Incidental bony pathology when reporting trauma orthopantomograms.
Radiologists frequently report orthopantomograms (OPTs) and other views of the mandible, most often in patients who have suffered facial trauma. These examinations may reveal incidental pathology. It is important that radiologists are aware of the radiological appearances and the clinical significance of these lesions. In this review we will present examples of the more common odontogenic lesions including: radicular cyst, odontogenic keratocyst, dentigerous cyst, ameloblastoma, and also examples of non-odontogenic pathology: bisphosphonate-related osteonecrosis of the jaw (BRONJ) and chronic osteomyelitis. Although some of the lesions will require computed tomography (CT) or magnetic resonance imaging (MRI) for further lesion characterization and evaluation of the surrounding tissues, we are going to focus on the plain film appearances. We will also briefly discuss the pathogenesis, epidemiology, and treatment of these lesions.
