Photodynamic Therapy as an Adjunct to Non-Surgical Periodontal Therapy in Stage II Periodontitis
United Arab Emirates30 participantsStarted 2023-06-01
Plain-language summary
Gum disease (periodontitis) affects millions of people worldwide and can lead to tooth loss if untreated. The standard treatment is a deep cleaning procedure called non-surgical periodontal therapy (NSPT), where a dentist removes bacterial buildup from beneath the gums. Sometimes, harmful bacteria remain after this cleaning and the disease can return.
This study tests whether adding a light-based antibacterial treatment - called photodynamic therapy (PDT) - to the standard deep cleaning improves results. PDT works by placing a harmless green dye (indocyanine green) into the gum pocket, then shining a specific laser light on it. The light activates the dye and kills the remaining bacteria without antibiotics.
Who can join: Adults aged 18 and over diagnosed with moderate gum disease (Stage II periodontitis) with gum pocket depths of 4-5 mm.
How it works: Each participant receives both treatments - standard cleaning on one side of the mouth, and standard cleaning plus PDT on the other side. This allows a fair comparison within the same person.
What is measured: Gum pocket depth, gum attachment level, and gum bleeding - checked at the start of the study and again after 3 months.
The study was conducted at Thumbay University Hospital, UAE

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?
