Received 6 February 2004; revised 29 November 2004; accepted 2 December 2004

Objectives: The objective is to call attention to and to review the literature of the anatomical variation: bifid mandibular canal.

Methods: A review of the literature is summarized. Additionally, the clinical and radiographic findings of a patient who presented a unilateral bifid mandibular canal are recorded.

Results: Bifid mandibular canals can be detected on a panoramic radiograph. More precise information about the course of the canal can be revealed on cross sectional CT images perpendicular to the alveolar ridge.

Conclusions: Bifid mandibular canals are often unrecognized. The detection of these anatomical variations is important because of its clinical implications. Special attention has to be paid in surgical procedures involving the lower jaw.

Keywords: duplicated; bifurcation; mandibular canal
