The elastic constants of several commercially available filled and unfilled dental resin restorative materials were determined in the 0 to 50 kilobar range of pressure. Measurements of the velocities of propagation of longitudinal and shear ultrasonic waves were used to obtain the Young's, bulk, and shear moduli and Poisson's ratio as a function of pressure; atmospheric pressure values were obtained by back extrapolation from the high pressure data.
