| Abstract | ||
| Background: mandibular canal course variations are found very rarely, nevertheless, their recognition may play a very important role prior to any surgical procedure involving the lower jaw. This study aimed to identify the variations in the different parts of the radiographic course of mandibular canal using digital panoramic imaging. Materials and Methods: The courses of the mandibular canal in 319 panoramic images of Iraqi subjects were evaluated carefully and any rare radiographic finding was recorded when identified. Results: A total of (5.95 % of the radiographic images examined in the present study demonstrated mandibular canal variations. The most common variation observed in the present study was bifid mandibular canal (1.88 %), followed by indistinct mental foramen (1.57%), then indistinct mandibular canal walls (1.25%) and indistinct mandibular foramen (1.25%). Conclusion: The course and configuration of the mandibular canal should be carefully observed in different locations because it posses many variations. Recognition of these variations is important in preventing the intra and post operative complications in certain dental procedures | ||
