title: Treatment of a mandibular canine abutment with two canals.
abstract: Human mandibular canines do not present an 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. The long-term success of the prosthodontic treatment depends directly on the quality of the endodontic treatment realized on the abutment teeth. The mandibular canine is very important as abutment for any type of prosthetic restoration. This article presents a clinical case of a canine tooth which displays a radicular morphology with two canals, which leads us to conclude that such anatomical variations on human teeth can also occur in our country as much as described in the international literature and cannot be overlooked when treating the teeth.
