Aim: Oral and maxillofacial surgeons (OMFSs) request cone-beam computed tomography (CBCT) examinations more than any other dental specialty. The aim of the current study was to determine the frequency and type of incidental findings (IFs) from CBCT examinations specifically requested by OMFSs. Materials and methods: The database of a university-based CBCT service was reviewed for examinations requested by an OMFS over a 1-year period. The indications for the CBCT request ranged from implant and impaction to trauma-related causes. A board-certified oral and maxillofacial radiologist (OMFR) reviewed the CBCT images and the collected data were analyzed for descriptive results. Results: The frequency of IFs was 78%. The greatest number of IFs was found in the paranasal region followed by the cervical vertebrae and the nasopharyngeal area. Most IFs were insignificant but nearly half the cases (48%) required a follow-up or referral appointment. Conclusion: IFs from CBCT examinations requested by OMFSs are common and a substantial number required follow-up or referral. Clinical significance: The results of the current study highlight the importance of examining the entire volume of CBCT examinations and reporting any and all IFs. This, in turn, requires adequate knowledge and training in CBCT image interpretation or, alternatively, effective collaboration with oral and maxillofacial radiologists.
