Comparative investigation of a dentifrice containing triclosan/copolymer/sodium fluoride and specially-designed silica and a dentifrice containing 0.243% sodium fluoride in a silica base for the control of established supra-gingival plaque and gingivitis: a 6-month clinical study.
OBJECTIVE
To investigate the efficacy of a dentifrice containing 0.3% triclosan, 2.0% PVM/MA copolymer, 0.243% sodium fluoride, and specially-designed silica in controlling established dental plaque and gingivitis.


METHODS
Qualifying adult male and female subjects from the West Palm Beach, Florida area were randomly assigned into one of two treatment groups: (1) a dentifrice containing 0.3% triclosan, 2.0% PVM/MA copolymer, 0.243% sodium fluoride, and specially-designed silica (Test Dentifrice); and (2) a dentifrice containing 0.243% sodium fluoride in a silica base (Negative Control Dentifrice). All subjects received an oral soft and hard tissue examination, baseline plaque and gingivitis were assessed, and subjects were dispensed their assigned dentifrice product along with a soft-bristled adult toothbrush for home use. Subjects were instructed to brush their teeth for 1 minute, twice daily (morning and evening), using only the dentifrice provided. Examinations for plaque and gingivitis, and oral soft and hard tissue assessments were repeated after 3 and 6 months of product use.


RESULTS
115 subjects complied with the protocol, and completed the 6-month examination. After 6 months of product use, subjects assigned to the Test Dentifrice group exhibited statistically significant reductions from baseline with respect to Plaque Index, Plaque Severity Index, Gingival Index, and Gingivitis Severity Index scores; and subjects assigned to the Negative Control Dentifrice group exhibited statistically significant reductions from baseline with respect to Gingival Index scores only. Relative to the Negative Control Dentifrice group, the Test Dentifrice group exhibited an 18.8% reduction in Plaque Index; a 50% reduction in Plaque Severity Index; a 19.6% reduction in Gingival Index; and a 60% reduction in Gingivitis Severity Index after 6 months, all of which were statistically significant.
