Introduction: Oral surgical procedures involve the risk of injuring the mandibular alveolar, buccal, and lingual nerve with consequent transient or permanent paresthesia. The lack of knowledge concerning the anatomical variations of the mandibular canal had proven to increase the incidence of surgical complications. The purpose of the study was to evaluate the incidence and configuration of the bifid mandibular canal (BMC) based on orthopantomogram (OPG) images. Materials and methods: The sample of the research article consists of panoramic radiographs of 500 patients, of which 270 were men (54%) and 230 were women (46%). The normal anatomy of the mandibular canal and its variations were recorded according to the BMC classification given by Freitas et al. Results: Fifty-three BMCs were observed and their prevalence rate was 10.6%. The BMC was most predominant in men (56.6%) than in women (43.4%). The most predominant classification was class B (62.3%), followed by class C (24.5%), class D (11.3%), and class A (1.9%), mostly on the left side (51.0%). Conclusion: Based on the results obtained in the study, the prevalence rate was 10.6%. It was most predominant in men, unilaterally, on the left side and the most predominant classification was class B. It is concluded that a panoramic radiograph can also be used as a reliable tool in the identification of mandibular canal anatomy and its variations since it also provides accuracy as that of cone-beam computed tomography (CBCT). A thorough radiological evaluation is very important prior to surgical approaches in the mandible in order to prevent and avoid potential complications.
