Abstract

Aim: With the development of surgical procedures, as the mandibular anterior dental implants and chin surgeries, there has been an increase in complications associated with anatomical elements in this anterior area. One of the most dangerous complications is related to bleeding caused by injured vessels associated with the lingual foramen and canal, which can cause a compression of the airway.
Methodology: Eighty-two CBCT scans for Egyptian individuals were collected from the data base available at the Department of Oral and Maxillofacial Radiology, Faculty of Dentistry, Cairo University. Scans were selected according to specific inclusion and exclusion criteria, they were interpreted by two oral radiologists and analyzed in the three planes axial, coronal and sagittal. The midline was drawn on the axial scan by a line passing through the convexity of the genial tubercle to the mental ridge. The procedure was then standardized by adjusting the slice thickness and the spacing between all cuts at 0.4mm. After determining the midline on the axial plane, from the sagittal plane five consecutive cuts were taken on each side of the midline, these cuts were used for the assessment of the prevalence and the number of lingual canals present.
