Background. e posterior region of the mandible is more often related to iatrogenic errors, but the interforaminal region is also not spared for neurovascular complications. is study aimed to use CBCT images to evaluate the prevalence of anterior nerve looping and its variations with age, gender, and dentition status. Methods. is retrospective study was carried out by studying 600 CBCTscans retrieved from archival records of a CBCTcenter in Lucknow. e scans were inspected by two trained investigators. e length of the anterior loop was measured using the measuring tool of Carestream 3D imaging software. Descriptive and analytical tests were performed. Results. e prevalence of the anterior loop of the inferior alveolar nerve was found to be 56%. e prevalence was found to be more on the right side (29.0%) compared to the left side (27.0%). e most common anterior looping of the inferior alveolar nerve was type 3 followed by type 1. Males were found to have significantly higher loops compared to females. e number of loops was found to decrease significantly with age. e mean length of the loop was found to vary from 1.14to1.61mm. Conclusion. e anterior looping of IAN is very much prevalent in the Lucknow population. e use of the CBCT technique and appropriate preplanning prior to surgery or implant placement should be performed to prevent nerve injury. 1.Introduction e fifth cranial nerve is known as the trigeminal nerve and has three branches which are the ophthalmic, maxillary, and mandibular. e third branch is called the mandibular nerve. It is the largest of the three branches and carries both afferent and efferent fibers. e mandibular nerve innervates the lower face and the mandible, including the teeth, the temporomandibular joint, and the mucous membrane of the mouth and the anterior two-thirds of the tongue, the mastication muscles, and some smaller muscles [1–3]. e inferior alveolar nerve is a mandibular nerve branch. e inferior alveolar nerve may extend beyond the mental foramen in an anterior and inferior direction, curving back to the foramen and forming a loop, which has been termed the anterior loop of the inferior alveolar nerve, of the mental nerve, or the mandibular canal [4–6]. e prevalence of the inferior alveolar nerve anterior loop has been found to be highly variable ranging from 22% to 94% [7, 8]. In addition, the length of the inferior alveolar nerve anterior loop has shown variations up to a maximum of 11 mm [9].
