About this study

Official title: Treatment of Peri-implant Mucositis by Non-surgical Debridement and Adjunctive Application of a Combination of Sodium Hypochlorite Gel and Cross-linked Hyaluronic Acid Gel

The aim of the study is to evaluate the potential of the combination of a sodium hypochlorite-based gel and a hyaluronic acid-based gel as an adjuvant to Non-Surgical Mechanical Debridement (NSMD) in the treatment of mucositis, after 6 months of follow-up. After a meticulous selection, patients will be randomly assigned to Test (Sodium Hypochlorite-based gel + NSMD + Hyaluronic Acid-based gel ) or Control (NSMD) group. All clinical parameters will be recorded and the final evaluation will be performed.

Read the detailed description

The aim of the study is to evaluate the clinical results of the combination of a sodium hypochlorite-based gel (NaOCl gel) and a cross-linked hyaluronic acid-based gel (HA gel) as an adjuvant to Non-Surgical Mechanical Debridement (NSMD) in the treatment of mucositis, after 6 months of follow-up (Clean \& Seal concept). Following the selection through inclusion and exclusion criteria, all patients will be randomly assigned to Test NaOCl-based gel + NSMD + HA-based gel) or Control (NSMD) group.

Patients will be recruited at Department of Periodontology (Univeristy of Naples "Federico II") and at Department of Periodontology (University of Budapest "Semmelweis").

Subsequently, after recording of the clinical parameters (BoP, FMPS, FMBS, PD), in the Test group a NaOCl-based gel will initially be applied in the peri-implant sulcus for 30 seconds, without the need for flushing. Furthermore, mechanical therapy (NSMD) will be performed by means of an ultrasonic scaler with a plastic tip. Finally, HA-based gel will be applied in the peri-implant sulcus by means of a blunt-tipped needle. Conversely, Control group will be treated only through the NSMD.

All clinical parameters (BoP, FMPS, FMBS, PD) will be recorded again after 6 months for the final evaluation. Data analysis will be performed using statistical software.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change of BoP (+/-)

    Bleeding on periodontal probing

    Measured: baseline, 6 months after periodontal therapy

Secondary outcomes (3)
  1. Change of Full-mouth Plaque Score (FMPS; %)

    Percentage of all sites exhibiting plaque

    Measured: baseline, 6 months after periodontal therapy

  2. Change of Full-mouth Bleeding Score (FMBS; %)

    Percentage of all sites exhibiting bleeding

    Measured: baseline, 6 months after periodontal therapy

  3. Change of Probing Depth (PD; millimeters).

    Distance from the gingival margin to the bottom of the peri-implant pocket

    Measured: baseline, 6 months after periodontal therapy

Questions about this trial

What is this clinical trial studying?

A study testing Application NaOCl gel + HA gel and Non-surgical mechanical debridement in people with Peri-implant Mucositis and Mucositis Oral, run by Federico II University at 2 sites in 2 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 24 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Hungary, Italy. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change of BoP (+/-) (time frame: baseline, 6 months after periodontal therapy). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05926297, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Dec 2025.
