Endodontic management of mandibular canine with two canals
Abstract
Endodontic treatment may sometimes fail because morphological features of the tooth adversely affect the treatment procedures. Many investigators have reported the anatomical variations associated with mandibular canines. Mandibular canines are recognized as usually having one root and one root canal in most cases. This case report describes a clinical case of mandibular canine with two canals. 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. The existence of mandibular canines with more than one root canal is a fact that clinicians ought to keep in mind, in order to avoid failure during endodontic treatment. In spite of the low incidence of lower canines with one root and two canals, this possibility cannot be forgotten, inasmuch as the presence of a second canal in these teeth leads to difficulties in endodontic treatment. The precise knowledge of the dental endocanalicular system′s anatomy is essential in the success of the root canal therapy, because the failure to detect the accessories canals and the incomplete radicular obturation leads to the infection of the periapical space, which will ultimately result in the loss of the tooth.
