Abstract
Rheological properties of aged specimens of four restorative materials were investigated at 37 C by a nondestructive test method using an acoustic spectrometer. An amalgam was found to have the highest Young's modulus and lowest dynamic viscosity. A Poisson's ratio of about 0.2 was obtained for all of the dental restoratives.Keywords
