Abstract

Objective

            The aim of this study was to evaluate the mechanical and adhesive properties of 3 different resin cements with 45S5 bioactive glass incorporated with two different ratios.

Methods

            Bioactive glass (45S5) was added to each resin cement at 5% and 10% by weight. Three-point bending strength, microhardness and bond strength were then evaluated. After evaluating the bond strength, fracture types were analyzed using a stereo microscope. Statistical analysis was performed using one-way ANOVA and Tukey tests (α < 0.05).

Results

            The addition of 45S5 bioactive glass reduced the flexural strength of the resin cements (p<0.05). The effect of BAG addition on Vickers microhardness value was significantly different for each cement group (p<0.05). It was observed that the addition of BAG weakened the bond strength in all resin cements except the GC Link Force group, which added 10% BAG (p=0.171).

Conclusions

            In vitro incorporation of 45S5 bioactive glass into resin cement resulted in materials with adequate mechanical properties.  Considering this, bioactive glass is a promising material for the development of bioactive and biocompatible resin cement materials for clinical use.
