The
mandibular canal (MC) is a bilateral intraosseous structure that contains the
inferior alveolar neurovascular bundle and plays a critical role in dental and maxillofacial
procedures. Although typically described as a single canal, several anatomical
variations may be observed, including bifid and trifid canals, the retromolar
canal, mandibular incisive canal, accessory mental foramen, anterior loop, and
lingual foramina. These variations arise mainly from embryological
developmental patterns and may significantly influence surgical and anesthetic
interventions. Failure to recognize such variations can result in neurovascular
injury, hemorrhage, neurosensory disturbances, or inadequate inferior alveolar
nerve block anesthesia. With the increasing use of cone-beam computed
tomography (CBCT), detection of these variations has improved substantially, as
CBCT provides high-resolution three-dimensional imaging and accurate
visualization of canal morphology and branching configurations. Therefore,
careful preoperative assessment of the MC and its anatomical variations is
essential for procedures such as implant placement, third molar extraction, and
orthognathic surgery. Systematic identification and appropriate radiological
evaluation help minimize iatrogenic complications, enhance treatment planning,
and improve overall patient safety and clinical outcomes in contemporary dental
practice.
