So, it is mandatory that the clinician should possess a thorough knowledge of not only the normal anatomy of the root canal system, but also aberrations. To minimize the risk of endodontic treatment failure, a precise knowledge of the root canal morphology is vital. This present research will thus guide the practioners as well as students to take this into account and thus be of help in treating their patients successfully.
