title: Compressive stress relaxation measurements of selected dental restorative composites.
abstract: Compressive stress relaxation measurements were performed on specimens of selected dental restorative composites. The relaxation modulus showed a linear dependence on the logarithm of time. The values obtained indicated that stress was dissipated more rapidly in dental composites than in enamel, but less rapidly than in human dentin.
