Post-operative pain assessment after different irrigant activation methods (An In vivo-study)

Abstract

This study was conducted to evaluate and compare the post-operative pain after using XP-Endo Finisher file versus ultrasonic activated irrigation versus dynamic manual irrigation in the final irrigation protocol in single visit endodontic treatment of symptomatic irreversible pulpitis. Fifty six patients with symptomatic irreversible pulpitis, mandibular molars teeth were endodontically treated in a single visit. The patients were divided into 3 groups, each consisted of 18 patients. Instrumentation was done using Fanta rotary file system. Irrigation was done using 2.5% NaOCl. Final irrigation step was either using XP-Endo Finisher f ultrasonic activated irrigation or manual dynamic agitation. Postoperative pain was assessed using a Numerical Pain Rating Scale at 6, 24, 48hours. All demographic data, clinical findings and numerical rating scale scores obtained from the patients were statistically analyzed. When comparing the median of NRS scores in the three groups, there was no statistically significant difference between them after 6, 24, 48 hours postoperatively.
