What is being measured

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

  1. Interproximal Mean Turesky Plaque Index (TPI) Score After 12 Weeks of Product use

    Plaque area will be assessed using the Turesky Modification of the Quigley- Hein Plaque Index, on six surfaces (disto-buccal, mid-buccal, mesio-buccal and disto-lingual, mid-lingual, and mesio-lingual) of all scorable teeth, following disclosing: 0 - No plaque; 1 - Separate flecks or discontinuous band of plaque at the gingival (cervical0 margin); 2- Thin (up to 1 millimeter), continuous band of plaque at the gingival margin; 3 - Band of plaque wider than 1 mm but less than 1/3 of surface; 4 - Plaque covering 1/3, but less than 2/3 of surface; 5 - Plaque covering 2/3 or more of a surface.

    Measured: 12 Weeks

  2. Interproximal Mean Modified Gingival Index (MGI) Score After 12 Weeks of Product use

    Gingivitis will be assessed using Modified Gingival Index on the buccal and lingual marginal gingivae and interdental papillae of all scorable teeth: 0- Normal (absence of inflammation); 1- Mild inflammation (slight change in color, little change in texture) of any portion of the entire gingival unit; 2- Mild inflammation of the entire gingival unit; 3- Moderate inflammation (moderate glazing, redness, edema, and/or hypertrophy) of the gingival unit; 4- Severe inflammation (marked redness and edema/hypertrophy, spontaneous bleeding, or ulceration) of the gingival unit.

    Measured: 12 Weeks

Secondary outcomes (7)
  1. Interproximal Mean Turesky Plaque Index (TPI) Score After 4 Weeks of Product use

    Plaque area will be assessed using the Turesky Modification of the Quigley- Hein Plaque Index, on six surfaces (disto-buccal, mid-buccal, mesio-buccal and disto-lingual, mid-lingual, and mesio-lingual) of all scorable teeth, following disclosing: 0 - No plaque; 1 - Separate flecks or discontinuous band of plaque at the gingival (cervical0 margin); 2- Thin (up to 1 millimeter), continuous band of plaque at the gingival margin; 3 - Band of plaque wider than 1 mm but less than 1/3 of surface; 4 - Plaque covering 1/3, but less than 2/3 of surface; 5 - Plaque covering 2/3 or more of a surface.

    Measured: 4 Weeks

  2. Interproximal Mean Modified Gingival Index (MGI) Score After 4 Weeks of Product use

    Gingivitis will be assessed using Modified Gingival Index on the buccal and lingual marginal gingivae and interdental papillae of all scorable teeth: 0- Normal (absence of inflammation); 1- Mild inflammation (slight change in color, little change in texture) of any portion of the entire gingival unit; 2- Mild inflammation of the entire gingival unit; 3- Moderate inflammation (moderate glazing, redness, edema, and/or hypertrophy) of the gingival unit; 4- Severe inflammation (marked redness and edema/hypertrophy, spontaneous bleeding, or ulceration) of the gingival unit.

    Measured: 4 Weeks

  3. Whole-mouth Mean Turesky Plaque Index (TPI) Score After 4 Weeks and 12 Weeks of Product use

    Plaque area will be assessed using the Turesky Modification of the Quigley- Hein Plaque Index, on six surfaces (disto-buccal, mid-buccal, mesio-buccal and disto-lingual, mid-lingual, and mesio-lingual) of all scorable teeth, following disclosing: 0 - No plaque; 1 - Separate flecks or discontinuous band of plaque at the gingival (cervical0 margin); 2- Thin (up to 1 millimeter), continuous band of plaque at the gingival margin; 3 - Band of plaque wider than 1 mm but less than 1/3 of surface; 4 - Plaque covering 1/3, but less than 2/3 of surface; 5 - Plaque covering 2/3 or more of a surface.

    Measured: 4 Weeks and 12 Weeks

  4. Whole-mouth Mean Modified Gingival Index (MGI) Score After 4 Weeks and 12 Weeks of Product use

    Gingivitis will be assessed using Modified Gingival Index on the buccal and lingual marginal gingivae and interdental papillae of all scorable teeth: 0- Normal (absence of inflammation); 1- Mild inflammation (slight change in color, little change in texture) of any portion of the entire gingival unit; 2- Mild inflammation of the entire gingival unit; 3- Moderate inflammation (moderate glazing, redness, edema, and/or hypertrophy) of the gingival unit; 4- Severe inflammation (marked redness and edema/hypertrophy, spontaneous bleeding, or ulceration) of the gingival unit.

  5. Whole-mouth and Interproximal Mean Bleeding Index (BI) After 4 and 12 Weeks of Product use

    Bleeding will be assessed according to the Gingival Bleeding Index. A periodontal probe with a 0.5 mm diameter tip will be inserted into the gingival crevice and swept from distal to mesial around the tooth at an angle of approximately 60 degree, while in contact with the sulcular epithelium. Each of 4 gingival areas (distobuccal, mid-buccal, mid-lingual, and mesiolingual) around each tooth will be assessed. After approximately 30 seconds, bleeding at each gingival unit will be recorded according to the following scale: 0- Absence of bleeding after 30 seconds; 1- Bleeding after 30 seconds; 2- Immediate bleeding.

    Measured: 4 Weeks and 12 Weeks

  6. Whole-mouth and Interproximal Percent Bleeding Sites, Based on the BI Score After 4 and 12 Weeks of Product use

    Bleeding will be assessed according to the Gingival Bleeding Index. A periodontal probe with a 0.5 mm diameter tip will be inserted into the gingival crevice and swept from distal to mesial around the tooth at an angle of approximately 60 degree, while in contact with the sulcular epithelium. Each of 4 gingival areas (distobuccal, mid-buccal, mid-lingual, and mesiolingual) around each tooth will be assessed.

Distal proximal and mesial proximal will be assessed on all teeth including the distal of the second molar using the following scoring system: 0- No plaque; 1 - Separate flecks of plaque covering less than 1/3 of the area; 2 - Discrete areas or bands of plaque covering less than 1/3 of the area; 3 - Plaque covering 1/3 of the area; 4 - Plaque covering more than 1/3 but less than 2/3 of the area; 5 - Plaque covering 2/3 or more of the area.

    Measured: 4 Weeks and 12 Weeks

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Colgate Cavity Protection Toothpaste, American Dental Association (ADA) Referenced Toothbrush and 5% Hydroalcohol Mouth Rinse in people with Healthy, run by Johnson & Johnson Consumer Inc. (J&JCI) at 1 site in United States.

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 8 inclusion and 5 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 28 Sep 2021. 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 United States. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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?

Interproximal Mean Turesky Plaque Index (TPI) Score After 12 Weeks of Product use (time frame: 12 Weeks). The study lists 2 primary outcomes in all. 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 NCT04696536, which also lists 3 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 28 Sep 2021.
