The visibility of the mandibular canal varies according to individuals and its path in the same individual. The purpose of this study was to assess the visibility of the mandibular canal path on digital panoramic X-rays. Materials and methods: This is a cross-sectional study of panoramic radiographs of Senegalese subjects. The path of the mandibular canal was subdivided into three areas: posterior, middle, and anterior. Results: Of the 215 digital panoramas analysed, the mandibular canal (CM) was invisible in the anterior area in 96% (n=413). In the middle portion of the mandible, in 65.3% (n=281) of cases the CM was less visible 62.3% (n=134). It was more visible in the posterior area. Conclusion: The mandibular canal was more easily identified in the posterior areas, and visibility gradually diminished towards the mental foramen.
