Endodontic treatment of a mandibular canine with two roots.

ABSTRACT

Lower canine is a tooth with a robust, long root and very good implantation, making it a valuable abutment tooth for any type of prosthetic treatment. In order to treat it conservatively and to prevent its loss from the dental arch it is necessary to accomplish a correct and complete endodontic treatment, which involves knowledge of all its morphological variation. The mandibular canine usually presents one root with a single large canal centrally located. The possible anatomical variations are the existence of a single root with two canals and of two different roots, each having a canal. The incidence of lower canines with two roots is usually low, as described in various studies, but their presence in everyday practice shows that the clinician must consider them if he wants to prevent dental endodontic treatment failure. This article presents a relatively rare case of a patient whose right mandibular canine has two roots and two canals. Although the frequency of mandibular canines with two roots is very low, we must not forget that we can deal with such cases, which can obviously occur even in patients in our country, as the ones described in foreign specialty literature.
