Group 1: Listerine Cool Mint Mouth Rinse (Marketed product)Colgate Cavity Protection ToothpasteParticipants will receive Alcohol-containing Essential Oil (AEO) containing mouth rinse (Listerine Cool Mint, marketed) orally for 12 weeks.

Primary Outcome Measures
NameTimeMethod
Interproximal Mean Turesky Plaque Index (TPI) Score After 12 Weeks of Product use12 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 use12 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
NameTimeMethod
Whole-mouth Mean Modified Gingival Index (MGI) Score After 4 Weeks and 12 Weeks of Product use4 Weeks and 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.

Whole-mouth and Interproximal Mean Bleeding Index (BI) After 4 and 12 Weeks of Product use4 Weeks and 12 Weeks

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.

Interproximal of the Proximal Marginal Plaque Index Score After 4 and 12 Weeks4 Weeks and 12 Weeks

Interproximal Plaque area will be assessed using the PMI on the facial and lingual surfaces. 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.
