PURPOSE Recently, sodium hexametaphosphate has been introduced in dentifrice formulations to aid in the control of extrinsic stain. Two independent studies were conducted to evaluate the stain removal efficacy of a novel 0.454% stannous fluoride and sodium hexametaphosphate dentifrice (Crest Pro-Health) relative to a positive control whitening dentifrice (Colgate Total + Whitening) over a 2-wee...

presence of available and stable fluoride in a dentifrice formulation is a major requirement for an anti-caries effect. although the available fluoride concentration in iranian dentifrices has been reported in previous studies, there is little information on its stability; which is dependent upon dentifrice formulation. this study was done to assess the fluoride ion concentration and stability ...

A major drawback to clinicians prescribing and patients using chlorhexidine rinse is the development of extrinsic staining. In order to assess the effectiveness of a whitening dentifrice in controlling chlorhexidine stain, fifty-seven subjects rinsed with chlorhexidine twice daily while brushing twice daily with either fluoridated whitening or a fluoridated regular dentifrice. Stain was assesse...

The aims of the study were (1) to compare the anticaries efficacy of a silica abrasive dentifrice containing 0.24% NaF and 0.3% triclosan/2.0% copolymer with a similar dentifrice without the triclosan/copolymer and (2) to study any disturbance of the oral mucosa associated with the test formulation. A double-blind, random, unsupervised, 30-month longitudinal clinical trial was conducted on 3,46...

Since the anticaries effect of a dentifrice with low fluoride concentration and low pH is unknown, the aim of the present study was to evaluate in situ the enamel remineralizing ability of this type of formulation. A double-blind crossover design employing 3 phases of 45 days was conducted. Six adult volunteers wore palatal devices containing 6 previously demineralized human dental enamel slabs...

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 ...

BACKGROUND Goal of this in vivo prospective, randomized, controlled, double-blinded, cross over study was to compare the level of plaque control and gingivitis after use of a novel dental gel (test) vs. A Triclosan/copolymer dentifrice (control). METHODS After coronal polishing, 22 subjects with moderate gingivitis were randomly assigned to brush twice daily with test or control dentifrice fo...

This study aimed to evaluate the effects of a flavor-containing dentifrice on the formation of volatile sulphur compounds (VSCs) in morning bad breath. A two-step, blinded, crossover, randomized study was carried out in 50 dental students with a healthy periodontium divided into two experimental groups: flavor-containing dentifrice (test) and non-flavor-containing dentifrice (control). The volu...

PURPOSE Routine toothbrushing is the principal method by which individuals remove plaque and control plaque-related diseases, such as periodontitis and caries. Oral health care professionals generally recommend at least 2 minutes brushing with an appropriate technique, and yet the average brushing time in the general population is closer to 45 seconds. Our understanding of the relationship betw...
