Abstract

Trifid mandibular canal (TMC) is one of the anatomical variation of mandibular canal with clinical importance. An extra mandibular canal may explain inadequate anesthesis and be damaged causing paresthesia or bleeding during mandibular surgery. CBCT with high-level spatial resolution is an useful tool for the detection of mandibular canal and its variation. The aim of this report is to present a case of trifid mandibular canal with CBCT images and to give information on this anatomical variation of mandibular canal.
