- Q2126406 abstract "Relative dentin abrasivity (RDA) is a method for measuring the abrasive effect that the components of the toothpaste have on the tooth, particularly on enamel and dentin. It involves using standardized abrasives compared against the test sample.The determination of this value is done by determining the activity while cleaning worn dentin which is radioactively marked by mild neutron irradiation. The values obtained depend on the size, quantity and surface structure of abrasive used in toothpastes.Since 1998, the RDA value is set by the standards DIN EN ISO 11609.Currently, the claim on products such as toothpaste are not regulated by law.The procedure was later adopted by ADA for measuring of Relative Dentin Abrasion Index. According to the ISO standard, every toothpaste with an RDA under 250 is safe for a lifetime of use.".
