Antibacterial effect of endodontic sealers containing quaternary ammonium polyethylenimine nanoparticles on intratubular Enterococcus faecalis.
Objectives: To evaluated the efficiency of an endodontic sealer incorporating with QPEI nanoparticles against intratubular E. faecalis. Methods: Human extracted teeth were incubated with E. faecalis for seven days before being treated with a standard RCT. The antibacterial effect of incorporated QPEI nanoparticles into an endodontic sealer was tested at 0% and 1% wt/wt concentrations Results: Results showed significant reduction in bacterial viability (p<0.01) in the teeth that were sealed with the endodontic sealer incorporating QPEI. Conclusions: In conclusion, the addition 1% of QPEI into endodontic sealers may eliminate E. faecalis in the dentin tubules and thus prevent bacterial reinfection.
