Table 2:
Storage Modulus at 40°C and glass transition temperature (Tg) for Thiol Michael composite and BisGMA/TEGMA composite with varying microfiller loadings as measured by DMA. The letters indicate statistically significant differences (p<0.05) via a one-way ANOVA and a Tukey’s post-hoc test (capital letters for row and lowercase for column).
