Abstract

This in vitro study concerns the modulus of elasticity, Young’s modulus, and compares physical characteristics for six reinforced dental materials. Young’s modulus is the measurement of stress per strain that the material can withstand before catastrophic failure. In a through study by Braem et al. over 40 posterior composites were tested and the Young’s modulus was measured using a non-destructive technique. Feilzer et al. in a similar study tested four posterior composites. In these studies no measurements were performed for core materials or cementation agents.
