Abstract

Background: Root canal treatment is the procedure in which infected pulp is removed to eliminate microbial invasion and to maintain tooth form and function. It includes access cavity preparation, working length determination, adequate cleaning and shaping and obturation of root canals.
Objective: To compare the success rate by assessing the level of postoperative pain following root canal instrumentation using a manual K-file against a Rotary One shape file.
Material & Methods: Using a random selection process, 112 patients were split into two groups. In group A patient, root canals will be prepared by K hand files and in group B patients, root canals will be prepared by rotary one shape file. Patients were recalled after 72 hours to evaluate postoperative pain and score was recorded according to verbal rating scale (VRS).
Results: Significant association was found regarding Success in both groups ((Group A (K hand files), Group B (Rotary One shape file)) with p-value = 0.036.
 
 Conclusion: Within the confines of this study, it is possible to draw the conclusion that the hand K-file was found to have a significantly higher success rate for postoperative pain intensity after root canal instrumentation when compared to the Rotary One shape file and significant association was found between hand K- file and Rotary One shape file in terms of pain after endodontic treatment.
