Abstract

  • The paper considers the possibility of early noninvasive diagnosis of periodontal diseases by using the method of Raman spectroscopy. The results of spectral studies of tooth enamel with periodontitis by means of this method are shown. It is proposed to use the obtained data for early non-invasive diagnostics of periodontitis.
