Research output: Contribution to journalArticlepeer-review


Mandibular premolars usually have a single root and canal. Complex root canal system with atypical variations is a common finding among them. Failure to identify such a one can affect the prognosis of endodontic treatment. Apart from knowledge and sophisticated instruments, a good clinical expertise is required in identifying, tracing and treating such a root canal system. This case report is on the retreatment of a left mandibular second premolar (44) having a Vertucci's Type III canal configuration. Inability to identify this canal configuration led to a missed canal, faulty obturation and post treatment apical periodontitis.
