In conclusion, we evaluated the visibility of the mandibular canal walls on limited volume CBCT images with a small voxel size. Evaluation was performed in the range of 30 mm in length just posterior to the mental foramen, which was divided into three equal areas (areas 1, 2, and 3, from anterior to posterior). The superior wall was significantly more poorly visualized than the inferior wall in all areas. Cases in which more than two thirds of the superior wall was identified on CBCT images in areas 1, 2, and 3 were 44, 62 and 66%, respectively.
