Abrasivity potential of dentifrices is assessed mostly in vitro due to practical, scientific, and ethical reasons. The two most used evaluation methods are based on the measurement of radioactive dentin release or dentin surface profile changes, after simulation of toothbrushing with dentifrices. The radiotracer method known as radioactive or relative dentin abrasivity (RDA) was developed decades ago and is the most frequently used today (the 'gold standard' for many). The RDA is a reasonably… CONTINUE READING
