Assesment of Anatomic Variations of the Mandibular Lingual Foramina in Egyptian Population Using Cone-Beam Computed Tomography (Cross Sectional Study)

Introduction: To avoid any major difficulties during surgery in the anterior mandibular area, it is crucial to identify the precise location and number of lingual foramina. Aim of the study: To assess the anatomic variations of mandibular lingual foramina in Egyptian population using cone beam computed tomography.Materials and methods: A total number of 365 CBCT scan have been assesed to detect the number of lingual foramina and their position in relation to the midline using Cranex 3D CBCT machine. Results: Out of 365 patients 233(63.8%) had one lingual foramin while 123 (34.2%) had 2 and only 7 (1.9%) had 3 foramina, number of females who had 2 foramen is more than that in males while number of males who had 3 foramen is more than females . Conclusion: At least one lingual foramina was found close to midline so care should be taken during any surgical procedures in this area.
