Endodontic management of Mandibular Premolar with Two Roots

Abstract Thorough knowledge about the anatomy and morphology of tooth root canal system is the key for successful outcome of endodontic treatment. False assumptions about the canal anatomy of teeth may lead to misdiagnosis, missed canals, improper debridement and breakage of instruments within the root canal during treatment and moreover the persistent pain to patient. Teeth often shows changes in their anatomy of the pulp chamber and root canal system which brings challenge to clinician. Mandibular first premolar shows very low incidence of variations in its root canal system. But for successful root canal treatment these variations had to be kept in mind and to take in consideration for proper cleaning and shaping.
