A total of 38077 patients were considered. The overall prevalence of BMC was 18.0%. Studies that evaluated CBCT images reported higher prevalence of BMC compared to panoramic images (25.0% vs 3.0%). The prevalence of BMC was higher in men than women and slightly higher in right side than the left side of the jaw, but none of those differences were significant.</span></span></span><br> <span style="font-size:12pt"><span style="line-height:200%"><span new="" roman="" style="font-family:" times=""><b>Conclusion:</b> The results have shown a total prevalence of 18.0% for BMC. Detection power of CBCT images were higher than panoramics. There was no significant relation between prevalence of BMC with sex or side of the jaw.</span></span></span><br> &nbsp; Bifid mandibular canal, CBCT, Oral surgery, Panoramic, Systematic review 11 19 http://wjps.ir/browse.php?a_code=A-10-830-3&slc_lang=en&sid=1 Sahand Samieirad 100319475328460014539 100319475328460014539 Yes Department of Oral and Maxillofacial Surgery, Faculty of Dentistry, Mashhad University of Medical Sciences, Mashhad, Iran Mehdi Aryana 100319475328460014540 100319475328460014540 No Student Research Committee, Faculty of Dentistry, Mazandaran University of Medical Sciences, Sari, Iran Ali Mazandarani 100319475328460014541 100319475328460014541 No Student Research Committee, Faculty of Dentistry, Mazandaran University of Medical Sciences, Sari, Iran Iman Misagh Toupkanloo 100319475328460014542 100319475328460014542 No Student Research Committee, Faculty of Dentistry, Mazandaran University of Medical Sciences, Sari, Iran Milad Eidi 100319475328460014543 100319475328460014543 No 3.
