Cemento-osseous dysplasia (COD) is a benign fibro-osseous lesion of bone characterized by the replacement of normal bone by fibrous tissue and subsequently followed by its calcification with osseous and cementum-like material. It arises from the fibroblasts of the periodontal ligaments.
It is mostly asymptomatic in nature and requires no treatment. When secondarily infected, it becomes symptomatic and intervention is required.

As per WHO, there are three clinical presentation of cemento-osseous dysplasia.
- Periapical
- Focal
- Florid
Periapical cemento-osseous dysplasia
These occur in the anterior mandible and involve only a few adjacent teeth.
Focal cemento-osseous dysplasia.
involve few teeth in posterior mandible
Florid cemento-osseous dysplasia or Familial gigantiform cementoma
It is a more extensive form. it occurs bilaterally in mandible or in all jaw quadrants.
