Abstract：A bifid mandibular canal (BMC) is a common variation of the mandibular canal,Because it is mainly located in the mandibular ramus,molar and retromolar regions,procedures such as extraction of an impacted third molar,dental implantation,bone transplantation,root canal treatment and sagittal split ramus osteotomy may cause complication,such as the injury of mandibular nerves.Because of cone-beam computed tomography (CBCT)'s high-resolution and accurate images,the anatomical structure of mandible can be shown clearly.And the prevalence of BMC according to CBCT is about 10.2％-65％[1-9],Moreover,the prevalence of BMC in CBCT is consistent of that in gross anatomical sections.Therefore,CBCT is valuable for evaluating position and direction of the BMC.This paper reviews the causes,classification,detection methods of BMC and the clinical significance.
