Abstract :Objective: In this study, it was aimed to evaluate the frequency of all mandibular neurovascular anatomical variations in the mandible in the Turkish subpopulation with Cone beam computed tomography (CBCT). Methods: Sagittal, axial, coronal, serial cross-sectional and three-dimensional reformatted 410 CBCT images were investigated in accordance with age and gender. Median lingual foramen, lateral lingual foramen, mandibular incisive canal, anterior loop, accessory mental foramen, retromolar foramen, bifid mandibular canal, absence of mental foramen were evaluated in multiplanar sections. The obtained data were analysed with the IBM SPSS Statistics 25 package program. Results: Images of cases with a mean age of 44.25 ± 17.47 years, consisting of 233 (56.8%) men and 177 (43.2%) women, total 410 CBCT were included in the study. The most widespread anatomical variation in all cases was the median lingual foramen (44.7%), followed by the mandibular incisive canal (33.9%). No statistically important relationship was found between the examined parameters and sex (p>0.05) Conclusions: Although the interforaminal region is known as a safe region for surgery, the results of this study show that the presence of lingual foramens and mandibular incisive canal is not at a level that can be ignored.
