The objective of this randomized, crossover study was to compare the effectiveness of Colgate Total Advanced Fresh toothpaste to a commercially available breath-freshening dentifrice containing fluoride for its ability to reduce volatile sulfur compounds (VSC) responsible for breath odor overnight. The study followed a two-treatment, two-period crossover design. Subjects were given a test product, along with a soft-bristled toothbrush, and instructed to brush their teeth for 1 minute, twice daily (once in the morning and the evening) using the assigned dentifrice for 7 consecutive days. After their evening brushing on the seventh day, subjects reported to the testing facility without oral hygiene, eating, or drinking for the overnight evaluation. After a washout period, subjects repeated the same regimen, now using the other test product. The levels of breath VSC were evaluated instrumentally using a gas chromatograph equipped with a flame photometric detector.
