Evaluation of Post-Operative Pain Subsequent to Endodontic Treatment Utilizing Hand and Pedoflex Rotary files in Primary Mandibular Molars: A Clinical Investigation

Aim: To comparatively evaluate postoperative pain levels following root canal instrumentation with hand files versus Pedoflex rotary files in primary mandibular molars. Material and Methods: This randomized clinical trial involved 60 children aged 6-10 years with primary mandibular molars requiring pulpectomy. They were divided into two groups: Group I received hand K file instrumentation, and Group II was treated with Pedoflex rotary files. Pain levels were recorded using the Wong-Baker FACES Pain Rating Scale at 6, 12, 24, 48, and 72 hours postoperatively. Results: The Pedoflex rotary file group experienced significantly lower pain scores at all time intervals compared to the hand K file group (p<0.05). The mean pain score in Group A gradually decreased from 6 to 72 hours, while Group B showed a more rapid decline in the first 24 hours followed by a plateau. Conclusion: The use of Pedoflex rotary files for root canal instrumentation in primary mandibular molars significantly reduces postoperative pain when compared to conventional hand files. These findings suggest that rotary files may provide a more comfortable postoperative experience for pediatric patients undergoing pulpectomy
