Root canal therapy is a procedure in which inflamed pulp tissue and microorganisms are removed from root canals and pulp chamber, in order to eradicate infection and symptoms. Irrigation is a crucial step of an endodontic therapy and different methods and protocols are used to enhance the efficacy of irrigation. Ultrasonic activation of root canal irrigation agent is one of the effective methods that enhance the outcomes and success rate of endo therapies. It removes the smear layer, bacterial biofilms and debris by acoustic streaming and agitating the irrigant inside root canals. Similarly, a conventional method of agitation (manual dynamic agitation) also play an important role in endodontic therapy, particularly by improving the delivery of irrigation agent to the apex of a root canal. The later method involves agitation of irrigant with master gutta percha cone with continuous to and fro strokes manually.~In this study, the efficacy of both the different irrigation protocols will be compared and assessed based on post-operative pain, measured by Visual Analog Scale (VAS).
The study analyzes the difference in post operative pain after root canal therapy, after using different activation protocols and devices. The subjects are divided into 2 groups and a different activation protocol is used in each group. In one group, final activation of irrigating agent during root canal therapy is done with an ultrasonic activation device, and in the other group, manual dynamic agitation is done using master gutta percha cone. The Post operative pain is then compared at 6, 12, 24, 48, and 72 hour intervals
