Study Notes

Ossifying Fibroma and Cemento-Osseous Dysplasia in Maxillofacial Region

Ossifying Fibromas primarily affect the dentate segment of the mandible and maxilla
They are slow-growing in adults but aggressive in younger age groups, causing displacement of teeth
Ossifying Fibromas demonstrate well-delineated or encapsulated cellular fibrous connective tissue with osseous products
They are more commonly seen in the mandible (77%), especially in the molar region
The peak age for Ossifying Fibromas is in the 3rd and 4th decades, with a strong female predominance (5:1)
Radiologically, they appear as well-demarcated, unilocular, and can show a mixed radiolucent/radiopaque appearance
Ossifying Fibromas can cause bowing of the mandible, thinning of the lower border, and resorption or divergence of roots
Surgical curettage is a preferred initial treatment option for Ossifying Fibromas, as they can be easily shelled out from the surrounding bone
The recurrence rate of Ossifying Fibromas is variable and unpredictable
Cemento-Osseous Dysplasia is a non-neoplastic fibro-osseous lesion occurring in tooth-bearing areas of the jaws
Cemento-Osseous Dysplasia shares clinical and histological similarities with other fibro-osseous lesions like fibrous dysplasia and ossifying fibroma
Lesions exhibiting aggressive behavior and recurrence may require resection, and treatment depends on the location, age of the patient, and aggressiveness of the lesion
