Methods: A total of 150 healthy patients with asymptomatic maxillary or mandibular molar teeth iden- tified for root canal treatment were allocated into three groups according to the instrumentation tech- nique used: Group 1 (TF), Group 2 (TFA), and Group 3 (TRN) file systems were used in a single visit. The pain level after 72 h was questioned using a visual analog scale. Scores were analyzed using the Chi- square test with a significance value of p< 0.05. Results: A significant difference was found between groups in terms of pain incidence (p = 0.048). In the pairwise comparison, there was no difference between Groups 1 and 2 (TF and TFA) (p = 0.547), and there was no difference between Groups 1 and 3 (TF and TRN) (p = 0.201). A significant difference was found between Group 2 (TFA) and Group 3 (TRN) in terms of pain incidence (p = 0.007). Conclusion: All file systems used in the study caused post endodontic pain. When evaluating patients experiencing “no pain,” the incidence of symptoms was higher with the TRN systemeninfo:eu-repo/semantics/openAccessArticle10.14744/TEJ.2022.46220120311611663157
