Study summary

Qualified subjects will be enrolled and randomized to either one of the three study groups described above based on their initial modified gingivitis and plaque scores. Subjects will be instructed to use the products according to the instructions provided. Subjects will return to the dental office for evaluation after three months and six months of product use. All subjects will be followed for adverse events throughout the study.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Lobene Modified Gingivitis Assessment

    Modified Gingivitis Index score from 0 to 4 will be assigned by the examining dentist to all tooth surfaces using a dental light and dental mirror. A whole mouth mean score for each subject will be determined by adding the values given by the examining dentist to each scoreable surface and dividing that number by the total number of surfaces scored

    Time frame: Baseline, 3 month, 6 month

  2. Saxton Gingival Bleeding Assessment

    Gingival bleeding is assessed 30 seconds after probing; a score of 0 represents an absence of bleeding, a score of 1 is given if bleeding is observed within 30 seconds after probing and a score of 2 is given if bleeding is observed immediately on probing

    Time frame: Baseline, 3 month, 6 month

  3. Modified Quigley-Hein Plaque Index

    First using a red dye solution to disclose the plaque, a Modified Quigley-Hein Plaque Index score of 0 to 5 will be assigned to all scoreable disclosed tooth surfaces using a dental light and dental mirror. A whole mouth score for each subject will be determined by adding the values given by the dental examiner to each scoreable surface and dividing that number by the total number of surfaces scored.

    Time frame: Baseline, 3 month, 6 month

Timeline

1 registry update since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Jul 2026 (actual). Primary completion is estimated for Jan 2027, 6 months after the start.

Of 20 phase 3 interventional studies under Dental Plaque, half reached primary completion within 2 months of starting (the median), counting those still running; a quarter within 1 and three quarters within 4. This study's planned 6 months is above that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
