Scientists from Moscow State University of Science and Technology (NUST MISIS) and other Russian research institutions have developed a unique nanomaterial that can prevent the development of cavities and provide “permanent” protection against microbial damage when added to dental restoration materials.
Yakov Karashenkov, chief physician at Rosdent Dental Clinic and a participant in the research, described the innovation as a technological breakthrough in dentistry. This nanomaterial, which is an antibacterial additive, can be used not only in fillings but also in various dental materials to prolong the lifespan of implants. The clinic has been using it successfully since September 2016.
The research team, led by Georgy Vlalov, associate professor at Moscow State University of Science and Technology, investigated the properties of extremely small nanoparticles made of titanium, iron, zinc, and other metals. Their experiments revealed that these nanoparticles, much like antibiotics or enzymes in the body that fight microorganisms, can eliminate bacteria even at very low concentrations. Adding these nanoparticles to fillings and other dental materials addresses two common dental issues: the loss of fillings and the formation of cavities at the junctions between fillings and tooth tissue.
Scientists explained that even when all procedures are followed correctly, tiny gaps can develop around fillings where bacteria can thrive. Incorporating nanoparticles into fillings can effectively solve this problem permanently, as the nanoparticles kill microorganisms while remaining intact.
These nanoparticles are used not only in Rosdent clinics but also at the Kirov State Academy of Medical Sciences. Fillings created with this technology have been approved by the Russian Federal Service for Health Supervision and are now being used by some commercial dental companies.
