Cemento-osseous dysplasia 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.
