Arm Intervention/treatment
Placebo Comparator: A
fluoride toothpaste from Thailand
Drug: Fluoride
Brush half mouth once with assigned study treatment

Active Comparator: B
fluoride/triclosan/copolymer toothpaste
Drug: Fluoride and triclosan
Brush half mouth once with assigned study treatment
Other Name: Colgate Total toothpaste

Primary Outcome Measures :
  1. Triclosan Concentration in Dental Plaque [ Time Frame: 12 hours ]
    Triclosan is analyzed by gas chromatography (GC) with Atomic Emission Detection (480 nm) and quantitated by determining the ration of the peak height of triclosan to the peak height of an internal standard and relating the result to corresponding ratios of calibration standards.
