Development of a Sanitizing Tablet for Removable Partial Dentures
Brazil15 participantsStarted 2026-06-08
Plain-language summary
The goal of this clinical trial is to learn if a new experimental effervescent tablet works to clean removable partial dentures. It will test if the tablet lowers bacteria and fungi on denture surfaces. The main questions it aims to answer are: Does the experimental tablet lower the number of microbes on different denture materials? How happy are participants with the taste, odor, and cleanliness of the tablet? Researchers will compare the experimental tablet to a known commercial cleanser and to a neutral water solution to see which one works best. Total participation will last 70 days. First, researchers will place small material discs on the side of the participant's current denture to collect natural plaque. Participants will wear their dentures 24 hours a day and brush them with soap and water after meals. Participants will then cycle through three separate 14-day testing phases. In each phase, participants will soak their dentures daily for 15 minutes in one of the assigned solutions. Participants will also have a 7-day break between each phase where they return to their basic regular cleaning routine. At the end of each testing phase, researchers will remove the small discs to count the microbes in a laboratory. Participants will also answer a short survey about their satisfaction with each product.

* Ability to understand and sign the Informed Consent Form.
Exclusion Criteria:
* Use of systemic antibiotics, antifungals, or anti-inflammatory drugs within the last 3 months.
* History of allergic reactions to N-acetylcysteine (NAC), Melaleuca alternifolia (tea tree) oil, or components of the commercial positive control (NitrAdine).

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?
