Cone beam CT findings of retromolar canals: Report of cases and literature review
A 30-year-old male visited the Yonsei University Dental Hospital with a chief complaint of inflammation in the right mandibular third molar area. Routine panoramic radiography and CBCT scans were performed for the extraction of the right third molar. It was observed that there was RMC branching from the mandibular canal that passed superiorly and in the reverse direction of the right retromolar area on sagittal images of CBCT (). Two radiolucent canals surrounded by cortical bone were found on cross-sectional images perpendicular to the alveolar ridge (). RMC was not detected on routine panoramic radiograph ().
