Root canal treatment (RCT) deals with repairing and saving the tooth that is badly decayed or becomes infected. Endodontic means treating tooth from inside. Obturation is a process of complete filling and sealing of 3D root canal space with gutta percha as biocompatible sealing material against bacterial growth. The main cause of Endodontic treatment failure is the incomplete sealing of the root canal. The degree of endodontic success needs to be evaluated based on mechanical sealing of root canal cavity with gutta percha also there is a need to quantify measures for evaluating Root canal success. Current paper discusses the effect of mechanical factors on success in this treatment. © 2017 IEEE.
