individuals has been designated as Juvenile cemento-ossifying fibroma [ 10 ]. Unable to process the form.

Implant prosthetic rehabilitation with a free fibula flap and interpositional bone grafting after a mandibulectomy: Due to the good delimitation of the tumor, surgical removal and curettage is also a treatment of choice. X-ray diffraction analysis indicated that the mineral phase of both central and peripheral tissues consists of apatite crystals and that the crystallinity of the apatites might improve progressively with the development of the lesion, possibly to the same degree as that of bone apatite [ ossitying ].

However, Eversole and his co-workers in a study of 64 cases of cemento-ossifying fibroma reported a recurrence rate of as high as 28 per cent following surgical curettage of these lesions. Occasionally bleeding occurred when he brushed his teeth. Cemento-ossifying fibroma COF are rare, benign neoplasms that usually arise from the mandible or maxilla.

Cemento-ossifying fibroma of the mandible

There is a female prominence in these lesions, with a ratio ranging from 2: Text book of Oral medicine. Clinical differential diagnosis of radicular cyst ameloblastoma, odontogenic keratocyst, and odontogenic myxoma were considered. Thank you for updating your details. The size of the lesion was and the shape was ovoid. Panoramic radiograph shows a well-defined mixed radiolucent and radiopaque lesion on left side of mandible extending from distal root of 34 to mesial root of 37 with radiolucent scalloped border without any cortication is seen.


Ossifying fibromas elaborate bone, cementum and spheroidal calcifications, which has given rise to various terms for these benign fibroosseous neoplasms.

Cemento-Ossifying Fibroma- A Case Report

The extent to which the tumor spreads, guides surgical therapy. Patient in the case report showing swelling in the region of the lower left mandible. Synonyms or Alternate Spellings: On intraoral examination, a deep occlusal wear facet is seen in relation to 36 which was non tender on percussion Figure 2.

A case report of cemento-ossifying fibroma.

Based on radiological and histological findings, case was diagnosed as central cemento-ossifying fibroma. Despite a preponderance of the literature supporting differentiation, some authors continue to argue that the POF or peripheral cemento-ossifying fibroma is the peripheral counterpart of the central cemento-ossifying fibroma [ 21 ]. A slowly growing pink soft-tissue nodule in the anterior maxilla of an adolescent should raise odsifying of a POF. Indian J Dent Res ; De Vi Cente Rodriguez, S.

There is confusion in the literature about the nomenclature to use when describing these lesions.

Eversole and Rovin [ 17 ] stated the similar sex and site predilection of pyogenic granuloma. J Oral Pathol Med ; Pre-treatment orthopantomograph and 3D CT showing a large, mixed radiolucent-radiopaque lesion over left body and ramus of mandible Click here to view.

Clinically, these tumours manifest as a slow-growing intra-bony asymptomatic mass, over a period of time lesion may become large enough to cause facial asymmetry. View at Google Scholar J. Pain aggravates on chewing food, on taking any hot and cold fluids and relieves on its own after sometime. They vary in radiopacity depending on the amount of cementum and bone that have been deposited.


Fibfoma multilocular lesions were more prominent in the mandibular posterior regions and in patients younger than years. Received Jul 14; Accepted Nov Peripheral cemento-ossifying fibroma of maxilla. The aetiology for such type of cases may be because of history of trauma [ 12 ] as it acts a possible triggering factor, postulating the lesion to be a connective tissue reaction rather than a genuine neoplasm [ 13 ].

Benign fibro-osseous jaw lesions of periodontal membrane origin: An analysis of cases. Case Report A 35 ossitying old female patient reported with a complaint of swelling on the lower left jaw since past 2 months [ Figure 1 ].

Enucleated lesion of the patient mentioned in this case report. Fibro-osseous lesions of the jaws. It is a benign growth, considered to originate from the periodontal ligament and presents as a slow-growing lesion, but may cause deformity if left untreated.

The bone-like component is predominant reminiscent of woven bone and is found in more ‘mature’ lesions 1. The lesion was well demarcated and pedunculated measuring approximately Figure 3. While one half of all cases are asymptomatic, the growth of the tumor over time may lead to facial asymmetry; the lesion causing cortical expansion.
