Endodontic retreatment of a mandibular canine with two roots and two canals: a case report

Background: The knowledge of root canal anatomy is considered essential in the diagnoses and treatment of endodontic cases to assure successful outcomes. Although the mandibular canine is known to be a single- rooted tooth with a single canal, variations can be seen. However, the incidence of a mandibular canine having two roots and two canals is extremely rare. Case Presentation: This article reports a case of non-surgical retreatment of mandibular canine, with two roots and two canals, presented to the clinic with a periapical lesion. Chloroform and H-files were used to remove previous gutta percha, canals were shaped with a profile rotary system, and irrigated with 2.5% sodium hypochlorite. The canals were then obturated with gutta percha and AH Plus sealer. Conclusion: Clinicians must use all the available tools to help them detect anatomical variations to manage their cases successfully.
