Mechanical and Antibacterial Properties of h-BN-TiO2 Nanocomposite-Modified Glass Ionomer Cement

This study investigated the mechanical properties and antibacterial of hexagonal boron nitride titanium dioxide (h-BN-TiO 2 ) nanocomposite modified traditional glass ionomer cement. The mechanism formation h-BN-TiO was elucidated by conducting molecular dynamics (MD) simulations using Material Studio (MS) software. Furthermore, synthesis original growth method nanosheets (h-BNNs) nanoparticles (TiO Nps) characterization TEM AFM to determine their particle sizes, morphologies, structures. efficacies cement composites were analyzed based on different mass fractions (0, 0.3, 0.7, 1.1, 1.5 wt%) nanocomposite. results showed when concentration 1.1 wt%, Compressive strength (CS) Vicker hardness (VHN) 80.2% 149.65% higher, respectively, compared without any Also, increase in led a decrease both coefficient friction (COF) solubility, but 93.4% composites. cell survival rate each group more than 70% after 48 h, difference not statistically significant ( p > 0.05). Therefore, served as reinforcing material for cement, which can be useful clinical dentistry provide new strategy improving utility
