Tribological study of oral care Silica

Abstract : This study focuses on the effect of mechanical parameters for a better understanding of oral care silica tribological behavior. Reciprocating motion tests were performed with variable parameters (tooth- brushes design, load, brushing speed, with and without silica slurries). The analysis of the tests is based on the third body concept.The flows of third body were evaluated in-situ and post-mortem related to the evolution of the friction coefficient. Clues to understand the mechanisms involved are given, showing the multi-scales and multi-physical aspects of the problem.
