The paper the study of new light-cured composite dental materials by atomic absorption spectroscopy are considered. High-quality aesthetics, durability, functionality and maximum preservation of hard dental tissues are the result of new adhesive preparation and improvement of the physico-chemical and optical properties of composites, therefore, the study of the optical properties of composites is relevant and promising. The article the objects under study, the appearance of the spectrophotometer, the optical scheme and the technical characteristics of the device are presented. In the study of restorative dental composites, different absorption capacity of materials was obtained. Maximum absorption in all composite materials in the wavelength range = 250…360 nm was detected.

spectrophotometer, absorption coefficient, composite, atomic absorption method, cuvette compartment, wavelength of light radiation.
