Cemento-osseous Dysplasia Mimicking Periapical Cyst After the Orthodontic Treatment of the Mandible.

Cemento-osseous dysplasia (COD) is a non-neoplastic condition, characterized by the replacement of normal cancellous bone with fibrous tissues containing woven bone and cementum in the tooth-bearing areas. This report presents the case of a 21-year-old male who developed COD following orthodontic treatment. A panoramic radiograph showed a periapical radiolucent lesion in the right mandibular canine area.
