Abstract
Objective: To assess and compare the location and anatomical characterization of the mental and lingual foramina using CBCT and reformatted panorama. Materials and Methods: A retrospective cross-sectional study was conducted on CBCT images of the mandible of 108 patients that were obtained from the Radiology Unit database at the Faculty of Dentistry, Mansoura University. These scans were performed between 2017 and 2021. These CBCT scans were taken for radiological diagnostic purposes and/or surgical treatment. CBCT records were evaluated to detect the character of mental and lingual foramina using axial, cross-sectional images and reformatted panorama.Results: The round mental foramen was the most common shape. The most well-known horizontal position of the foramen was in line with the long axis of the 2nd premolar. Ten cases (10.2%) had accessory mental foramen which was detected on CBCT. Axial, cross-sectional, and panoramic reconstructions’ linear measures showed statistically significant results. A total of 463 lingual foramina were found. Individuals had between one and eight lingual foramina on their jaw. The sizes of lingual foramina were categorized as ≤1 mm and >1 mm. 72.7% were ≤1 mm and 27.3% were >1 mm. Only 35% of the lingual foramina seen were lateral lingual foramina. The majority of the lingual foramina (65%) were median lingual foramina. Conclusion: A detailed knowledge of the mental and lingual foramina anatomy and their variations is essential for dentists. CBCT (axial and cross-sectional cuts) is more effective than reformatted panorama for anatomic assessment of mental and lingual foramina.
