Endodontic treatment may sometimes fails because morphological features of the tooth adversely affect the treatment procedures. The knowledge of root canal system of different human teeth is a “road map” for the successful root canal treatment. Many investigators have reported the anatomical variations associated with mandibular canines. Mandibular canine usually contains one root with a single root canal. Two‑rooted mandibular canine is rare. Human mandibular canines do not present internal anatomy as simple as could be expected; there are such Canines with a single root and two canals, two roots or fused roots. This paper describes two cases of root canal therapy of permanent mandibular canine with two root canals and one apical foramen (Type II) in one root.
