Enterococcus faecalis is the most isolated or detected species from oral infections including marginal periodontitis, infected root canals, periradicular abscesses and also detected in cases of failed endodontic therapy. To prevent endodontic treatment failure irrigation is mandatory for the effective removal of smear layer, pulp tissue, and microorganisms. Cultivation and other traditional identification methods have been demonstrated to have several limitations when it comes to microbiological identification. Polymerase chain reaction was selected because it has an added advantage over traditional microbiological methods. Materials and Methods: Twenty single rooted premolars were taken were taken stored in 0.1% thymol solution at 4°C decoronated to obtain 12 mm length, teeth were autoclaved at 121°C, canals were instrumented up to 35k file (International Organization for Standardization). The samples were randomly divided into three groups Group I - 5.25% sodium hypochlorite (NaOCL) and 17% ethylenediaminetetraacetic acid (EDTA), Group - II 5.25% NaOCL and 2% chlorhexidine (CHX), Group III - 5.25% NaOCL and 17% EDTA and 2% CHX. Results: The results showed that Group III which is 5% NaOCl followed by 17% EDTA and followed by 2% CHX showed maximum antimicrobial activity in all the three different time intervals.
