Cemento-osseous dysplasia (COD) is a benign condition of the jaws that may arise from the fibroblasts of the periodontal ligaments. It is most common in African-American females. The three types are periapical cemental dysplasia ( common in those of African descent), focal cemento-osseous. The distinguishing histopathologic features of focal cemento-osseous dysplasia ( FCOD) (including lesions occurring in both anterior and posterior jaws) and.

This is because of the deposition of cementum-like droplets in the fibrous tissue. Semin Diagn Pathol ; Unfortunately, none of these authors 2,22 reported the frequencies or proportions of individual radiographic features.

Cemento-ossifying fibroma is an encapsulated benign neoplasm cemento-ksseous up of highly cellular fibrous connective tissue that contains varying amounts of osteoid, bone, cementum and cementum-like calcified tissue. J Oral Maxillofac Surg. This deposition may occur because of poor vascularity of the altered dysplastic tissue when there is communication with the oral cavity. The lesion caused perforation and expansion of alveolar bone.

The intermediate stage of FOD is most frequently confused with ossifying fibroma because of the presence of osteoblasts and osteoclasts near the bony trabeculae [ 28 ].

In addition, 15 The current study had several limitations. D Cross-sectional view of the lesion; radiolucent area around the sclerotic mass giving the appearance of encapsulated lesion.

A clinicopathologic study of cases. FCOD is seen predominantly in African-American black women, with a peak incidence in the fourth and fifth decades. Cemento-osseous dysplasias CODs are fibro-osseous lesions in which the normal bone architecture is replaced by fibroblasts and collagen fibres containing variable amounts of mineralised material. Focal sclerosing osteomyelitis is characterised by an asymptomatic, non-expansile periapical lesion associated with a tooth exhibiting deep caries.

Pathology of the maxilla and mandible Musculoskeletal disease stubs. Diffuse sclerosing osteomyelitis and florid osseous dysplasia. Vessels in FOD are dilated, irregular, and closely associated with the bony trabeculae, with an interrupted endothelium [ 8 ]. Additionally, lesions tend to be small and focal, averaging 1.

A non-expansile, mixed radiolucent-radiodense lesion in the posterior mandible, distal to tooth Periapical COD is bilateral and is located at the root apices of the mandibular anterior teeth; it shows a predisposition for middle-aged black women. The teeth that are related to the lesion are vital, and FCOD is generally ceemnto-osseous.
