A comparative study of the mechanical properties of some experimental composite resins containing various concentration of silver nanoparticles and bioactive glass with a controlled experimental and commercial hybrid composite resin
Objectives: The aim of this study was to develop a light cured restorative composite resin by adding various concentration of BAG and NAg which will hopefully not only satisfy the critical mechanical requirements of a restorative material but will also possess remineralizing capability and potent antimicrobial properties.
Methods: Composites with 70wt. % total filler content were prepared while substituting 0–15% of the filler with ground BAG and AgNPs. Fracture toughness, diametral tensile strength and Vickers hardness tests were performed with the help of universal testing machine and hardness tester. Mechanical properties of BAG and AgNPs composites were compared with the experimental and commercial composite Z250 XT by two way ANOVA and Tukey’s multiple comparison test (p≤0.05).
Results: Fracture toughness shows increase upto 10% BAG while shows decrease in 15% BAG group. Diametral tensile strength shows decrease with the addition of BAG. Vickers hardness was decreased except group containing 5% BAG. Mechanical properties of all the groups under investigation were low when compared to commercial hybrid composite resin.
Conclusions: The results demonstrated successful utilization of BAG as a promising biomaterial in resin composites. The mechanical properties can be further enhanced by increasing the percentage of filler in resin.
