A 22 year old male patient reported with history of trauma and discolored maxillary central incisor which was non-vital upon pulp testing. Root canal treatment was planned. Access opening was performed with standard access cavity preparation set. No canal was located upon access opening initially it seemed to be calcified canal. Further access was made by the munce discovery bur #1 and #2 for locating the canal. Ultrasonic tips were used to locate canal orifice. Then finally access was gained to the canal. The main canal was located and the access was further modified to locate the additional canal. Using a surgical operating microscop under ×3 magnifications the additional canal was located lingual to the main canal and the working length was determined. Chemo-mechanical preparation was done by the Crown-Down technique with K-File system. Tooth was obturated by using lateral condensation technique with AH plus sealer. A postoperative spiral CT examination was carried out to study and confirm the unusual root canal morphology of the tooth. It was concluded that tooth had two root canals with vertucci type V pattern.
