Russian scientists, as part of an international group, have developed a new coating for tooth enamel. It mimics the natural structure of the tooth and suppresses the development of bacteria that cause caries. This was reported by the Russian Science Foundation (RSF). The results of the study are published in the journal Biomaterials Science.
Tooth enamel is constantly exposed to microorganisms, among which bacteria of the genus Streptococcus are particularly dangerous, contributing to the formation of plaque and damage to teeth. In modern dentistry, special coatings and fluoride-containing preparations are used to protect against destruction. However, they are not always reliable and are quickly washed away.
The new coating not only prevents plaque formation, but also strengthens enamel. In terms of microhardness, the material is only 10–20% inferior to natural enamel. Unlike traditional dental products, the new approach offers long-term protection and combines enamel restoration with a powerful antibacterial effect.
The chosen combination of materials allowed us to create a coating with high strength and antibacterial properties. In the future, we plan to focus on studying its durability in conditions close to real clinical practice, as well as its biocompatibility and effectiveness with prolonged use.
