Cemento-osseous dysplasia-like lesions associated with impacted tooth: A case series with review of the literature

Cemento-osseous dysplasia (COD) is a common fibro-osseous lesion, seen in tooth-bearing areas of the jaws and mostly is located in the periapical region. Clinically, COD is asymptomatic, unless it is secondarily inflamed. COD associated with impacted tooth has not been well documented in the literature. We report a series of 6 cases related to 5 patients who presented COD in association with the impacted third molars. All the patients except one were female, aged 39–72. Pain or swelling was present in two cases. Radiographically, all the lesions were mixed radiolucent/radiopaque or radiopaque, localized at the periapical region, except one in which the impacted tooth was horizontally positioned and the lesion was found to be pericoronal. Diagnosis of COD was confirmed, histopathologically in 3 out of 6 cases. No post-operative complication or change was noted in the cases. COD in association with an impacted tooth warrants consideration in clinico-radiographic differential diagnosis by dentists for appropriate treatment/management.
