Abstract: Cemento-osseous dysplasia (COD) is a condition that, radiologically, can appear as a radiolucency, a radio-opacity, or a combination of the two. It is important for GDPs to recognize COD, as apical radiolucency can lead to unnecessary endodontic treatment. COD is a self-limiting condition and does not require treatment. Our case report is based on a 47-year-old male patient showing all the stages of COD.

Clinical relevance: It is important to recognize this self-limiting condition to avoid unnecessary treatment and it can be monitored radiographically without treatment.
