A Study is to Evaluate a Regimen on Gingivitis Using Traditional and Novel Assessment Methods

Subjects who have shown evidence of gingivitis and plaque will be enrolled in this study. Each subject will be randomly assigned to one of two treatment products. The regimen group will be asked to brush 2x a day in using a power brush (2 minutes of brushing), followed by using 20 ml of mouth rinse for 30 seconds for 6 weeks. The negative control group will be asked to brush 2x a day using a manual toothbrush in their customary manner for 6 weeks. Oral Soft Tissue (OST) assessments, gingivitis and plaque measurements will be taken at 4 time-points: Baseline (BL); Week 1; Week 3; and Week 6.
