  • Objectives: To evaluate type and prevalence of incidental findings from cone beam computed tomography (CBCT) of the maxillofacial region. Findings are divided into those that required 1) intervention/referral 2) monitoring and 3) no further evaluation. Methods: 300 consecutive CBCT scans conducted in the School of Dentistry Oral and Maxillofacial Radiology Clinic, from January 1 to August 31, 2008 were retrospectively reviewed. Findings were grouped into categories: airway, soft tissue calcifications, bone, TMJ, endodontic, dental developmental, and pathological. Results: 90.7% revealed a total of 881 incidental findings (3.2 findings/scan). The most prevalent was airway findings (35.0%), followed by soft tissue calcifications (20.0%), bone (17.5%), TMJ (15.4%), endodontic (11.3%), dental developmental (0.7%) and pathological (0.1%). 16.1% required intervention/referral, 15.6% required monitoring, and the remainder required neither. Conclusion: This study underscores the need to thoroughly search for clinically significant lesions within and beyond the region of interest for all CBCT volumes of data.
