Abstract

The relevance of the method of reflection spectroscopy for the study of modern dental restoration materials is demonstrated. An automated spectral device "Fluorat-02-panorama" with a developed optical attachment for measuring the reflection spectra of the studied samples is presented. Spectral dependences of the reflection coefficient of composite materials "Estelite Asteria" in “enamel” and “body” shades were obtained, and reflection spectra for samples of both genuine and fake materials were measured. It is shown that for a fake material, the spectral reflection curves are deformed, the maximum values of the reflection coefficient are shifted to the long-wave region of the spectrum, and there is also a significant decrease in the value of the reflection coefficient in the wavelength range of 380...780 nm.
