Abstract. The optical parameters of photopolymerized composites at temperatures of 20 and 47 °C and a constant photopolymerization time (10 s) are found by the spectrophotometric method. The dependences of the absorption coefficient on the wavelength of of Estelite Asteria samples of OcE, A3B, A3,5B, B3B shades are obtained. It is found that the optical quality of the restorations does not decrease when the composites are heate d.
