Comparing Two Root Canal Cleaning Methods and Activation Techniques to Reduce Pain After Single-Visit Endodontic Retreatment in Adults

What this Trial Is About

This clinical trial investigates the link between various root canal irrigation techniques and the pain experienced after root canal treatment, specifically focusing on single-visit endodontic retreatment for patients with apical periodontitis. The study is designed as a prospective randomized clinical trial led by TC Erciyes University, aiming to compare the effects of different irrigation protocols and activation methods on postoperative pain. Participants will be randomly assigned to one of four experimental groups combining different irrigation solutions and activation techniques NaOClEDTA with either Conventional Needle Irrigation CNI or Passive Ultrasonic Activation PUA, and NaOClDual Rinse HEDP with either CNI or PUA. These methods are evaluated for their impact on pain after the procedure. The trial includes a single treatment visit and follows participants for 3 to 5 months to assess outcomes. During the study, participants will complete surveys to evaluate postoperative pain following the root canal retreatment. The research team will monitor and analyze pain levels related to the irrigation techniques. The total participation duration spans several months, with assessments conducted during this period to understand the relationship between treatment methods and patient pain experience.
