1、 Main purpose and working principle

ItypeAutomatic brushing evaluation testerMainly used for research, testing institutions, and manufacturers of oral cleaning and care products to evaluate the stain removal and whitening effects, as well as the removal of external color spots, of products such as toothbrushes, toothpaste, oral cleaning and care fluids, dental patches, tooth powders, electric toothbrushes, teeth whitening agents, grinding rods, denture cleaners, and other raw materials such as friction agents, moisturizers, thickeners, foaming agents, taste improvers, and fragrances. Its evaluation and measurement method imitates the mechanical process of human tooth brushing, and synchronously performs reciprocating brushing and grinding through mechanical transmission to control the testing unit, which is closer to the actual brushing conditions. The equipment consists of eight brushing and grinding units, which can work simultaneously under the same conditions, improving the accuracy of the experiment and increasing work efficiency.

2、 Structural description

This device has a desktop appearance and is suitable for placement on a workbench that is close to the actual operating height. Eight brushing and grinding units are arranged in parallel on the operating surface of the equipment, and the open working state facilitates the tester to observe the testing situation at any time. The main transmission structure and electrical components are located above the brushing and grinding unit for easy equipment cleaning. The operation screen and power switch are located in the upper right corner of the operation surface, which is overall beautiful and elegant. The frame is welded with structural square tubes, and the panels are made of thickened stainless steel, which is sturdy and durable.

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.
