Toothbrush evaluation tester, dental module brushing and grinding device

1、 The main purpose and working principle of the dental module brush grinder

The dental module brush grinder is mainly 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 stickers, tooth powders, electric toothbrushes, tooth whitening agents, grinding rods, active tooth 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.

The tooth module brushing and grinding instrument and tooth module staining instrument are designed and developed in accordance with the requirements of T/COCIA7-2020, GB/T43576-2023 Toothpaste Efficacy Evaluation and Removal of Exogenous Stains Laboratory Evaluation, and GB/T35832-2018 Toothpaste Friction Value Testing Method.

The pressure values of the dental module brush grinder are individually adjusted, and the working pressure values can be monitored in real time during experimental testing, greatly improving the accuracy and reliability of the testing. The dental module brushing and grinding instrument adopts an 8-bit independent pressure sensing module, and each independent module can be measured and calibrated to eliminate uneven pressure caused by mechanical manufacturing, workpiece installation, dental module preparation and processing. The dynamic pressure of the dental module brushing and grinding instrument is ≤ 30gf (this value can be measured and calibrated, which is better than the requirements of relevant standards). The dental module brushing and grinding instrument uses 8 independent test solution sample cups to avoid cross flow contamination of the test samples, which affects the accuracy of the experiment. Each test solution sample cup is easy to disassemble and assemble, and is convenient for cleaning and washing after the experiment is completed. It avoids long-term accumulation of cleaning residue on the equipment and testing environment due to experimental testing.

2、 Structural description

The dental module brush grinder has a desktop shape 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, making equipment operation simple and intuitive, and the sample area easy to clean. The operation screen and power switch are located above the operation, 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 agents in toothpaste formulations is usually 15% to 50%. Friction agents in toothpaste are 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.

Using bovine tooth samples as in vitro experiments in ISO11609 methodMaterial, on the brush grinder/toothbrushPerform reciprocating brushing and grinding on teeth to evaluate the degree of wear and tear of toothpaste on 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.
