Recurrent symptomatic cemento-osseous dysplasia: A case report

  • 1Department of Oral and Maxillofacial Radiology, School of Dentistry, Chonbuk National University, Jeonju, Korea.


Cemento-osseous dysplasia (COD) is a benign fibro-osseous lesion of bone, in which normal bone is replaced by fibrous tissue, followed by calcification with osseous and cementum-like tissue. COD is classified into 3 categories according to its location: periapical, focal, and florid COD (FCOD). On 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. Because FCOD is usually asymptomatic and grows in a self-limited manner, it does not require treatment. Secondary infection is the most frequent cause of symptomatic cases. We report a case of FCOD with symptoms that appeared after a dental restoration procedure and persisted after repeated operations. The purpose of this report is to emphasize the importance of thorough radiological evaluations of patients with FCOD before treatment.
