A case of florid cemento-osseous dysplasia occurring in the mandibular ramus

We report a case of florid cemento-osseous dysplasia (FCOD) occurring in the mandibular ramus. The patient was a 21-year-old woman who had had discomfort in the right mandibular gingiva. Since a panoramic radiograph by her dental practitioner showed a radiopacity in the right side of the mandible, she was referred to our department. A radiographic examination revealed a massive radiopaque lesion, measuring approximately 3×3cm, involving the entire mandibular ramus. The lesion was removed under general anesthesia. The lesion was diagnosed as a FCOD or other cemento-osseous dysplasia. There was no evidence of recurrence 18 months after the operation.
