Clinical effectiveness of a dentifrice containing triclosan and a copolymer for controlling breath odor.

Purpose: To investigate in a double-blind clinical study the effectiveness of a dentifrice containing triclosan and a copolymer (Colgate Total Toothpaste) for controlling breath odor 12 hours after brushing the teeth.

Methods: A panel of four expert judges using a nine-point hedonic scale evaluated breath odor. Following a baseline evaluation of breath odor, prospective study subjects who presented breath odor scores above the threshold value for unpleasant breath odor were stratified by score, and randomized into two treatment groups.

Comparative efficacy of a new battery-powered toothbrush and a commercially available manual toothbrush on the removal of established supragingival plaque: a single-use crossover study in adults.

Objective: The objective of this single-use, examiner-blind, two-treatment crossover clinical study was to evaluate the efficacy of a new battery-powered toothbrush (Colgate MicroSonic) relative to that of a currently marketed manual toothbrush (Oral-B Indicator) for the removal of supragingival plaque. This study included the assessment of plaque removal in the whole mouth, at the gumline, and at interproximal sites via the comparison of pre- and post-brushing plaque levels measured using the Rustogi Modification of the Modified Navy Plaque Index.

Methodology: Qualifying adult male and female subjects from the Newark, New Jersey area were provided with a commercially available toothbrush (Colgate Plus Toothbrush) and dentifrice (Colgate Cavity Protection Great Regular Flavor Fluoride Toothpaste) to use at home for three days before beginning the first phase of the crossover study.

Comparative tooth whitening and extrinsic tooth stain prevention efficacy of a new dentifrice and a commercially available tooth whitening dentifrice: six-week clinical trial.

Objective: The objective of this six-week, examiner-blind clinical study was to assess the tooth whitening and extrinsic stain prevention efficacy of a new dentifrice delivering 1.0% hydrogen peroxide, 0.243% sodium fluoride, and sodium tripolyphosphate in a high-cleaning silica base (Test Dentifrice) relative to that of a commercially available hexametaphosphate-containing whitening dentifrice (Positive Control Dentifrice).

Comparative tooth whitening and extrinsic tooth stain removal efficacy of two tooth whitening dentifrices: six-week clinical trial.

Objective: The objective of this six-week, examiner-blind clinical study was to assess the tooth whitening and extrinsic tooth stain removal efficacy of a new dentifrice delivering 1.0% hydrogen peroxide, 0.243% sodium fluoride, and sodium tripolyphosphate in a high-cleaning silica base (Test Dentifrice), relative to that of commercially available hexametaphosphate-containing whitening dentifrice (Positive Control Dentifrice).

A clinical investigation of the tooth whitening efficacy of a new hydrogen peroxide-containing dentifrice.

Objective: The objective of this four-week, double-blind clinical study was to assess the tooth whitening efficacy of a new dentifrice delivering 1.0% hydrogen peroxide, 0.243% sodium fluoride, and sodium tripolyphosphate in a high-cleaning silica base (Test Dentifrice), relative to that of a control dentifrice containing 0.
