Outline of Final Research Achievements

I studied a suppressant effect of root caries due to Toothplane coat materials based Nanoparticles Phosphate Silicate(kind of dental hypersensitivity restraint materials control hyperesthesia by forming an inorganic nanoparticle layer on the surface of the tooth),the formation of the stable nanoparticle layer was able to observed in the experiment in the trial pieces.I examined the making method of the trial piece closely to thought that the making of the trial piece has a problem, but an expected result was not provided.
A part of trial piece which a nanoparticle layer was formed was observed non-adhesion of the plaque(he biofilm which oral bacteria forms).
