Comparative evaluation of postoperative pain after single-visit endodontic treatment using protaper gold and hyflex electrical discharge machining rotary file system

Abstract

Background: Endodontics has a widened range due to its increase in success rate and increase in lifespan of individuals. As of today, extracting the tooth has become a rare situation, and endodontic intrusion has become a custom. Although after having detailed knowledge about the internal anatomy of tooth, it is a must to know about the upcoming evolution of instruments as well as materials and complete knowledge regarding techniques of treatment modalities. Postoperative pain could leave a significant control on the quality of life, which will begin after completion of endodontic treatment having a range of 3%–58% cases. Materials and Methods: Twenty-six patients with irreversible pulpitis were selected for single-visit endodontics. The teeth were blindly assigned to two groups based on the instrumentation systems used: Group A (Protaper Gold) and Group B (Electrical Discharge Machining [EDM] Hyflex). Participants were asked to note the incidence of preand postoperative pain on the Visual Analog Scale at different time intervals. Results: The greatest mean pain in both Group A and B was found to be maximum in the first 24 h, with a significant reduction in pain at the subsequent observation time points of 48 h, 72 h, and 7 days. The least painful group was Group A, followed by Group B. Conclusion: In single-visit endodontics, both Protaper Gold and EDM Hyflex both may prove to be a better system, but according to statistics Protaper gold being slightly superior as it produces minimal postoperative pain, thus improving the overall acceptance of endodontic treatment.
