  • Agree to return for scheduled visits and follow the study procedures;
  • Agree to refrain from use of any non-study oral hygiene products for the duration of the study;
  • Agree to delay any elective dentistry, including dental prophylaxis, until the completion of the study.

Exclusion criteria

Exclusion Criteria:

  • Having taken medications (antibiotic, anti-inflammatory, or anti-coagulant) which could alter gingival bleeding within 4 weeks of the Baseline Visit;
  • Having any oral conditions that could interfere with study compliance and/or examination procedures, such as widespread caries, soft or hard tissue tumor of the oral cavity, or advanced periodontal disease;
  • Having known to the test products;

Terms in these criteria, in plain language(2)

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.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

What researchers measure

Primary outcomes

  1. Number Bleeding Sites

    Number of bleeding sites derived from the Löe-Silness Gingivitis Evaluation based on a validated assessment of gingival health looking at inflammation and bleeding based on a 4 point range 0 (normal gingiva) to 3 (severe inflammation).

    Time frame: 3 months, 1 month

Secondary outcomes

  1. Löe-Silness Gingivitis Evaluation

    Löe-Silness Gingivitis Evaluation is a validated assessment of gingival health looking at inflammation and bleeding based on a 4 point range 0 (normal gingiva) to 3 (severe inflammation).

    Time frame: 3 months, 1 month

Timeline

Tracking 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

Ran from Mar 2022 to primary completion in Jun 2022, 2 months.

Of 43 interventional studies with no phase under Gingival Diseases, half reached primary completion within 15 months of starting (the median), counting those still running; a quarter within 7 and three quarters within 25. This study's 2 months is below 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.
No changes since tracking began. The registry record was last updated on Oct 26, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
