Researchers test the abrasiveness of toothpaste

Researchers test the abrasiveness of toothpaste  

There are many toothpastes available on the market that promote good dental health. Toothpaste is an important tool in the fight against tooth decay, which is why it's important for individuals to brush regularly. However, how can people be sure that the particular paste they are using is effective? Recently, researchers from the Fraunhofer Institute for Mechanics of Materials announced that they have developed a system for determining how effective the abrasives are in toothpaste. Abrasives are particles in toothpaste that work to clean the teeth 

When it comes to toothpaste, it's important for it to be abrasive enough to clean plaque on the teeth, but gentle enough to protect enamel. This is what the researchers have set out to test. They used highly sensitive materials to measure the depths of marks left by toothpaste on teeth, in a way that is more effective than the current method. 

"Our new approach enables us to determine realistic abrasion rates and characterize the interaction between brush, enamel and toothpaste. What’s more, our tests are less laborious than the time-intensive radiotracer procedures carried out by only a handful of laboratories worldwide," said researcher Andreas Kiesow, Ph.D.

These findings will hopefully lead to a system of creating more effective toothpastes that keep teeth healthy without damaging enamel.
