About this study

Official title: A Double Blind Randomized, Placebo-controlled, Cross-over Trial to Evaluate the Efficiency of a Mouthrinse, Containing Red Grape Seed Extract and nicométhanol Fluorhydrate, in the Control of Dental Plaque Deposit in a 4-days Plaque Regrowth Model

The objective of this study is to evaluate the efficiency of a new mouthrinse on dental plaque deposits.

The study is carried out on 50 volunteers that are asked to use the mouthrinse without any other oral hygiene measure, during 4 days. It is a double bind, cross-over, randomized design: the same subjects test the active product and the placebo.

Read the detailed description

The prevention of oral diseases is mainly targeted at the control of dental plaque. While tooth brushing is an effective method to remove plaque mechanically, it is not always sufficient and chemical antiplaque agents could be helpful. Some of them are used for their antibacterial action, the gold standard being chlorhexidine. Despite the great benefit of this bactericidal approach, the search continues for active ingredients that could prevent dental plaque formation without affecting the biological equilibrium within the oral cavity.

The aim of this study is to evaluate the efficiency of a mouthrinse, containing red grape seed extract and nicométhanol fluorhydrate, in the control of dental plaque deposit in a 4-days plaque regrowth model.

The study is a double blind randomized cross-over design, involving 50 healthy volunteers. During the treatment periods (4 days) no oral hygiene, measures excepting rinsing with the allocated product (active/non active) are permitted.

On day 1, the subjects receive professional prophylaxis. The mouthrinse is used pure, three times per day, after each meal. On day 5, subjects will be scored for disclosed plaque using the Quigley Hein index (modified by Turesky).

After a 2 weeks wash-out period, the subject receives the other product (active/non active) and uses it as in the first period.

On day 5, subjects will be scored again for disclosed plaque

What is being measured

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

  1. Plaque index of Quickley-Hein modified by Tureski. Plaque deposits are scored on all natural teeth (except third molars) after staining.

    Measured: Measures are done on days 5 of the two plaque growth periods

Secondary outcomes (2)
  1. Product tolerance

    Measured: on days 5 of the two plaque growth periods

  2. Product acceptability (oral sensation)

    Measured: on days 5 of the two plaque growth periods

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing mouthrinse (Grape Seed Extract + nicomethanol fluorhydrate) and mouthrinse containing non-active component in people with Dental Plaque, run by University Hospital, Bordeaux at 1 site in France.

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 6 inclusion and 15 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 2 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Plaque index of Quickley-Hein modified by Tureski. Plaque deposits are scored on all natural teeth (except third molars) after staining. (time frame: Measures are done on days 5 of the two plaque growth periods). 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 NCT00838266, which also lists 4 linked publications.

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 2 Jun 2026.
