EFFICACY OF SILVER NANOPARTICLES AGAINST ENTEROCOCCUS FAECALIS AN IN VITRO STUDY

Abstract

The success of root canal treatment is mainly based on the complete eradication of micro organisms by instrumentation and disinfection protocols followed during the procedure Due to anatomical complexities achieving long term success would be difficult because these areas have limited access to instruments and irrigants Hence application of intracanal medicament has been considered as an important step to reduce the persistent bacteria inside the root canal Since the routine intracanal medicaments could not penetrate into the dentinal tubules the role of Nantotechnology was explored in Endodontics The field of nanotechnology has the ability of synthesising the metals in nanosize which drastically changes the chemical physical and optical properties of metals The aim of the present study was three fold i antibacterial efficacy of AgNps against E faecalis ii biocompatibility of AgNps by haemolytic assay iii effect of AgNps on the microhardness of root dentin In the present study AgNps was synthesised at 4 mM 6 mM 8 mM 10 mM and 100 mM concentrations
