Dental composite materials which are used as tooth fillings have numerous advantages and disadvantages in comparison to previously used alternative materials. Effects of polymerization shrinkage (light curing) of composite polymer materials which occur after illuminating with a LED lamp can cause problems in dental practice. Considered in this paper were the mechanical consequences which can occur due to light curing, along with strain fields for composites Z250, TetricEvoCeram and Silorane, as well as strain on a separate circular section that have occurred before and after light curing, by using the DIC method.
