title: [Anatomical and radiographical studies of the bifid mandibular canal].
abstract: To review the recent progress about the anatomical and radiographical studies of bifid mandibular canal (BMC) in English literature recorded in PubMed from 2006 to 2015 to deepen our understanding of BMC. A BMC is an anatomical variation of the mandibular canal; its occurrence might be a result of the incomplete fusion of mandibular canal during prenatal development. The four types of BMC have been classified according to anatomical location and configuration. Characteristic radiographic features and identifying methods of BMC on panoramic radiography and cone beam computed tomography (CBCT) were described; the visibility of BMC on panoramic radiographs and CBCT images was compared. Clinical value of identifying the location as well as the configuration of BMC for surgical procedures that involve the mandible was discussed.
