Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: AFEO-Containing Mouth Rinse<br>Participants with Diabetes (Type 1 and 2) will be randomized to receive AFEO-containing mouth rinse with a marketed fluoride-containing dentifrice, floss (if flossing is part of their normal oral care routine), a marketed soft bristled toothbrush and a timer (if needed). They will brush for at least one minute using full ribbon of a marketed toothpaste on the provided toothbrush. After brushing, rinse for 30 seconds with 20 milliliter (mL) of the assigned mouth rinse twice daily (morning and evening) for 12 consecutive Weeks. | Other: Colgate Cavity Protection Toothpaste<br>* Participants used Colgate cavity protection toothpaste for brushing teeth twice daily.<br>Other: Alcohol-Free Essential Oil Containing (AFEO) Mouth Rinse Lead Formula<br>* Participants use 20 mL of AFEO mouth rinse lead formula for 30 sec after brushing.<br>Device: Concept Curve Winter Series Toothbrush<br>* Participants will brush teeth at least one minute with provided bristled toothbrush.<br>Device: Listerine Cool Mint Floss<br>* Participants will use marketed fluoride-containing dentifrice, floss.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Whole-Mouth Mean Modified Gingival Index (MGI) Score After 12 Weeks of Product use | 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). | 12 Weeks | 
| Whole Mouth Mean Turesky Plaque Index (TPI) Score After 12 Weeks of Product use | 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). | 12 Weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Whole Mouth Mean Turesky Plaque Index (TPI) Score After 1 and 6 Weeks of Product use | 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). | 1 Week and 6 Weeks | 
| Whole-Mouth Mean Modified Gingival Index (MGI) Score After 6 Weeks of Product use | 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). | 6 Weeks | 
| Whole-Mouth Mean Expanded Bleeding Index (EBI) Score After 6 and 12 Weeks of Product use | 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). | 6 Weeks and 12 Weeks | 
| Percentage of Bleeding Sites, Based on the Expanded Gingival Bleeding Index Score After 6 and 12 Weeks of Product use | 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. 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). | 6 Weeks and 12 Weeks |
