Outcome Measures
Primary Outcome Measures
- Interproximal Mean Turesky Plaque Index (TPI) Score After 12 Weeks of Product use [12 Weeks]
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.
- Interproximal Mean Modified Gingival Index (MGI) Score After 12 Weeks of Product use [12 Weeks]
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.
Secondary Outcome Measures
- Interproximal Mean Turesky Plaque Index (TPI) Score After 4 Weeks of Product use [4 Weeks]
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.
- Interproximal Mean Modified Gingival Index (MGI) Score After 4 Weeks of Product use [4 Weeks]
