    Abstract:
    PURPOSE: To investigate in a double-blind clinical study the effectiveness of a dentifrice containing triclosan and a copolymer (Colgate Total Toothpaste) for controlling breath odor 12 hours after brushing the teeth. METHODS: A panel of four expert judges using a nine-point hedonic scale evaluated breath odor. Following a baseline evaluation of breath odor, prospective study subjects who presented breath odor scores above the threshold value for unpleasant breath odor were stratified by score, and randomized into two treatment groups. Subjects were provided with a soft-bristled toothbrush, and brushed their teeth thoroughly in their regular and customary manner with their assigned dentifrice. Subjects refrained from dental hygiene, breath mints, or mouthrinses for the next 12 hours, after which they were once again evaluated for breath odor. 76 adult male and female subjects from the Mississauga, Ontario, Canada area participated in the study. RESULTS: At 12 hours after brushing their teeth, subjects in both dentifrice treatment groups presented mean breath odor scores which were statistically significantly lower than the mean scores observed at baseline. However, the difference between the mean 12-hour breath odor score for the Colgate Total group was 4.65, which is within the range of values corresponding to pleasant breath odor; whereas the mean 12-hour breath odor score for the placebo group was 6.11, which is above the threshold value corresponding to unpleasant breath odor. Thus, the results of this double-blind study, conducted according to Guidelines by the Council on Scientific Affairs of the American Dental Association, support the conclusion that Colgate Total dentifrice provides effective control of breath odor at 12 hours after brushing the teeth.
