Introduction:
Cemento-osseous dysplasias (CODs) for short, are a group of relatively benign, or harmless jaw conditions, where there’s fibrous connective tissue containing abnormal calcifications within the jaw bones, in place of normal bone.
Benign fibro-osseous lesion of bone, in which normal bone is replaced by fibrous tissue, followed by calcification with osseous and cementum-like tissue.
- M/C type of fibro-osseous lesion to affect jaw
- Commonly seen in African-American females.
Classification
According to location:
- Periapical COD (periapical region of anterior teeth) (M/C subtype)
- Focal COD (associated with a single tooth)
- Florid COD (FCOD) (lesions appear in > 1 quadrant)
Clinical features
Usually asymptomatic and occurs in the periapical area of teeth with vital pulps or in regions of extractions.
- Local jaw expansion and mild discomfort (⅓ cases)
Diagnosis
Radiography:
FCOD appears radiolucent in its early stages. As it matures, radiopacities appear within the lesion, causing them to show a mixed appearance of radiolucency and radiopacity.
