Comparative evaluation of postoperative pain between rotary and reciprocating files

Lukka Jagadish, Aswathy Krishna

Background: During the root canal preparation procedures, dentin chips, pulp tissue, microorganisms and/or irrigants may get extruded into the periradicular tissues. Postoperative pain, which is an undesirable complication, is frequently encountered and found to range between 3% and 58% in root canal treatment. Hence; the present study was planned for evaluation and comparison of postoperative pain between rotary and reciprocating files. Materials & Methods: A total of 50 patients were enrolled in the present study.All the patients were broadly and randomly divided into two study groups as follows:Group 1: 25 patients in whom treatment was carried out using XPS files (continuous rotary single file system), andGroup 2: 25 patients in whom treatment was carried out using REC Blue files (reciprocating single file system).Root canal therapy was carried out in all the patients according to their respective study groups. Visual analog scale (VAS) was used for pain assessment. On a scale of 1 to 10, patients were asked to grade the pain at 24-hour, 48 hour and 1 week postoperative interval. Pain was categorized on the basis of VAS as no pain (0), mild pain (1–3), moderate pain (4–6) and severe pain (7–10). All the results were recorded in Microsoft excel sheet and were analyzed by SPSS software. Results: Mean VAS at 24 hour postoperatively among patients of group 1 and group 2 was found to be 0.87 and 2.11 respectively. Significant results were obtained while comparing the mean VAS among patients of both the study groups at 24 hours postoperatively. Mean VAS at 48 hour postoperatively among patients of group 1 and group 2 was found to be 0.71 and 1.23 respectively. Significant results were obtained while comparing the mean VAS among patients of both the study groups at 48 hours postoperatively. Mean VAS at 1 week postoperatively among patients of group 1 and group 2 was found to be 0.10 and 0.25 respectively. Non- significant results were obtained while comparing the mean VAS among patients of both the study groups at 1 week postoperatively. Conclusion: files are associated with lesser postoperative pain in comparison to reciprocating files in patients undergoing root canal therapy.
