Abstract: Knowledge about the anatomy and morphology of the root canal system plays an important role in the prognosis of endodontic treatment and its success. Maxillary third molars with two distobuccal canals have been rarely reported. Herein, we report a third maxillary molar with two canals in the distobuccal root and describe its successful endodontic treatment. Our patient was a 67 year-old man referred to a private endodontic clinic complaining of pain in his maxillary right third molar tooth. With the diagnosis of irreversible pulpitis, the tooth underwent root canal therapy, during which, after thorough negotiation of orifices, a second distobuccal canal was found. Cleaning and shaping were carried out and root canals were filled. A follow up was scheduled to ensure a successful endodontic treatment. In this case, we did not use any adjunct diagnostic modality. We only found the additional canal by extending the access cavity and paying attention to landmarks by probing the fissures and grooves between the main orifices but it seems that use of new methods can enhance a successful treatment especially in the elderly patients.
