The Effect of Final Irrigation Agitation techniques on Post-Operative Pain After Single Visit Root Canal Treatment of Symptomatic Irreversible Pulpitis (Randomized Clinical Trial)

Objectives: To evaluate the degree of postoperative pain and rate of analgesic intake in patients having symptomatic pulpitis in mandibular first molar teeth at 6h, 12h, 24h, 48h, and 72h after using different irrigation activation techniques in single-visit endodontic treatment.
Subjects and Methods: Seventy-eight patients with symptomatic irreversible pulpitis with no signs of periapical pathology were randomly divided into three groups according to the final irrigation activation technique Group; A, XP endo finisher; Group B, Ultra X ultrasonic device; Group C, side vented needle. The teeth underwent standardized single visit root canal treatment procedures using 2.5% sodium hypochlorite for irrigation. Each patient was given a chart to record postoperative pain at a 6-, 12-, 24-, 48- and 72-hours intervals. Ibuprofen 400 mg tablets were prescribed to be taken when the pain is unbearable. The incidence and/or number of analgesic tablets taken were recorded. Data were analyzed using Kruskal Wallis test followed by pairwise Mann-Whitney U test with bonferroni correction for intergroup comparisons and Freidman’s test followed by dunn’s post hoc test for intragroup comparisons.
Results: No statistically significant difference was found between all groups regarding the incidence and intensity of pain at different time intervals (p>0.05). There was no significant difference in analgesic intake between different groups with most of the cases in all groups not taking analgesics (p>0.05).
Conclusion: Adding XP-Endo Finisher or Passive Ultrasonic Irrigation to the irrigation protocol in single visit endodontic treatment had no significant effect on postoperative pain or analgesic intake. (EEJ-2021-11-185)
