Abstract. The method of fluorescence spectroscopy is considered as a high-precision and informative tool for measuring the optical properties of biological and synthetic objects. An automated luminescence spectrometer SDL-2 for determining the fluorescence spectra of the materials under study is presented. The fluorescence spectra of 50 samples of composite materials of hard tissues of teeth of 50 patients of different age groups are obtained. Optical characteristics of the enamel-dentin junction, dentin and enamel are investigated. According to the results of comparative analysis of filling materials, it is revealed that the composites "Estelite Asteria A2B" and "Estelite Asteria OcE" are superior in optical properties to other materials. Recommendations for the use of each material separately are given.
Keywords: fluorescence spectroscopy, intensity, therapeutic dentistry, aesthetics, composite material, teeth, wavelength
