OBJECTIVE The primary purpose of this randomized, controlled, six-week clinical trial was to determine the effectiveness and safety of a new whitening dentifrice in removing extrinsic tooth stain and whitening teeth. An additional two-week exploratory study was conducted to determine whether the whitening or stain-prevention activity of the dentifrice would persist following cessation of use. ...

OBJECTIVE The primary aim of this study was to compare the in vivo efficacy and safety of dentifrices containing either 5% NovaMin or 5% potassium nitrate, and a non-desensitizing dentifrice, on dentin hypersensitivity in a four-week, double-blind clinical study among a population in south India. In addition, a companion scanning electron microscopy evaluation was performed to demonstrate wheth...

In order to endow environmental protection features to dentifrice, hydroxyapatite (HA) was added to ordinary dentifrice. The effects on dentinal tubule occlusion and surface mineralization were compared after brushing dentine discs with dentifrice with or without HA. The two types of dentifrice were then added to 100 µg/ml of hexavalent chromium cation (Cr(6+)) solution in order to evaluate the...

OBJECTIVE To compare the efficacy ofa dentifrice containing 0.3% triclosan, 2.0% PVM/MA copolymer, and 0.243% sodium fluoride in controlling established gingivitis and supragingival plaque to that of a commercially available dentifrice containing 0.454% stannous fluoride, sodium hexametaphosphate, and zinc lactate, and a commercially available dentifrice containing 0.243% sodium fluoride. MET...

PURPOSE This study was performed to assess the actual amount of dentifrice used and ingested and factors associated with use/ingestion among 28 U.S. preschoolers aged 40 to 48 months. METHODS Using their regular dentifrice brands/flavors and small child-sized toothbrushes (Oral -B 5), the participants or their parents placed dentifrice on toothbrushes three times to assess the quantity used a...

AIM To compare the plaque inhibition efficacy of a sodium fluoride/potassium nitrate (NaF/KNO3 with 1450 ppm F) test dentifrice to a 0.454% stannous fluoride/sodium hexametaphosphate/sodium fluoride positive control dentifrice (SnF2/SHMP with 1450 ppm F). METHODS AND MATERIALS Twenty-five subjects were randomized to a two-period, two-treatment, double blind crossover sequence using NaF/KNO3 (...

One hundred forty pregnant women 3 months gestation were enrolled in a 9 month, double-blind clinical study to evaluate the effect of 0.3% triclosan/copolymer dentifrice on gingivitis, compared to a placebo dentifrice. Women were stratified into two balanced groups according to their baseline gingivitis scores. They then received oral prophylaxis and were assigned to use either a placebo or the...

A six-months, double-blind, parallel, clinical study was conducted to evaluate the efficacy of an essential oil containing dentifrice on established plaque and gingivitis compared with a placebo dentifrice. A total of 104 subjects were stratified into two groups according to baseline Quigley-Hein Plaque Index scores and Loe-Silness Gingival Index scores. Each group was randomly assigned to use ...

The early use of fluoride dentifrice and use of larger quantities recently have been identified as risk factors for dental fluorosis. However, little is known about fluoride dentifrice use and ingestion among infants and young children whose developing permanent teeth are at risk for dental fluorosis. This paper reports on patterns of fluoride dentifrice use among a birth cohort up to 12 months...

OBJECTIVE To assess the efficacy ofa dentifrice containing 0.3% triclosan/2.0% PVM/MA copolymer/0.243% sodium fluoride for controlling established gingivitis and supragingival plaque relative to that of a dentifrice containing 0.454% stannous fluoride, sodium hexametaphosphate, and zinc lactate, and a dentifrice containing 0.243% sodium fluoride as a negative control. METHODS Following a base...
