Clinical evaluation of the efficacy of an in-office desensitizing paste containing 8% arginine and calcium carbonate in providing instant and lasting relief of dentin hypersensitivity.

Purpose: To determine the efficacy of an in-office desensitizing paste containing 8% arginine and calcium carbonate relative to that of a commercially-available pumice prophylaxis paste in reducing dentin hypersensitivity instantly after a single application following a dental scaling procedure and to establish the duration of sensitivity relief over a period of 4 weeks and 12 weeks.

Methods: This was a single-center, parallel group, double-blind, stratified clinical study conducted in San Francisco, California, USA. Qualifying adult male and female subjects who presented two hypersensitive teeth with a tactile hypersensitivity score (Yeaple Probe) between 10-50 grams of force and an air blast hypersensitivity score of 2 or 3 (Schiff Cold Air Sensitivity Scale) were stratified according to their baseline hypersensitivity scores and randomly assigned within strata to one of two treatment groups: (1) A Test Paste, a desensitizing paste containing 8% arginine and calcium carbonate (Colgate-Palmolive Co); and (2) A Control Paste, Nupro pumice prophylaxis paste (Dentsply Professional).

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.

A clinical investigation of the efficacy of two dentifrices for the reduction of supragingival calculus formation.

Objective: The objective of this double-blind clinical study, conducted in harmony with Volpe-Manhold design for studies of dental calculus, was to compare the efficacy of a dentifrice containing 0.3% triclosan/2.0% polyvinylmethyl ether/maleic acid (PVM/MA) copolymer/0.

Anticalculus effect of a cetylpyridinium chloride/zinc gluconate mucoadhesive gel: results of a randomized, double-blind, controlled clinical trial.

Objective: This randomized, double-blind, controlled clinical trial investigated the anticalculus effect of a cetylpyridinium chloride/ zinc gluconate (CPC/ZG) mucoadhesive gel.

Methodology: The 80 adults from the San Francisco area who fulfilled the enrollment criteria were stratified based on total Volpe-Manhold Index (VMI) scores (low, medium, or high), gender, and other demographic data. Within these strata, they were randomly assigned to the CPC/ZG gel group or the placebo gel group, and underwent a baseline oral soft tissue (OST) examination.

An anticalculus dentifrice with sodium hexametaphosphate and stannous fluoride: a six-month study of efficacy.

Aim: To compare the anticalculus efficacy of an experimental dentifrice (0.454% stabilized stannous fluoride/sodium hexametaphosphate) with a negative control.

Methods And Materials: This was a randomized, examiner-blind, parallel group study.

A clinical investigation of the efficacy of three different treatment regimens for the control of plaque and gingivitis.

Objective: The objective of this examiner-blind clinical study was to investigate the efficacy of three oral hygiene regimens for the control of gingivitis and supragingival plaque.

Methodology: Following a baseline examination for gingivitis and supragingival plaque, qualifying adult male and female subjects from the San Francisco, California area were stratified into three treatment groups, which were balanced for plaque. The groups were then randomly assigned to one of three oral hygiene regimens: 1) twice-daily tooth brushing with Colgate Total Toothpaste, accompanied by once-daily flossing after brushing; 2) twice-daily tooth brushing with Colgate Total Toothpaste without flossing; and 3) twice-daily tooth brushing with a sodium fluoride toothpaste, accompanied by once-daily flossing after brushing.

Desensitizing effect of a stabilized stannous fluoride/Sodium hexametaphosphate dentifrice.

Stannous fluoride (0.4%) has been incorporated into oral hygiene products to reduce dentinal hypersensitivity since the 1960s. The present study was designed to assess the desensitizing efficacy of a stabilized 0.

Anticalculus efficacy and safety of a stabilized stannous fluoride/sodium hexametaphosphate dentifrice.

The purpose of this study was to assess the anticalculus efficacy and long-term safety of a new stannous fluoride dentifrice containing sodium hexametaphosphate. This trial was a randomized, double-blind, parallel-group, 6-month study where, after a prophylaxis, subjects brushed twice daily with either a stabilized 0.454% stannous fluoride/13% sodium hexametaphosphate dentifrice (Crest Pro-Health) or a marketed multibenefit triclosan/copolymer control dentifrice.

Efficacy and safety of a novel stabilized stannous fluoride and sodium hexametaphosphate dentifrice for dentinal hypersensitivity.

Purpose: Dentinal hypersensitivity is a common complaint among dental patients. Recently, a novel 0.454% stabilized stannous fluoride dentifrice containing sodium hexametaphosphate (SHMP) was introduced that offers a desensitizing benefit.

An in vivo evaluation of the diagnostic quality ultra-speed versus insight intraoral dental film.

Twelve sets of FMS (full mouth survey) radiographs were taken by California licensed radiology technicians. Ten of the sets of FMS radiographs were taken using Ultra-Speed "D" film on the left side of the patient and Insight "F" speed film on the right side of the patient. The remaining two sets of films were taken using Insight Film on both sides of the patient to act as a control.
