Clinical Trial Evaluating Chlorine e6 Derivative-mediated Antimicrobial Photodynamic Therapy as a Treatment for Denture Stomatitis

65 participantsStarted 2015-02-01

Plain-language summary

Objective: This randomized clinical trial assessed antimicrobial Photodynamic Therapy (aPDT) mediated by Photodithazine (PDZ) to treat patients with denture stomatitis (DS). Methodologies: Patients with DS were randomly assigned to the groups: aPDT (n=30) and nystatin (NYS, n=35). aPDT patients received 6 aPDT sessions, three times a week for 15 days, which involved PDZ (200 mg/L) topical application (20 min) on the palate and upper denture, followed by light emitting diode (LED) illumination (660 nm, 50 J/cm²). NYS patients were instructed to rinse one dropper of this medication for one minute, four times a day, for 15 days. Microbiological collections of dentures and palates were performed and cultured on blood agar and CHROMAgar Candida. Microbial viability was determined, and photographs of the palates were taken for clinical evaluation. Data were analyzed by Repeated Measure Linear Model and Bonferroni (p≤0.05).

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.

What they're measuring

Microbial Viability at baseline

Timeframe: The recovery of microorganisms was performed before the tretaments (at the baseline - initial).

Microbial Viability at the end of the treatments

Timeframe: The recovery of microorganisms was performed immediately at the end of the treatments.

Microbial Viability on day 15

Timeframe: The recovery of microorganisms was performed on day 15 after the end of the treatments.

Microbial Viability on day 30

Timeframe: The recovery of microorganisms was performed on day 30 after the end of the treatments.

Microbial Viability on day 45

Timeframe: The recovery of microorganisms was performed on day 45 after the end of the treatments.
