An In Vivo Evaluation of postoperative pain after root canal instrumentation using manual K-files and Kedo-S rotary files in primary molars

Abstract

Aim: To determine postoperative pain after root canal instrumentation using manual K-file and rotary Kedo-S files in primary molars. Material and Method: Thirty-six primary mandibular molars from 4- to 8-year-old children requiring pulpectomy were randomly split into two groups of 18 teeth each, that is, manual file K-file (Group I) and Kedo-S rotary file (Group II). Children's pre- and postoperative pain was assessed using a four-point scale at different time intervals. Results: From the result of the present study, it was observed that the Kedo-S group showed significantly less pain after 24, 48, and 72 h. Conclusion: It was concluded from the present research that patients enrolled in the Kedo-s group experienced less pain.
