What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Dental Plaque Scores	Dental Plaque (Quigley-Hein, Turesky Modification Index) 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)	Baseline
Gingivitis Scores	Gingivitis scale (Loe & Silness Gingival Index) 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)	Baseline
