Effect of Instrumentation Systems and Sealers on Postoperative Pain
144 participantsStarted 2026-07-01
Plain-language summary
The goal of this randomized clinical trial is to evaluate whether different root canal preparation systems and sealer types affect postoperative pain after root canal treatment in adult patients (18-60 years) with asymptomatic irreversible pulpitis in mandibular premolars.
The main questions it aims to answer are:
Do different instrumentation systems (TruNatomy vs ProTaper Gold) influence postoperative pain levels? Do different sealer types (AH Plus vs TotalFill BC) affect postoperative pain and analgesic consumption? Researchers will compare TruNatomy and ProTaper Gold systems combined with AH Plus or TotalFill BC sealers to determine their effect on postoperative pain.
Participants will:
Undergo single-visit root canal treatment using one of the assigned file system and sealer combinations Record their pain levels using a Numerical Rating Scale (NRS) at specific time intervals (6, 12, 24, 48, 72 hours, and 7 days) Take ibuprofen only if needed and record analgesic intake Attend a follow-up visit on the 7th day

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
