Dental practitioners may encounter bifid mandibular canals upon radiographic assessment, and may not understand the true extent of this presentation. The presentation of a bifid mandibular canal poses difficulties when carrying out dental procedures, including administration of mandibular block anaesthesia, oral surgical procedures of the lower third molars, orthognathic surgery and implant placement. Therefore it is of paramount importance that general dental practitioners be aware of the radiographic appearance, as incorrect diagnosis of this rare presentation can lead to detrimental consequences. The purpose of the communication is to draw dental practitioner's attention to the variations of bifid mandibular canals and ensure practitioners interpret radiograph correctly to make an informed diagnosis and eliminate the risk of damage and discomfort in the event of surgical treatment being carried out. It is advised that dental practitioners refer for further imaging such as a cone beam scan for greater understanding of the anatomical variation.
