Dentisse Passes Every Test
Dentisse® Natural Reflection™ was laboratory tested with a variety of toothpastes, including leading market and private-label brands. The tests evaluated stain removal, polish, and abrasiveness.
Conclusion? Few of the toothpastes live up to their advertising claims. Some may remove stains well but are too abrasive. Others are gentle but fail to clean in a way that most people find acceptable. And most brands polish poorly.
Dentisse is a quality toothpaste that does live up to its claims, providing excellent stain removal, high polish, and low abrasiveness.
Testing Procedures and Results
Dulled tooth enamel specimens (8 per toothpaste) were brushed with the toothpastes on a toothbrushing machine for a set number of strokes at uniform pressure with standard toothbrushes. A specialized instrument (gloss meter) was used to measure specular reflectance of the specimens before and after treatment. This method correlates directly with polish results observed in clinical trials.
Of the 26 commercially available toothpastes tested, Dentisse imparted the highest degree of polish, producing a score of 97 while the rest of the whitening/polishing toothpastes ranged from a low of 38 to a high of 80.
The Enamel Polish Test results were presented in April 2008 at the American Association for Dental Research (AADR) conference.
Stained (by means of coffee/tea solution for 2 weeks) tooth specimens (16 per toothpaste) were brushed with the toothpastes on a toothbrushing machine for a set number of strokes at uniform pressure with standard toothbrushes. A specialized instrument (spectrophotometer) was used to measure the stain color before and after treatment. This method correlates directly with clinical results and is widely accepted for determining the ability of toothpastes to remove stain and whiten teeth. Test results are reported as the Pellicle Cleaning Ratio (PCR).
Dentisse had the highest PCR score (136) of all the toothpastes tested - a remarkable achievement considering it was accomplished with low abrasiveness. The rest of the toothpastes had PCR scores that ranged from a low of 30 to a high of 130.
The Stain Removal Test results were presented in July 2008 at the International Association for Dental Research (IADR) conference.
Specially prepared tooth dentin specimens (8 per toothpaste) were brushed with toothpastes on a toothbrushing machine as described for the previous two tests. A sensitive instrument (scintillation counter) was used to determine the amount of dentin removed after treatment. Results are reported as the Relative Dentin Abrasion (RDA) score. The more dentin removed, the higher the RDA value.
Obviously, a low value is desired here, because the less dentin removed, the more gentle the toothpaste. Dentisse provided an RDA of 88, which is lower than the score for most toothpastes on the market, some of which tested as high as 200. As a general rule, any toothpaste with an RDA score under 100 is considered gentle and very safe for consumers to use.
The Abrasiveness Test results were presented in July 2008 at the International Association for Dental Research (IADR) conference.
