On the professional holiday of dentists, we are sharing good news: for the first time in Russia and the CIS, a national standard (GOST) has been approved regulating the method for determining the abrasiveness of toothpastes. The standard is based on the RIA (Russian Abrasiveness Index) assessment method developed at RUDN University.
The development was developed by staff from the Institute of Digital Dentistry at the RUDN Medical Institute, together with scientists from the L.F. Vereshchagin Institute of High Pressure Physics of the Russian Academy of Sciences. The method has undergone a full cycle of scientific testing and will be implemented on June 1, 2026.
The following took part in the creation of the methodology and standard:
Samvel Vladislavovich Apresyan, MD, Professor, Honored Inventor of the Russian Federation, Director of the Institute of Digital Dentistry at the RUDN Medical Institute; Alexander Gennadievich Stepanov, MD, Professor, Honored Inventor of the Russian Federation, Professor of the Institute of Digital Dentistry at the RUDN Medical Institute; Svetlana Konstantinovna Matelo, MD, Professor of the Institute of Digital Dentistry at the RUDN Medical Institute; Alexey Serverovich Useinov, PhD in Physics and Mathematics, Deputy Director for Research at the L.F. Vereshchagin Institute of High Pressure Physics of the Russian Academy of Sciences.
What is the scientific novelty?
The new GOST is based on an objective instrumental approach and includes:
The use of a rotary friction machine simulating the toothbrushing process; the application of contactless 3D optical profilometry; quantitative assessment of the wear depth of the model material; and the calculation of the Russian Abrasiveness Index (RAI) with a clearly defined scale of values.
Unlike foreign methods (including the RDA method), the new standard ensures reproducibility, high accuracy, and adaptation to the Russian standardization system, and also takes into account modern digital methods of surface analysis.
The adoption of the new GOST standard creates a unified national approach to assessing the safety and efficacy of toothpastes and improves the quality control of perfumes and cosmetics. It also simplifies the evaluation and certification of domestic and imported oral hygiene products, promoting consumer protection and the development of evidence-based dentistry.
The development of the first national standard for assessing the abrasiveness of toothpastes confirms the leading role of RUDN University and the Institute of Digital Dentistry at the Medical Institute in developing the scientific and technological foundations of modern dentistry and conducting interdisciplinary research at the intersection of medicine, physics, and digital technology.
