“…The assessment of the retromolar canal and the dental canal is important, for example, during the bone harvesting procedure, when precisely the retromolar region is used as a donor site. In addition, the retromolar canal is close to the third molar, which exposes it to the risk of damage during surgery [ 10 ]. However, there is disagreement in the literature on the use of the CBCT in the preoperatory stages in cases of third molar extraction [ 24 ].…”

“…The clinical implications of the presence of a bifid canal include failure of anesthesia in the posterior area of the mandible, neurovascular damage of the retromolar canal, bleeding, changes in the sensitivity of the involved area, and a pathway for the spread of infectious or tumor processes [ 9 , 10 , 11 ]. These clinical implications have been valid reasons why authors have attempted to describe the presence of these canals over the years, using different classifications ( Figure 1 ) [ 12 , 13 , 14 ].…”

Prevalence and Characteristics of Accessory Mandibular Canals: A Cone-Beam Computed Tomography Study in a European Adult Population

The purpose of this observational study is to evaluate the prevalence and main characteristics of bifid canals within a European adult population, analyzing cone-beam-computed tomography (CBCT). The population study examined 300 subjects. The CBCTs were performed between 2012 and 2019, using PaX-Zenith3D with a standard protocol of acquisition. The parameters analyzed were the presence and lengths of the bifid mandibular canals. The sample included 49% male and 51% female participants. The mean age of the patients was 47.07 ± 17.7 years. Anatomical variants of the mandibular canal were identified in 28.8% of the sides and 50.3% of the patients. In 7.3% of the subjects, the anatomical variants were present bilaterally. The most frequently encountered bifid canal was Type 3 (40.5%), followed by the Type 1 canal (39.3%), the Type 2 canal (14.5%), and the Type 4 canal (5.9%), 40% on the right side and 60% on the left side. The average length of the bifid canals located on the right side of the mandible was 11.96 ± 5.57 mm, compared to 11.38 ± 4.89 mm for those measured on the left side. The bifid mandibular canal is a common anatomical variation of the mandibular canal. It is fundamental to performing an accurate preoperative evaluation using CBCT analysis to avoid and/or reduce intraoperative and postoperative complications.
