Flapless Periodontal Regeneration Using Hyaluronic Acid Versus Enamel Matrix Derivative
Spain60 participantsStarted 2024-10-26
Plain-language summary
The goal of this clinical trial is to radiographically assess the effectiveness of minimally invasive non-surgical technique (MINST) combined with local administration of sodium hypochlorite gel (Perisolv®) and 1.6% cross-linked hyaluronic acid (HA, Hyadent BG®) compared to a neutral formulation of EDTA (Prefgel®) and enamel matrix derivative (EMD, Emdogain® FL) in periodontal regeneration. The main questions it aims to answer are:
* ¿Does the combination of MINST with the local administration of sodium hypochlorite gel and 1.6% cross-linked hyaluronic acid show a potential for periodontal regeneration similar to evaluating clinical and radiographic variables compared to a neutral formulation of EDTA and enamel matrix derivative?
* ¿What is the patient perception and satisfaction with the received treatment?
Researchers will compare A (MINST with Perisolv® + Hyadent BG®), B (MINST with PrefGel® + Emdogain® FL) and C(MINST without any bioactive product).
The sample will be distributed according to the following treatments:
* Experimental group: Scaling and root planing (SRP), MINST with Perisolv® + Hyadent BG®.
* Active comparator group: SRP, MINST with PrefGel® + Emdogain® FL.
* Control group: SRP, MINST without any bioactive product.
Patients will be screened by a first visit in which they will be assigned their periodontal status. If they meet the eligibility criteria, they will be treated according to the EFP clinical guideline for periodontitis treatment: step I and step II.If the periodontal defect persists at the 12-week re-evaluation, patients will be randomised to treatment A, B or C.
After the intervention, all participants will be checked weekly for the first 6 weeks to remove accumulated plaque, and every 3 months for 1 year. Periodontal parameters will be re-evaluated 6 and 12 months after periodontal regenerative intervention.

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?
