Dental plaque - not a problem with nanoparticles, experts say


Nanoparticles on the basis of oxide of hafnium change understanding about stomatology. They allow to deal trouble-free with a dental plaque, writes "News of Mail.RU". Developers have attached organosilanovy polymers and oligopeptida to a surface of nanoparticles. It allowed particles to join selectively bacteria in a raid.

If to apply particles on teeth, it is possible to see on the x-ray degree damage of teeth a bacterial plaque. It is known: several hours later after cleaning on the surface of teeth bacteria which gradually stick together in a steady film of a dental plaque accumulate. The most dangerous bacteria - Streptococcus mutans. They turn sucrose into the lactic acid dangerous to enamel. It is important to find these bacteria in time and to kill them, but without mentioning the general microflora.

As have shown researches, particles approximately for 30% increased contrast of pictures of teeth in comparison with iodinated contrast agents. And a covering of particles an organosilanovy cover and their connection with small peptide gave the chance to become attached selectively to bacteria. In addition, particles contact cellular membranes of bacteria and cause gradual dissolution of internal systems of their cages. As have shown tests, the bacterial activity of a dental plaque age in two days can be suppressed completely in 20 minutes.
