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.
