The efficacy of a newly designed toothbrush to decrease tooth sensitivity.

Objective: The objective of this monadic clinical study was to evaluate the reduction in tooth sensitivity among patients who used the Colgate 360 degrees Sensitive toothbrush during an 8-week period.

Methodology: Adult men and women from the northern New Jersey area were required to present two teeth that exhibited sensitivity both to tactile stimulation using the Yeaple Probe and to thermal stimulation using an air blast delivered by a standard dental-unit syringe. After examination of the oral soft and hard tissues, qualifying patients were provided with a Colgate 360 degrees Sensitive toothbrush and a supply of a commercially available, nonsensitive fluoride toothpaste, and instructed to brush their teeth for 1 minute, twice daily (morning and evening), using only the toothbrush and dentifrice provided.

Clinical studies to assess the extrinsic stain prevention and stain removal efficacy of a variant of a commercially available dentifrice containing a new dual silica system.

Objective: The objective of these two six-week, double-blind clinical studies was to compare the extrinsic stain prevention (Study #1) and stain removal (Study #2) efficacy of a new dentifrice (Colgate Total Advanced Toothpaste) containing 0.3% triclosan/ 2.0% polyvinylmethyl ether/maleic acid (PVM/MA) copolymer/0.

A clinical investigation of the efficacy of a tooth-whitening gel.

The objective of this randomized, controlled, examiner-blind, parallel-group clinical study was to determine whether a tooth-whitening gel (Colgate Simply White Night Clear Whitening Gel) can significantly lighten teeth when used once daily at night, as compared with a commercially available dentifrice. Following a baseline tooth shade evaluation using the VITA Shade Guide, qualifying adult male and female subjects from the Buffalo, New York area were randomized into 2 treatment groups, which were balanced for baseline VITA Shade Guide scores, gender, and age. The treatment groups were: (1) a commercially available dentifrice only; and (2) a tooth-whitening gel in addition to a commercially available dentifrice.

Comparative clinical investigation of the tooth whitening efficacy of two tooth whitening gels.

Objective: The objective of this randomized, double-blind, parallel-group clinical study was to compare the tooth whitening efficacy of two tooth whitening gel products--Colgate Simply White Night Clear Whitening Gel containing either 25% carbamide peroxide, or 8.7% hydrogen peroxide--when used once daily at night.

Methodology: Following a baseline tooth shade evaluation using the Vita Shade Guide, qualifying adult male and female subjects from the Central New Jersey area were randomized into two treatment groups, which were balanced for baseline Vita Shade Guide scores, gender and age.

Efficacy of a novel, nontray, paint-on 18% carbamide peroxide whitening gel.

A double-blind, 3-week, randomized, placebo-controlled, parallel-group clinical trial was conducted to evaluate the tooth-whitening efficacy of a novel nontray, "paint-on" liquid whitening gel containing 18% carbamide peroxide (Colgate Simply White Clear Whitening Gel). Efficacy was based on measured Vita tooth-shade scores collected at baseline and after 2 and 3 weeks of product use. Eighty healthy volunteers were balanced into 2 groups based on gender, age, and shade scores (A3 or higher).

Comparative efficacy of two battery-powered toothbrushes on overnight plaque removal: a single-use clinical study in New Jersey.

Objective: The objective of this single-use, examiner-blind clinical study, was to evaluate the efficacy of a newly designed Colgate Actibrush (battery-powered toothbrush) relative to the Crest SpinBrush (battery-powered toothbrush) for the removal of supragingival plaque.

Methodology: This study included the assessment of plaque removal via the comparison of pre- and post-brushing plaque levels. A total of 80 adult male and female subjects from the central New Jersey area reported to the clinical facility for a baseline (pre-brushing) plaque examination after having refrained from all oral hygiene procedures and chewing gum for 24 hours, and from eating, drinking, or smoking for four hours.

Comparison of plaque removal efficacy of a battery-powered toothbrush and a manual toothbrush: a single-use clinical study in New Jersey.

Objective: This single-use, examiner-blind clinical study evaluated the efficacy of a newly introduced battery-powered toothbrush (Colgate Motion Toothbrush) relative to a manual toothbrush (Oral-B CrossAction toothbrush) for the removal of supragingival plaque.

Methodology: This study assessed plaque removal via the comparison of pre- and post-brushing plaque levels. A total of 126 adult male and female subjects from the northern New Jersey area reported to the clinical facility for a baseline (pre-brushing) plaque examination after having refrained from all oral hygiene procedures and chewing gum for 24 hours, and from eating, drinking or smoking for four hours.
