Dental erosion is the demineralization of the hard tooth substance caused by acids. Particularly in industrialized countries this is an increasing problem due to changes in drinking and eating habits in recent decades. Additionally, the teeth surface is eroded by mechanical interaction like brushing. To substantially reharden demineralized enamel, the development of appropriate prophylaxis and therapy is important. HMC presents two studies that tested toothpaste and mouth rinses containing chitosan.

In recent decades, there have been major advances in regenerative medicine, such as the treatment of severe nerve injuries. Implants used as scaffolds for nerve cell regeneration are often made of biodegradable polymers, such as chitosan. Below, we present a study that investigated the degradation and stability of tubular chitosan-based implants.
