The observation of bifid mandibular canals using cone beam computed tomography

Objective To investigate the prevalence of bifid mandibular canals (BMC), and to measure their diame⁃ ter and angle. Methods CBCT images of 500 patients were used for this study. The incidence and types of bifid man⁃ dibular canals were recorded according to a modified classification of Naitoh: Ⅰ,...

description Objective To investigate the prevalence of bifid mandibular canals (BMC), and to measure their diame⁃ ter and angle. Methods CBCT images of 500 patients were used for this study. The incidence and types of bifid man⁃ dibular canals were recorded according to a modified classification of Naitoh: Ⅰ, retromolar canal; Ⅱ, dental canal; Ⅲ, forward canal; Ⅳ buccolingual canal. The diameter and angle between the accessory canal and the main mandibular ca⁃ nal were recorded. Results Bifid mandibular canals were found in 32.2% of the 1 000 hemi⁃ mandibles, with the inci⁃ dence rate of 52.17%, 36.02%, 6.21%, 5.59% in TypeⅠ, Ⅱ, Ⅲ, Ⅳ respectively. There are 90 cases of the mandibular branch with a diameter greater than or equal to the backbone 1/2, and 100 cases that are less than 1/2 of the backbone. The angle between the mandibular branch and the trunk Ⅰ, Ⅱ and Ⅲ were 50.21° ± 22.25°、28.81° ± 11.5° and 13.50° ± 2.39° respectively. Conclusion Bifid mandibular canals were observed at a relatively high incidence using CBCT, and the most common type was the retromolar canal. It is suggested CBCT should be taken before mandibular surgery to give an accurate evaluation of bifid mandibular canals.
