Antibacterial activity of glass ionomer cement modified by zinc oxide nanoparticles.

摘要: This study evaluated the antibacterial activity of zinc oxide nanoparticles incorporated into self-cured glass ionomer cement (GIC) and light-cured resin-reinforced GIC on Streptococcus mutans biofilm. The GICs, Fuji II (GC America) LC America), were with at concentrations 0%, 1%, 2% by weight, biofilm maturation time was one seven days. Circular specimens each type prepared. determining number colony forming units S. strain per milliliter. Morphology analyzed scanning electron microscopy (SEM). data obtained for two-way ANOVA (α = 5%). For chemically activated GIC, no significant difference observed in relation to (p 0.744), concentration 0.966), their interaction 0.800). results from analysis modified light-polymerized resin showed that only maturing significantly affected adhered cells 0.034, F 4.778). more mature biofilm, higher cells. SEM change cell morphology time, concentration. We conclude inclusion 1% weight GICs here, did not promote antimicrobial against mutans.
