Analysis of the impact of toothpaste with detonation nanodiamonds of different concentrations on the enamel of human teeth

Abstract

Was to evaluate the abrasive effect of toothpaste with detonation nanodiamonds synthesis of various concentrations on the enamel of human teeth. The analysis of micrographs obtained by scanning electron microscopy showed a different abrasive and polishing effect of nanodiamonds in all the observed anatomical zones on the vestibular surface of the enamel of human teeth. No negative effect of the paste containing nanodiamonds on the enamel of human teeth was noted. At all concentrations of pastes containing nanodiamonds, on the vestibular surface of the enamel of the studied teeth, depot areas of densely attached particles of nanodiamonds were formed, a tendency was observed towards the formation of depots. The enamel of human teeth was mostly influenced by the concentration of nanodiamonds (2%, 2.5%). On the surface of the enamel were formed not only a depot of single nanodiamonds, but also accumulations were noted, merging into a layer in the form of a protective film. The study showed that toothpastes with nanoalases can reduce the enamel porosity, form a protective film on its surface, and thereby increase its microhardness and increase caries resistance.
