Data on changes in flexural strength and elastic modulus of dental CAD/CAM composites after deterioration tests.


ABSTRACT: Mechanical properties of dental restorative materials are important for clinical success in prosthodontic care. However, open data on the mechanical properties of these materials are limited. This article provides data on the flexural strength and elastic modulus of dental composites in practical use for design/computer-aided manufacturing (CAD/CAM) systems. Eight brands of composites were subjected to deterioration tests: immersing in water at 37 °C for one day or seven days, or thermocycling (TC) in water at temperatures between 5 °C and 55 °C for 5000 or 10,000 cycles. The mechanical properties of the samples were measured by using a three-point bending test according to ISO 6872. The obtained values were statistically analyzed using one-way analysis of variance (ANOVA), followed by Tukey multiple comparison tests.
