Nanoparticles protect teeth from cavities
December 23rd, 2008 Posted in Nanomedicine News
Researchers at the Clarkson University have developed a new technique of protecting teeth from cavities by polishing them with silica nanoparticles.
Professor Igor Sokolov and graduate student Ravi M. Gaikwad have used the technology used in the semiconductor industry to polish the human teeth down to nanoscale roughness. They proved that teeth polished like this become “too slippery” for the “bad” bacteria which ruin the tooth’s external layer.
Silica particles have been used previously for teeth polishing, but using nanoparticles in this area wasn’t reported before.
