Abstract: Objective??The?purpose?of?this?study?is?to?analyze?the?incidence?and?the?type?of?the?bifid?mandibular?canal?(BMC)?by?using?cone?beam?computed?tomography?(CBCT)?images. Methods??A?total?of?216?patients?(104?female?and?112?male)?who?underwent?CBCT?were?included?in?this?study.?The?CBCT?images?were?evaluated?for?the?incidence?and?the?type?of?the?BMC.?Results??BMC?was?observed?in?39?(18.06%)?of?216?patients?and?50?(11.57%)?of?432?sides,?female?18?(17.31?%)?and?male?21?(18.75%).?BMC?were?classified?into?four?types:?type?Ⅰ?17?sides?(3.94%),?type?Ⅱ?11?sides?(2.55%),?type?Ⅲ?20?sides?(4.63%),?and?type?Ⅳ?2?sides?(0.46%).?Conclusion??BMC?is?detected?at?a?high?rate?by?using?CBCT.?When?doctors?perform?surgical?procedures?in?the?mandible,?they?should?pay?attention?to?the?anatomical?variations?of?BMC?of?the?mandibular?canals.
