study aimed to evaluate the antibacterial activities and dentin bond
strengths of silver nanoparticles (Ag NPs) and silver nano-graphene
oxide nanocomposites (Ag@nGO NCs) produced by green and chemical
synthesis methods added to the dental adhesive. Ag NPs were produced by
green synthesis (biogenic) (B-Ag NPs) and chemical synthesis methods
(C –Ag NPs) and deposited on nGO (nano-graphene oxide). Ag NPs and Ag@nGO
NCs (0.05% w/w) were added to the primer and bond (Clearfil SE Bond).
Group 1: control, Group 2: nGO, Group 3: B-Ag NPs, Group 4: B-Ag@nGO
NCs, Group 5: C–Ag NPs, Group 6: C–Ag@nGO NCs.Streptococcus mutans (S. mutans)
live/dead assay analysis, MTT metabolic activity test, agar disc
diffusion test, lactic acid production, and colony forming units (CFUs)
tests were performed. Bond strength values were determined by the
microtensile bond strength test ( μTBS). Failure types were determined by
evaluating with SEM. Statistical analysis was performed using one-way
ANOVA and two-way ANOVA (p < 0.05). There was a difference between the groups in the viable bacteria ratio and lactic acid production tests (p < 0.05). When the inhibition zone andS. mutans CFUs were evaluated, there was no difference between Group 3 and Group 4 (p > 0.05), but there was a difference between the other groups (p < 0.05). When the metabolic activity ofS. mutans...
