Abstract

Shrinkage stresses applied to cavity wall due to the polymerization of a light-cured composite resin were studied experimentally and analytically to understand the stress generation mechanism. The shrinkage forces were evaluated using artificial cylindrical cavities and a load cell. The cavities were filled with a composite resin and then irradiated with a light-curing unit. The forces were determined for different cavity depth and irradiation intensity and time using two kinds of light-curing unit. An analytical model was introduced to estimate the shrinkage stress as a function of the cavity depth, and the stress values were evaluated from the comparison with experimental data.
