What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Control Established Plaque in Adults
Time Frame: 6 weeks
Units on a scale 0 to 5 (0 = no plaque, 1 = separate flecks of plaque on the tooth, 2 = a thin continuous band of plaque, 3 = a band of plaque up to one-third of the tooth, 4 = plaque covering up to two thirds of the of the tooth, 5 = plaque covering two-thirds or more of the crown of the tooth. Total Plaque score=sum of all scores divided by the number of sites (teeth) scored.
6 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Control Gingivitis in Adults
Time Frame: 6 weeks
Gingivitis Index (GI) is described as Units on a scale 0 to 3 (0 = no inflammation,1 = Mild inflammation - slight change in color and little change in texture 2 = Moderate inflammation - moderate glazing, redness, edema and hypertrophy. Tendency to bleed upon probing. 3 = Severe inflammation-marked redness and hypertrophy. Tendency to spontaneous bleeding. GI score = Sum of all scores divided by the number of sites (teeth scored).
