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 blacks), focal cemento-osseous dysplasia (Caucasians), and florid cemento-osseous dysplasia(blacks). Periapical occurs most commonly in the mandibular anterior teeth while focal appears predominantly in the mandibular posterior teeth and florid in both maxilla and mandible in multiple quadrants.
Treatment and diagnosis
There is no treatment necessary for any type of COD. Diagnosis is important so that the treating doctor does not confuse it for another periapical disease such as rarefying osteitis or condensing osteitis. Incorrect diagnosis could lead to unnecessary root canal treatments. It can be diagnosed by radiographic appearance. Confirming the tooth is vital, as is noting the demographic (African American females).
