Curing processes of resin dental composites is connected with shrinkage stresses. It might influence the quality of dental restorations. Researchers make effort to reduce generated stresses. One of the methods is physical modification performed by changing the conditions of polymerization process. In this study the effect of the curing mode and the light intensity of selected curing lamps on the properties of Filtek Z550 was investigated. For this purpose, photoelastic studies were performed. Transparent and photoelastically sensitive plates made of epoxy resin were used in evaluation of contraction stress, that generates during photopolymerization of resin composites. The study also included microhardness and diametral tensile strength testing. The results show the relationship between cure method and reduction of generated shrinkage stresses. The concentration of stresses generated by material Filtek Z550 during photopolymerization were reduced significantly (in each case not less than 35%). The conventional cured samples had the highest value of DTS and HV1. There are no statistically significant differences between DTS and HV1 of the differently (method I–V) polymerized samples.
