Triclosan blocks MMP-13 expression in hormone-stimulated osteoblasts.

Background: Matrix metalloproteinase-13 (MMP-13) is an important enzyme for the modulation of bone turnover and gingival recession. Elevated levels of MMP-13 are associated with alveolar bone resorption, periodontal ligament breakdown, and gingival attachment loss, which are the clinical symptoms of periodontal disease. Evidence continues to suggest that periodontal disease contributes to oral tissue breakdown and is linked to numerous systemic conditions.

Reduction of VSC and salivary bacteria by a multibenefit mouthrinse.

To evaluate the effectiveness of a multibenefit mouthrinse containing 0.05% cetylpyridinium chloride (CPC) and 0.025% sodium fluoride in reducing volatile sulfur compound (VSC) levels and total cultivable salivary bacteria, at both 4 h and overnight.

Clinical comparison of a new manual toothbrush on breath volatile sulfur compounds.

The objective of this randomized, crossover study was to compare the effectiveness of a newly designed manual toothbrush (Colgate 360 degrees) to two commercially available manual toothbrushes (Oral-B Indicator and Oral-B CrossAction) and a battery-powered toothbrush (Crest SpinBrush PRO) for their ability to reduce overnight volatile sulfur compounds (VSC) associated with oral malodor. The study followed a four-period crossover design. Following a washout period, prospective subjects arrived at the testing facility without eating, drinking, or performing oral hygiene for baseline evaluation of breath VSC levels.

Clinical comparison of a new manual toothbrush on the level of hydrogen-sulfide-forming bacteria on the tongue.

The objective of this randomized, crossover study was to compare the effectiveness of a newly designed manual toothbrush (Colgate 360 degrees) to two commercially available manual toothbrushes (Oral-B Indicator and Oral-B CrossAction) and a battery-powered toothbrush (Crest SpinBrush PRO) for their ability to reduce hydrogen-sulfide-forming bacteria on the tongue. After a washout period, subjects arrived at the clinical site for baseline sampling without performing dental hygiene, eating, or drinking. Subjects sampled the left side of their tongue with a cotton swab.

Clinical efficacy of Colgate 360 degrees and three commercially available toothbrushes on the removal of desquamated epithelial cells.

A clinical study was done to evaluate the performance of four toothbrushes on the removal of desquamated epithelial cells after brushing according to the manufacturers' instructions for use. This randomized, crossover-design clinical study compared a new manual toothbrush (Colgate 360 degrees) to two commercially available manual toothbrushes (Oral-B CrossAction and Oral-B Indicator) and a commercially available battery-powered toothbrush (Crest SpinBrush PRO). Adult men and women subjects reported to the clinical facility after a 1-week "washout" period of brushing with a regular fluoride dentifrice and a soft-bristled toothbrush.

Driving toothbrush innovation through a cross-functional development team.

A cross-functional team was assembled to take on the project of developing a toothbrush that could deliver a "whole mouth clean." As such, this brush needed to not only demonstrate superior plaque removal from teeth, it also needed to provide a means for safe cleaning of soft oral tissues. During use, the brush needed to be comfortable both in hand and in mouth, and it required contemporary esthetics to help drive consumer acceptance.

Clinical efficacy of a triclosan/copolymer/NaF dentifrice and a commercially available breath-freshening dentifrice on hydrogen sulfide-forming bacteria.

Objective: The objective of this randomized, cross-over clinical study was to compare the 4-h and overnight effects of a triclosan/copolymer/fluoride (TCF-AF) dentifrice and a commercially available breath freshening (CBF) dentifrice containing fluoride for their ability to control H(2)S-forming bacteria.

Methods: Following a 1 week washout period of brushing with a regular fluoride dentifrice, subjects reported to the clinical site without performing oral hygiene, eating or drinking in preparation for baseline saliva sampling. After providing a baseline saliva sample, subjects were randomly assigned a test dentifrice and instructed to brush their teeth for 1 min, twice a day for 1 week.

Effect of a triclosan/PVM/MA copolymer/fluoride dentifrice on volatile sulfur compounds in vitro.

Objective: The objective of the investigation was to document the in vitro efficacy of a triclosan/PVM/MA copolymer/fluoride (TCF) dentifrice against the formation of volatile sulfur compounds (VSC) as well as the growth of H2S-producing bacteria. Clinical studies using organoleptic judges, gas chromatography, or a portable sulfide monitor have generally been employed in the assessment of treatments for the control of oral malodor. However, these studies are not appropriate for screening purposes because of the expense and time required.

Clinical comparison of Colgate Total Advanced Fresh vs a commercially available fluoride breath-freshening toothpaste in reducing breath odor overnight: a multiple-use study.

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.

Breath-odor evaluation by detection of volatile sulfur compounds--correlation with organoleptic odor ratings.

Volatile sulfur compounds are known to be major contributors to oral malodor, and their detection by gas chromatography (GC) is a commonly used method for evaluating breath odor in clinical trials. A custom-designed breath-sampling GC system was developed for this purpose. A clinical study was performed to compare the performance of this instrumental method to organoleptic evaluation by trained odor judges.

Clinical efficacy of Colgate Total Advanced Fresh and a commercially available breath-freshening dentifrice in reducing mouth-odor-causing bacteria.

The objective of this double-blind clinical study was to compare the long-lasting overnight (10- to 12-hour) and 4-hour effects of Colgate Total Advanced Fresh toothpaste to a commercial fluoridated breath-freshening dentifrice in controlling the level of mouth-odor-causing bacteria. Thirty-two adult men and women from New Jersey participated in the randomized, crossover design clinical study. After a 1-week "washout" period of brushing with a regular fluoride dentifrice, subjects refrained from dental hygiene, eating, and drinking in preparation for the morning visit.

In vitro efficacy of Colgate Total advanced fresh.

Generally, clinical studies using organoleptic judges, gas chromatography, or a sulfide monitor have been employed in the assessment of treatments for the control of oral malodor. However, these studies can be expensive and time consuming. Also, for agents whose safety has not been proven, these methods are not appropriate.

The technology behind Colgate Total Advanced Fresh.

In the early 1990s, a breakthrough toothpaste, Colgate Total, was launched with documented long-lasting activity against plaque, gingivitis, calculus, tooth decay, and bad breath. The technology behind this toothpaste is the combination of triclosan, a polyvinylmethylether/maleic acid copolymer, and sodium fluoride. The copolymer ensures maximal oral retention and subsequent release of the antibacterial triclosan.
