FIBRO-OSSEOUS LESIONS OF THE JAW

Fibro-osseous lesions are a benign group of lesions in which normal bone is replaced initially by fibrous connective tissue and over a period of time it is in turn replaced by osteoid and cementoid tissue. It can affect both long bones and craniofacial bones. Among these those affecting maxillofacial bones involve a diverse group of pathologic conditions like developmental lesions reactive or dysplastic diseases and neoplasms. Even though these diverse groups of lesions differs in respective aetiologies they have a similar histological appearance making clinical diagnosis difficult based on microscopic features alone.
