Method 45 single root canals were prepared , autoclaved and infected by Enterococcus faecalis and were divided randomly in to three groups. Different irrigants were used , the immediately and 7 days after irrigation microbiological samples were taken and counted the CFU. Results The 2% CHX and 2.5% NaOCl significantly reduced E, faecalis and 2%CHX had lower CFU count 7 days after irrigation. Conclusion The 2%CHX was effective and substantive as endodontic irrigants against Enterococcus faecalis even after 7 days.
