[Radiolucent and opaque lesions on a panoramic radiograph; a cyst or not?]

In the context of pain diagnostics, several lesions, partially radiolucent and partially opaque, were identified by chance in the mandible and maxilla. On the basis of the characteristic x-ray image, it was assumed to be cemento-osseous dysplasia. At an early stage, this cannot easily be distinguished from apical periodontitis. An incorrect diagnosis could lead to needless endodontic treatment.
