ABSTRACT

Penetration of nanoparticles into the tooth tissues is of significant interest in solving the problems, related to the reduction of the tooth sensitivity, enamel strengthening and restoration and cosmetic bleaching. In this work we demonstrate the possibility to use two-photon autofluorescence and second-harmonic generation microscopy for visualization of penetration of nanoparticles into the tooth tissues.
