Effect of Ozone Use in Intracanal Irrigation on Oxidative Stress Level in Teeth With Asymptomatic Apical Periodontitis

Turkey (Türkiye)60 participantsStarted 2024-09-27

Plain-language summary

This clinical study aims to investigate the oxidative stress-related effects of ozone irrigation in patients with asymptomatic apical periodontitis undergoing root canal treatment. A total of 60 patients who meet the inclusion criteria will be randomly assigned into two groups using an online randomization tool: an ozone irrigation group and a saline irrigation (control) group. The primary objective is to assess the biochemical effects of ozone therapy on oxidative stress markers in periapical interstitial fluid, including but not limited to TAS, TOS, MDA, and 8-OHdG, by using ELISA kits. After routine canal preparation and initial irrigation protocol (NaOCl-EDTA-NaOCl), baseline periapical fluid samples will be collected using standardized sterile paper points. Following this, experimental irrigation will be applied: ozone water in the study group and saline solution in the control group. Second periapical fluid samples will be collected immediately after this procedure. Subsequently, calcium hydroxide dressing will be placed into the canals, and the patients will be recalled after one week. At the second visit, after removal of the intracanal medicament, a third sample will be collected from each patient. Ethical approval was obtained from the Non-Interventional Clinical Research Ethics Committee of Atatürk University Faculty of Medicine. The results of this study are expected to contribute to the understanding of ozone therapy as a biocompatible and effective disinfection agent in endodontic procedures and to provide insights into its role in modulating oxidative stress within the periapical environment.

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.
