Dental Restorative

The effect of temperature on the rheological properties of four dental restorative materials was investigated at 26 to 60 C. Acoustic absorption was used to calculate loss coefficient, and resonance frequency was used to obtain Young's modulus. Young's moduli and loss coefficients of the restorative materials were temperature dependent.

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.

Selection Of

A wide variety of dental products that are launched on the market becomes the correct selection of these materials a difficult task. Although the mechanical properties do not necessarily represent their actual clinical performance, they are used to guide the effects of changes in their composition or processing on these properties. Also, these tests might help somehow the clinician to choose once comparisons between former formulations and new ones, as well as, with the leading brand, are highlighted by manufactures. This paper presents a review of the most important laboratory tests. In this manner, the knowledge of these tests will provide a critical opinion related to the properties of different dental materials.
