ABSTRACT
OBJECTIVE:
This study analyzed, from a combined clinical and molecular biologic perspective, the antibacterial and antiplaque efficacy of Colgate Total dentifrice (CTD).METHODOLOGY:
A single-blind crossover study design utilized 11 healthy human subjects. After a one-week washout period, subjects donated dental plaque, received a dental prophylaxis, and subsequently brushed with a test product. Twenty-four hours postbrushing, dental plaque was collected and a clinical plaque score determined. Dental plaque was submitted for Real-time Polymerase Chain Reaction (Real-time PCR) analysis. The same procedure was repeated in accordance with a crossover design for the use of the second test product. Following a one-week washout, a plaque donation, prophylaxis, and brushing with the test product ensued for each subject. Twenty-four hours post-brushing, the subjects returned for a plaque score and plaque donation.RESULTS:
Twenty-four hours after brushing, dental plaque coverage increased 17.88% +/- 8.27% with CTD, compared to 30.42% +/- 9.97% with Colgate Cavity Protection (CCP; p = 0.005). Real-time PCR found plaque collected 24 hours after brushing with CTD exhibited, on average, fewer representative periodontal pathogens (Fusobacterium nucleatum, Actinobacillus actinomycetemcomitans, Tannerella forsythensis, and Porphyromonas gingivalis) and fewer early colonizers (Actinomyces naeslundii) than plaque collected before brushing, whereas CCP showed a moderate effect on oral bacteria.CONCLUSION:
The study provides clinical and molecular biological evidence to substantiate the antibacterial and plaque control benefits of Colgate Total, and suggests the value of combining a molecular biological method with clinical research to corroborate clinical benefits.
