Abstract

Penetration of nanoparticles into tooth tissues is of significant interest in solving problems related to reduction of tooth sensitivity, enamel strengthening and restoration and cosmetic bleaching. In this work we demonstrate two-photonexcited autofluorescence and second-harmonic generation microscopy for visualization of penetration of TiO₂ and ZnO nanoparticles into tooth tissues.
