Brush grinding tester

Brush grinding tester

1、 Main purpose

Since the birth of toothpaste, cleaning teeth has always been the most important and basic function of toothpaste, and the cleaning effect of teeth is mostly achieved through the friction agent in the toothpaste formula. The commonly used friction agents in toothpaste formulations currently include silicon dioxide, calcium carbonate, etc. The mass fraction of friction agent in toothpaste formula is usually15%～50%The friction agent in toothpaste is the main factor in mechanically removing dental plaque and stains during brushing. If toothpaste with high friction is used, it will cause wear on the hard tissues of teeth while cleaning them.

ISO11609In the method, bovine tooth samples were used as in vitro experimental materials in a brush grinder/The teeth are repeatedly brushed and ground on a toothbrush to evaluate the degree of wear and tear caused by toothpaste on the teeth.

We have developed multiple testing and evaluation instruments for toothpaste, toothbrush, tooth powder, and tooth whitening agents to assess tooth wear. Based on this, we have also developed multiple tooth grinding blocks for characterizing tooth wear.
