4 Principles

A brush grinding instrument with full controllable brushing load is used as a brush grinding instrument, a toothbrush and a polymethyl methacrylate (PMMA) grinding block The toothpaste samples were tested in vitro as test materials to replace teeth under certain brushing speed and brushing load conditions. After the brushing test, the surface roughness Ra of PMMA grinding blocks was measured with a surface roughness meter. The Ra values of 8 PMMA grinding blocks after the brushing test were The average value of the values was used to evaluate the abrasiveness of the toothpaste sample on the PMMA abrasive block.
