Arm Intervention/treatment
Placebo Comparator: A - Marketed fluoride toothpaste Drug: Sodium Monofluorophosphate
Brush teeth and evaluate plaque score after one use of the study toothpaste
Other Name: Colgate Great Regular Flavor toothpaste

Active Comparator: B -Triclosan/NaF/CoPolymer toothpaste Drug: Triclosan/Fluoride/Copolymer
Brush teeth and evaluate plaque score after one use of the study toothpaste
Other Name: Colgate Total toothpaste

Primary Outcome Measures :
  1. Gingival Margin Plaque Index [ Time Frame: 1 day ]
    Scale 0 to 100% of tooth gingival margin covered by plaque. (0=no plaque, 100%=100% of the tooth's gingival margin is covered in plaque). The lower the score less dental plaque is present along the gum line and therefore the better the performance of the study treatment.
