Gutta percha cones are radiopaque cones that are used to fill and seal the canal after undergoing endodontic therapy.The success of endodontic treatment is determined by the biochemical preparation and the use of sterilized techniques during the procedure.Care should be taken during the treatment to avoid contamination of instruments and filling materials as this is to avoid cross - infection in the root canal .Various disinfection have been used to sterilize guttad-percha cones including sodium hypochlorite (NaOCl).The aim of this study is to evaluate and compare the efficiency of 3% of NaOCl , Cidex solution and 17% of Edta in disinfecting gutta-percha cones after immersing it into bacterial suspension of enterococcus faecalis.Twelve gutta percha cones of size 70 were used in this study were divided into various groups depending upon the type of solution 3% NaOCl solution,Cidex Solution, 17% EDTA solution with time of exposure to each solution (15 min) and type of microorganism (Enterococcus Faecalis )Sodium Hypochlorite was found to be effective disinfectant.The outcome of this study confirmed the efficacy of 3% NaOCl in the disinfection of gutta percha cones.
