Endodontic treatment of mandibular canine with two canals – A case report

Abstract

The mandibular canine is usually considered a single-rooted tooth with a single root canal. However, two canals and more rarely two roots may also occur. This paper reports the case of a patient with bilateral mandibular canines with two roots and two root canals. The initial periapical radiographs of the mandibular right and left canines for endodontic treatment revealed the presence of two root canals in each tooth. After coronal opening, the cervical third was prepared with a SX file of the ProTaper system and root canal length was confirmed using Root ZX mini electronic apex locator. Root canal preparation was completed with the series of ProTaper instruments and the root canal was filled with gutta-percha and AH plus sealer. The final radiographs showed two well-obturated canals ending at the electronically located apices. Clinicians should always consider the presence of anatomical variations in the teeth during endodontic treatments. Despite the low prevalence, variations may occur in the number of roots and root canals of mandibular canines, as demonstrated in this case report.
