Outcome Measures
Primary Outcomes (6)
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

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)

Study Arms (3)
Control toothpaste
PLACEBO COMPARATOR1450 ppm Fluoride toothpaste
Experimental toothpaste
EXPERIMENTAL1450 ppm sodium fluoride toothpaste with a zinc base
Active comparator
ACTIVE COMPARATOR1450 ppm sodium fluoride/triclosan toothpaste
Interventions
1450 ppm fluoride toothpaste control - Subjects will brush their whole mouth with the control toothpaste 2 times/day for 1 minute each time and rinse with water after brushing. This daily brushing routine will continue for the six (6) month study.
1450 ppm sodium fluoride/zinc base toothpaste - Subjects will brush their whole mouth with a fluoride/zinc toothpaste 2 times/day for 1 minute each time and rinse with water after brushing. This daily brushing routine will continue for the six (6) month study.
1450 ppm sodium fluoride/triclosan toothpaste - Subjects will brush their whole mouth with this toothpaste 2 times/day for 1 minute each time and rinse with water after brushing. This daily brushing routine will continue for the six (6) month study.
