Evaluation of the Antimicrobial Effect on Enterococcus Faecalis of Bioceramic Cements with and without Silver Nanoparticles.
Objective: To compare the antimicrobial effect of bioceramic endodontic cements with and without silver nanoparticles on Enterococcus faecalis.
Materials and methods: Six groups were evaluated (n=8), and divided according to the materials: MTA Flow + AgNP ; MTA Flow Group; Bio C Repair + AgNP; Bio C Repair; PBS Cimmo + AgNP; PBS Cimmo. The groups were maintained for 72 h in the suspension of Enterococcus faecalis in Simulated Body Fluid (SBF). Samples of 100 μL were removed from the suspension at 0, 24, 48 and 72 h and seeded in triplicate in a Petri dish. Colony forming units (CFU) were counted using a colony counter. All procedures described were performed in a laminar flow chamber. Two-way ANOVA followed by Tukey's post hoc test and paired t-test were used for statistical analyses (α = 0.05).
Results: The addition of silver nanoparticles resulted in a statistically significant difference for MTA and CIMMO PBS cements (p⟨0.05), with the lowest bacterial growth being shown by the MTA group. For all groups, only the times of 48 and 72 h presented results without differences.
Conclusion: The addition of silver nanoparticles to bioceramic cements was efficient to promote an acceleration of bacterial death.
