Abstract: Introduction: Postoperative pain is a common complication in endodontic procedures, influenced by various factors, including the instruments used for canal preparation and their kinematics. This study aims to compare the incidence of postoperative pain following the use of a new technique, the standard technique of the ProTaper system, and self-adjustable files in root canal preparation. Methods: This randomized, controlled, parallel clinical trial aimed to evaluate post-endodontic pain associated with three distinct root canal cleaning and shaping techniques: the standard technique, a new technique using the ProTaper system, and the self-adjusting file system. A total of 123 mature permanent teeth requiring root canal treatment (RCT) from participants aged 10 to 65 years were selected through systematic randomization. All procedures were performed by a single operator in one center, utilizing loop magnification and isolation during a single visit for cleaning and shaping the canal. The samples were categorized into three groups: Group A (Standard technique using ProTaper gold rotary files), Group B (New sequence of ProTaper gold rotary files), and Group C (Self-adjusting files). The data collected from the participants were analyzed statistically using SPSS 25. The chi-square test was applied for comparison between groups, with the level of significance set at p < 0.05. Results: The incidence of postoperative pain in the SAF group was notably lower compared to the pain levels observed with both the new technique and the standard technique of the ProTaper systems. However, there was no significant difference in pain levels between the standard and new technique methods for cleaning and shaping the canals. Additionally, patients treated with the SAF method experienced pain that was not severe enough to require painkillers, and no analgesics were utilized. Conclusion: In summary, while all instrumentation techniques may lead to some degree of postoperative pain, the results of this study favor the SAF system. It can be concluded that the SAF technique, using continuous irrigation, resulted in significantly lower pain levels compared to both the standard and new technique methods.
