ABSTRACT

It is the first time the phenomenon of luminescence of tooth hard tissues, in particular, dentine, under the electron beam influence in vacuum has been discovered. It has been shown that the most probable reason of the observed radiation is cathode luminescence of the crystals of tooth hard tissues, and described the most obvious mechanisms of its generation. Change in luminescence color, depending on the place of primary electrons hits, which can be explained by different chemical element compositions of compounds and complexes that are the sources of the observed luminescence, has been discovered.
