The fracture toughness of dental composites. III. The effect of environment upon the stress intensification factor (KIC) after extended storage.
Three composite products were subjected to prolonged storage in four different environments. The fracture toughness parameter KIC was obtained for these by the fracture of SEN specimens. For each composite no significant differences were found between samples of material held in these conditions.
