Abstract

The coefficient of dimensional change (CDC) of tooth-colored restorative materials was investigated. A thermal mechanical analyzer was employed to determine the CDC for each specimen, by heating the sample from 25 to 70°C at 10°C per minute. The investigations show that all materials except the glass ionomers, expand on heating. The temperature response was found to be nonlinear and values of CDC were, therefore, calculated between 25 and 50°C and between 50 and 70°C.
