Bifid mandibular canal - a case report.

One of the most common anatomical variations of the mandibular canal is the bifid mandibular canal (BMC), more frequently unilateral and rarely bilateral, often located at the level of the posterior mandible; according to literature, this anatomical variation presents several morphological types. The presence of the BMC must be considered prior to anesthesia and surgery performed on the ramus of the mandible (osteotomies) and on the posterior mandible (dentoalveolar surgery procedures). This study presents a clinical case of unilateral BMC on the left side, the buccolingual type, lingual variant, a rare anatomical variation illustrated radiographically in a 27-year-old male adult.
