Effects of Different Root Canal Filling Materials and Irrigation Agitation Techniques on Postoperative Pain in Teeth With Irreversible Pulpitis: A Randomized Clinical Trial

Sponsor: Ankara University

Summary

This clinical study is designed to evaluate the effects of different irrigation agitation techniques and root canal sealers on postoperative pain and oral health-related quality of life in patients with symptomatic irreversible pulpitis. Postoperative pain following root canal treatment may affect patient comfort and satisfaction. The choice of irrigation agitation technique and root canal sealer may influence these outcomes. Irrigation agitation techniques are used to improve cleaning of the root canal system. XP-Endo Finisher, EDDY, and passive ultrasonic activation use different mechanisms to enhance this process. Root canal sealers, including the epoxy resin-based AH Plus and the calcium silicate-based NeoSealer Flo, also differ in their composition and biological properties. Clinical evidence regarding the combined effects of these techniques and sealers on patient-reported outcomes remains limited. In this randomized clinical trial, 324 patients aged 18-65 years requiring root canal treatment for a single-rooted, single-canal permanent tooth with symptomatic irreversible pulpitis will be allocated to six groups. Each group will receive one of three irrigation agitation techniques-XP-Endo Finisher, EDDY, or passive ultrasonic activation-in combination with either AH Plus or NeoSealer Flo. Root canal treatment will be completed in a single visit. Postoperative pain intensity will be assessed using a visual analog scale at 6, 12, 24, 48, and 72 hours and 7 days after treatment. Oral health-related quality of life will be assessed using the Oral Health Impact Profile-14 questionnaire before treatment and 7 days afterward. Analgesic use during the follow-up period will also be recorded. The primary objective is to compare postoperative pain among the six treatment groups. Secondary objectives include evaluating changes in oral health-related quality of life and analgesic consumption. The study will also investigate whether irrigation agitation techniques and root canal sealers have interacting effects on postoperative pain. The findings may help clinicians select irrigation agitation techniques and root canal sealers that support patient comfort and improve the patient experience following root canal treatment.
