Primary Outcome Measures

Name	Time	Method
Mean Turesky Plaque Index (TPI) Score After 12 Weeks of Product use	12 Weeks	Plaque area will be scored by the Turesky modification of the Quigley-Hein Plaque Index, on 6 surfaces (distobuccal, midbuccal and mesiobuccal, distolingual, midlingual and mesiolingual) of all scorable teeth, following disclosing: 0 (No Plaque); 1 (Separate flecks or discontinuous band of plaque around the gingival (cervical) margin); 2 (Thin (up to 1 millimeter \[mm\]), continuous band of plaque at the gingival margin); 3 (Band of plaque wider than 1mm but less than1/3 of the surface); 4 (Plaque covering 1/3 or more, but less than 2/3 of the surface); 5 (Plaque covering 2/3 or more of the surface).
Whole-mouth Mean Modified Gingival Index (MGI) Score After 12 Weeks of Product use	12 Weeks	Gingivitis will be assessed by the 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).

Whole-mouth Mean Modified Gingival Index (MGI) Score After 4 Weeks of Product use	4 Weeks	Gingivitis will be assessed by the 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).
Whole-mouth and Interproximal Mean Bleeding Index (BI) After 4 and 12 Weeks of Product use	4 Weeks and 12 Weeks	Bleeding will be assessed according to the Expanded Gingival Bleeding Index, 168 Sites. A periodontal probe with a 0.5 millimeter (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 6 gingival areas (distobuccal, mid-buccal, mesiobuccal, distolingual, 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).
Marginal Mean Expanded Bleeding Index (EBI) Score After 4 and 12 Weeks of Product use	4 Weeks and 12 Weeks	Bleeding will be assessed according to the Expanded Gingival Bleeding Index, 168 Sites. A periodontal probe with a 0.5 millimeter (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 6 gingival areas (distobuccal, mid-buccal, mesiobuccal, distolingual, mid-lingual, and mesiolingual) around each tooth will be assessed.

Marginal and Interproximal Mean Modified Gingival Index (MGI) Score After 4 and 12 Weeks of Product use	4 Weeks and 12 Weeks	Gingivitis will be assessed by the 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).
Whole-mouth and Interproximal Percent Bleeding Sites, Based on the EBI Score After 4 and 12 Weeks of Product use	4 Weeks and 12 Weeks	Percent bleeding sites will be calculated by taking the total number of sites with bleeding score greater than 0 divided by the total number of sites assessed for each participant. Bleeding will be assessed according to the Expanded Gingival Bleeding Index, 168 Sites. A periodontal probe with a 0.5 millimeter (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 6 gingival areas (distobuccal, mid-buccal, mesiobuccal, distolingual, mid-lingual, and mesiolingual) around each tooth will be assessed.
