Missouri Analytical is the only independent testing laboratory in the world to offer to the dentifrice industry Radioactive Dentin Abrasivity (RDA) and Radioactive Enamel Abrasivity (REA) assays. For over 35 years, valuable abrasivity information has been provided to over fifty clients in more than a dozen countries.
A quality control program for existing products can be economically implemented. Our inexpensive, short-term in-vitro tests can eliminate more expensive, time-consuming in-vivo studies. Such a program serves as a useful tool for maintaining abrasivity specifications. We offer both the Grabenstetter and Hefferren methods of abrasivity testing. As an independent laboratory, we pride ourselves on delivering test results promptly and accurately.
We would be glad to provide additional information about the abrasivity study. Please contact us for further details.
