Adjunctive Ozone Therapy for Residual Periodontal Pockets
Turkey (Türkiye)26 participantsStarted 2024-03-15
Plain-language summary
Patients with residual periodontal pockets following non-surgical periodontal therapy remain at risk for disease progression and may require further periodontal surgery. Repeated scaling and root planing (SRP) is commonly used for residual pockets; however, complete elimination of periodontal pathogens is often difficult to achieve. Ozone therapy has antimicrobial, anti-inflammatory, and wound-healing properties that may improve periodontal treatment outcomes.
The aim of this randomized controlled clinical trial is to clinically and microbiologically evaluate the adjunctive effects of gaseous ozone application during repeated SRP for residual periodontal pockets in patients undergoing periodontal maintenance therapy. Twenty-six patients diagnosed with stage III or IV periodontitis presenting with residual periodontal pockets ≥5 mm with bleeding on probing will be included. Residual pockets will be randomly assigned to either repeated SRP alone (control group) or repeated SRP combined with ozone application (test group).
Clinical periodontal parameters and microbiological findings will be evaluated at baseline, 3 months, and 6 months after treatment.

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?
