The Young's modulus of 15 commercial dental particulate filled composites was measured with three different methods. The materials were tested with static, low-frequency, and high-frequency elastic deformations. The analysis of the results shows that the frequency dependence of the Young's modulus of elasticity follows the same empirical law for all frequencies. Furthermore, knowledge of the Young's modulus for the resin component at all frequencies suffices to predict the Young's modulus of any particulate-filled composite.
