Through extensive annual surveys and research on the worn areas of teeth, manufacturers are concerned about how to evaluate the degree of erosion of dental amalgam (filling) and how to reduce its degree of corrosion. To achieve their goal, they conducted wear tests imitating general oral dental fillings according to ISO standards such as ISO/TS 14569-1.

However, the mechanism of tooth wear involves the restoration of teeth in the oral cavity, which is very complex. Furthermore, these mechanisms may vary from person to person. The wear testing standards for dental amalgam and toothpaste include the use of toothbrushes and toothpaste. Usually, the reference material is rubbed back and forth with toothpaste to a certain amount, and then the degree of corrosion generated by this test can be monitored.

There are a large number of oral care products available to improve the appearance of teeth, such as filling creams, toothpaste, etc. Fillers need to have strong abrasion resistance, while toothpaste and whitening products need to limit the wear and tear they cause on teeth. Therefore, dental manufacturers are mainly interested in how to evaluate the degree of corrosion between teeth and filling amalgam (filling paste).

Taylor Hobson provides various measurement techniques for dental manufacturers and researchers to evaluate the degree of wear of teeth and fillings such as amalgam.
