An in Vitro Comparative Study of Nanoparticles Containing Sodium Hypochlorite to Other Irrigants as a Main Irrigant Material against E.faecalis Biofilm
Research problem and objectives: The most important material used as an irrigant in root canal treatment is sodium hypochlorite. Its antibacterial activity could be inactivated by dentin and the biomass in the root canal; also, it is a known irritant to periapical tissues. The purpose of this study was to examine the antibacterial activity and cytotoxicity of propolis and chitosan nanoparticles incorporated with 2.5% NaOCl also To make Physicochemical characterization of new development Endodontic irrigation.
