Missed Canals: The Usual Suspect of Endodontic Failure

Anomalous root and root canal morphology has been found to be associated with any tooth with varying degree and incidence. Especially in case of mandibular anteriors, incidence of two root canals in have been reported to be as low as 0.1% to as high as 62.5%. Knowledge of the root canal anatomy is the basic pre requisite for successful completion and outcome of endodontic treatment. Missed canals harbor bacteria which lead to treatment failure. This paper reports the case of a patient with mandibular lateral incisor and canines with two roots and two root canals.
