The purpose of this talk is to provide a condensed historical account of clinical and technical research on dentifrice abrasivity, which culminated in the methods we use and standards we apply for today’s commercial dentifrices. It is hoped that this information will help researchers to not only recognize and appreciate the sound, scientific basis for current models, but also to help them remember a few key concepts that remain relevant to the continued evolution of dentifrice abrasion models.
- Review the science used to determine the current abrasive limit of RDA 250
- Reaffirm the current FDA abrasive limits
- Review practical dental applications

Samuel St. John
Samuel St. John graduated in 2003 with a degree in Chemical Engineering from Clarkson University and went to work at The Procter & Gamble Company following two internships there. In 2008, he went back to graduate school at the University of Cincinnati where he graduated with a PhD in Chemical Engineering. Following his PhD work, Sam was a post-doctoral researcher at the University of Tennessee in Tom Zawodzinski’s lab. His research focused on electrochemical oxidation reactions and inorganic synthesis of nano-structures characterized using high-energy particle scattering.
Samuel rejoined P&G Oral Care R&D in 2016 to continue his work on understanding the etiology of oral diseases. He is interested in the invention and development of new-to-the-world oral care ingredients for the prevention and treatment of dental caries, erosion, and tartar formation, as well as breakthrough products for the treatment of gingivitis.
