Abstract: Cone beam computed tomography (CBCT) is a popular and often indispensable imaging modality used for the dento-alveolar tissues and immediate surrounding structures. It can be used across several dental disciplines including endodontics, implant planning, oral surgery and orthodontics. Furthermore, it is also commonly used in the medical specialities of oral and maxillofacial surgery (OMFS) and ear, nose and throat (ENT) surgery. In many of the images taken, there will often be findings/presentations that may not be expected, or familiar, to the reporting clinician.

Clinical relevance: Many incidental findings are innocuous, yet their recognition and documentation are essential because some will warrant medical or surgical intervention.
