Popis: Enterococcus faecalis is the most common bacterial species in resistant or recurrent infections due to its penetration in deep dentinal layers which is difficult to clean leading to endodontic treatment failures . It compromises 6% of total flora in root canal and seen in 22_77% root canal retreatment cases as it has many virulence factors .intracanal heating has better antimicrobial efficacy in comparison to extra-canal heating of sodium hypochlorite and at room temperature .Storage of sodium hypochlorite in refrigerated environment is proved to be the best option to avoid the marked loss of active chlorine in sodium hypochlorite of concentration at 6%.The more the content of free chlorine means the more the antibacterial activity.so intra canal heated sodium by system B at 180°C ,cryotreated sodium hypochlorite at 2_4 °C will be compared by sodium hypochlorite at room temp for thier antimicrobila efficacy againest E.faecalis
