Abstract
The anatomy of mandibular single-rooted teeth often presents bifurcated root canals, missing one of these leading to failure of endodontic treatment. As the mandibular incisors are smaller in dimensions, proper access cavity preparation is technical, the lingual canal is more difcult to nd because of the angulation. Thorough knowledge and skills are required to negotiate all of the canals for successful treatment and prognosis. Acase report is presented to illustrate non-surgical endodontic management of mandibular lateral incisors with two canals having a common exit. Summary: The mandibular incisors or single rooted teeth of mandible are often thought of having only one canal relating to the anatomy of root. But on the other hand, the morphology of root canal system of mandibular teeth presents multiple variations and multiple canals in single rooted teeth. This case is presented here with mandibular lateral incisor having two canals with common entrance and exit.
