Endodontic treatment of mandibular canine with two canals

Introduction. Success in endodontic treatment depends upon the clinician's knowledge and ability to recogni-ze and diagnose the presence of anatomical and morphological variations of the root and canal system. Man-dibular canines are usually recognized as having one root and one root canal. In spite of the low incidence of mandibular canines with one root and two canals, their appearance should not be neglected due to the fact that the presence of a second canal in these teeth leads to difficulties in endodontic treatment. The aim of this case report is to describe mandibular canine with two root canals.Case presentation. 45-year-old patient presented for medical care due to the pain in a lower right canine. Cli-nical and radiographic examination revealed composite filling and caries with periapical radiolucent area and sensitivity to percussion in the mandibular right canine. By careful evaluation of the diagnostic radiology, it was observed that the mandibular canine had two canals. The patient was diagnosed with acute apical periodon-titis and root canal therapy was given following the standard protocols.Conclusion. Although the prevalence of two canals in mandibular canine is low, the clinician should always be mindful of variations in the number of canals for appropriate therapeutic management.
