Maxillary central incisor with two roots: A case report

To achieve goals of endodontic therapy the clinician must have thorough knowledge about internal and external dental anatomy of the tooth and its variations in presentation. The internal anatomy of the maxillary central incisor is well known and usually presents with one root and one radicular canal system. This case report describes an endodontic treatment of a maxillary central incisor with two roots and two canal systems, demonstrated by radiography. Failure to recognize unusual root canal anatomy may lead to unsuccessful endodontic treatment.
