Evaluation of the Impact of Different Final Irrigation Activation Modes on Healing of Periapical Lesions Related to Permanent Mandibular First Molars Using CBCT.
Egypt52 participantsStarted 2025-01-15
Plain-language summary
The goal of this clinical trial is to learn how different ways of activating the cleaning liquid (irrigation) during endodontic treatment affect healing of infections at the root tip (periapical lesions) in adults aged 20 to 40 with a lower first molar tooth.
The main question it aims to answer is:
Does the way the cleaning liquid is moved inside the tooth during endodontic treatment change how well the infection at the root tip heals after 12 months?
Researchers will compare four irrigation methods to see which one helps the infection heal best:
A regular needle and syringe (the standard endodontic method) Ultra X, which uses sound waves to push the liquid through the tooth Endo Vac, which uses gentle suction to pull the liquid through the tooth I Vac, which combines suction and sound waves
Participants will:
Have their endodontic treatment done in one visit by the same dentist Be randomly placed into one of the four groups Return for check-ups at 3, 6, and 9 months after endodontic treatment Come back at 12 months for a final check-up and a 3D dental scan (CBCT) to measure how much the infection has healed

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?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
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?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
