The flexural strength (A), flexural modulus (B) of Bis-GMA/TEGDMA dental composites filled with varied mass fractions of MA-POSS and MI-POSS.
Notes: Data are presented as mean and standard deviation, n=6, two-way analysis of variance. The same letters in the bar indicate no significant differences of different POSS concentration (P>0.05); Uppercase letters represent the statistical result of MA-POSS under different concentrations, and lowercase letters represent the statistical result of MI-POSS under different concentrations. If the same letters aren’t shown on the two bars, the result of the two concentrations was found to be statistically different.*Indicates significant differences between two types of POSS (P<0.05).
Abbreviations: Bis-GMA, bisphenol A glycerolate dimethacrylate; MA-POSS, methacryl polyhedral oligomeric silsesquioxanes; MI-POSS, methacryl isobutyl polyhedral oligomeric silsesquioxanes; TEGDMA, tri(ethylene glycol) dimethacrylate.
