- Abstract: Objective To investigate the types and incidence of bifid mandibular canal using cone beam computed tomography(CBCT)technology so as to enhance our understanding of these anatomical features and help reduce complications caused by trauma to the neurovascular bundle within them.Methods CBCT data of 803 patients from College of Stomatology,Xi'an Jiaotong University,were collected,and the types and incidence of bifid mandibular canal were statistically analyzed according to the Naitoh classification method.Results The incidence of bifid mandibular canal was 54.05％,with the occurrence rates for the retromolar canal and forward canal being 26.40％ and 32.75％,respectively.Conclusion To ensure the safety of treatments,it is recommended that oral clinical practitioners use CBCT to obtain three-dimensional images for precise assessment of bifid mandibular canal,thereby avoiding potential complications during the perioperative period.
