The design of toothpaste and toothbrushes is a time-consuming process involving the testing of various samples. A new type of application has nonetheless proved quite useful in addressing this concern; by incorporating salient parameters such as abrasive particle size, which can be modified with a single click to further enhance decision making in the above mentioned process.
Simulated tooth brushing
Researchers at the Fraunhofer Institute for Mechanics in Freiburg recently unveiled their methodology; meant to equip producers of dental hygiene items in determining the cleaning effectiveness of various features in a quick and economical manner. Unlike the real world experiments, these characteristics can be easily tweaked in simulation, whether it’s the size, shape, material or quantity of abrasive elements in toothpaste, or the elasticity of toothbrush bristles.
Risk of wear from abrasive particles
Abrasive particles serve as key components of toothpaste, because they mechanically get rid of plaque from the teeth. A good toothpaste however shouldn’t be excessively abrasive, since the continued friction over time can damage the enamel, which doesn’t regenerate.
