Mechanical properties of resin containing microcapsules of various concentrations: (A) flexural strength, and (B) elastic modulus (mean ± sd; n = 6). 0% refers to resin containing 0% microcapsules, 5% refers to resin containing 5% microcapsules, and so on. Addition up to 15% of microcapsules resulted in no significant decrease in strength and elastic modulus of the resin. In each plot, values with dissimilar letters are significantly different from each other (p < 0.05).
