Abstract
Results of a study on the use of absorption spectral analysis of light-curing radiopaque materials „Omichrome“ to evaluate their optical properties are presented. Application of this method is associated with the ability to quantitatively determine the elemental composition of a substance, high selectivity, simple preparation of dental samples under study, accuracy and sensitivity. Using spectrophotometer for experimental measurements, the spectral dependences of the absorption coefficient of the analyzed materials on the radiation wavelength were obtained over the entire measured range. The maximum and minimum values of the absorption coefficient of the materials were defined.
