PURPOSE To evaluate the extrinsic stain profiles of two experimental stannous-containing dentifrice prototypes compared to two marketed control dentifrices. METHODS This was a 5-week, randomized, four-treatment, parallel group, double-blind clinical trial of healthy adults. Following a baseline Lobene Stain Index evaluation, subjects received a prophylaxis limited to the 12 anterior teeth to ...

Brushing is the most common cleansing method employed on complete dentures and it may damage the integrity of acrylic resin, the main component of this type of prosthesis. This study evaluated the abrasion resistance of artificial teeth with different number of acrylic layers, and the abrasiveness of specific and non-specific dentifrices for denture cleaning. The abrasion test was conducted by ...

OBJECTIVE To determine the ability of various marketed dentifrices containing stabilized stannous fluoride (SnF2), sodium fluoride (NaF), or sodium monofluorophosphate (SMFP) to protect enamel against the earliest stages of erosive dietary acid damage using an in vitro enamel protection model. METHODS Acid-challenged, extracted human teeth were treated with a 1:3 dilution of dentifrice, rinse...

BACKGROUND Different formulations of dentifrices exist in the market. Usually, single toothpaste is used by all family members including children. There is a big concern of fluoride ingestion with the toothpaste containing high fluoride content in children. Recently, new toothpaste (including toothpaste) with remineralization potential without fluoride content has been formulated. AIM There i...

The minimum requirement for the anti-caries effect of a dentifrice is the presence of available and stable fluoride in the formulation. The concentration of available fluoride in the major dentifrices sold in Brazil has been reported, but few data have been published about its stability, which is temperature-dependent. Thus, the aim of this study was to evaluate the concentration and stability ...

The aim of this study was to evaluate the effect using dentifrices containing tricalcium phosphate (β-TCP) on microhardness, enamel color, and topography before bleaching treatment with 35% hydrogen peroxide (HP). Fifty bovine incisor enamel/dentin blocks (4 × 4 2 mm) were randomized into five groups (n=10): (C) negative control (no treatment), positive (35% HP), Colgate Total 12 then HP (CT + ...

OBJECTIVES The provision of antiplaque benefits to dentifrices assists patients in improving hygiene and reducing susceptibility to gingivitis and caries. Chemical plaque control involves different mechanisms and is mostly associated with antibacterial effects, but also includes effects on pellicle surface chemistry to improve cleansing or discourage renewed plaque formation. It is the aim of t...

In order to compare the antiplaque and antigingivitis activity of three commercially-available triclosan containing dentifrices with that of a placebo dentifrice without triclosan, a double-blind clinical study was conducted on 194 subjects over six months. Following baseline supragingival plaque and gingivitis examinations and a complete oral prophylaxis, subjects were stratified by their whol...
