Purpose: This post-endodontic pain observation study aimed to evaluate the post-endodontic pain using Twisted-File (TF), TF-Adaptive (TFA), and Trunatomy (TRN) files after single visit root canal treatment
Methods: A total of 150 medically healthy patients with asymptomatic maxillary or mandibular molar teeth indicated root canal treatment were allocated into three groups for instrumentation used; Group1: TF, Group 2: TFA, and Group 3: TRN file system in a single visit. The pain level 72 hours later was questioned using a visual analog scale. Scores were analyzed using one-way ANOVA, and post hoc Tukey tests for a significance level of p<0.05.
Results: A significant difference was found between groups in terms of pain incidence (p=0.048). In the binary comparisons; there was no difference between Groups 1 and 2 (TF, TFA) (p=0.547) and there was no difference between Groups 1 and 3 (TF, 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 patient experiencing “no pain” the incidence of symptoms was higher with the TRN systems.
