Inclusion criteria

* Male or female volunteer 18 - 65 years of age (inclusive). * Good general health with a minimum of twenty (20) natural, uncrowned teeth (excluding third molars) * Able and willing to sign the informed consent form. * Plaque score of at least 1.5 on the modified Quigley-Hein plaque index. * No known history of allergy to personal care/consumer products or their ingredients, relevant to any ingredient in the test products as determined by the dental/medical professional monitoring the study

Exclusion criteria

* Medical condition which requires pre-medication prior to dental procedures/visits * Medical condition which precludes not eating/drinking for 2 hours * Advanced periodontal disease (gum disease) * 5 or more decayed, untreated dental sites (cavities) * Diseases of the soft or hard oral tissues * Orthodontic appliances * Abnormal salivary function * Use of drugs that can affect salivary flow * Use of antibiotics one (1) month prior to or during this study * Use of any over the counter medications other than analgesics (i.e. aspirin, ibuprofen, acetaminophen, naproxyn, etc) * Pregnant or breastfeeding. * Participation in another clinical study in the month preceding this study * Immune compromised individuals (HIV, AIDS, immuno suppressive drug therapy)

Design outcomes

MeasureTime frameDescription
Triclosan Concentration in Dental Plaque12 hoursTriclosan is analyzed by gas chromatography (GC) with Atomic Emission Detection (480 nm) and quantitated by determining the ration of the peak height of triclosan to the peak height of an internal standard and relating the result to corresponding ratios of calibration standards.

Recruitment details

subjects were recruited by the PI at the clinical site

Pre-assignment details

Subjects were screened for medical and oral health criteria and then began a 1 week washout period with fluoride toothpaste.

Triclosan Concentration in Dental Plaque

Triclosan is analyzed by gas chromatography (GC) with Atomic Emission Detection (480 nm) and quantitated by determining the ration of the peak height of triclosan to the peak height of an internal standard and relating the result to corresponding ratios of calibration standards.
