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(More)
Bacterial adhesion to oral hard materials is dependent on various factors, for example, surface roughness and surface composition. In this study, bacteria retention on three oral hard substrates, hydroxyapatite (HAP), enamel, and polished enamel (p-enamel) were investigated. The surface morphology and roughness of the three substrates were measured by(More)
PURPOSE To evaluate the clinical efficacy of a mouthwash containing 0.075% cetylpyridinium chloride (CPC) in a fluoride-free, alcohol-free base and a mouthwash containing essential oils in a fluoride-free, 21.6% alcohol base as compared to a fluoride-free, alcohol-free non-antibacterial mouthwash in controlling established dental plaque and gingivitis after(More)
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. Therefore, in vitro assessment is(More)
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(More)
PURPOSE To evaluate the efficacy of a test regimen (TR) integrating the use of a commercially available triclosan, PVM/MA copolymer, and sodium fluoride containing toothpaste, an alcohol-free, fluoride-free cetylpyridinium chloride (CPC) mouthwash, and a manual toothbrush with cheek and tongue cleaner compared to a negative control regimen (NCR) integrating(More)
A mechanical tooth brushing device coupled to an atmosphere pressure ionization ion trap mass spectrometer (API-IT-MS) combination has been developed to study the influence of time and dilution on aroma release from a model dentifrice system. API-IT-MS response to nine commonly used dentifrice flavor components was initially studied. Linear regression(More)
BACKGROUND AND OBJECTIVE Goal was to evaluate the potential of in vivo optical coherence tomography (OCT) imaging to determine the response of patients with xerostomia to a dry mouth toothpaste versus fluoride toothpaste placebo. STUDY DESIGN/MATERIALS AND METHODS Ten subjects with xerostomia participated in this double-blind, crossover,(More)
PURPOSE To evaluate the clinical efficacy of two commercially available, fluoride-free, alcohol-free mouthwashes containing either 0.075% or 0.07% cetylpyridinium chloride (CPC) in controlling established dental plaque and gingivitis compared to a non-antibacterial control mouthwash. METHODS A 6-week double-blind, randomized clinical trial was conducted(More)
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(More)
