Mandibular canines usually have a single root canal, but they may also have two root canals and, more rarely, two roots. The aim of this paper is to present a case report of a mandibular canine with two roots. X-ray diagnosis allowed us to suspect the presence of a second root in mandibular canine because of the presence of dual periodontal ligament spaces and lamina dura in the lingual position. The periapical radiography of the mandibular right canine revealed the presence of a second root, located in a lingual position. The canals were instrumented using K-files with crown-down preparation under irrigation with 1% sodium hypochlorite. The two root canals were cleaned, shaped and obturated by the lateral condensation technique. The tooth was restored with glass ionomer cement and a follow-up radiographic examination showed a satisfactory resolution of the clinical case. The ability to identify possible anatomical variations, such as the presence of additional roots, significantly increases the success rate of endodontic treatment.
