Comparison of antimicrobial substantivity of root canal irrigants in instrumented root canals up to 72 h: An in vitro study
Journal of Indian Society of Pedodontics and Preventive Dentistry , 04/29/2011
Shahani MN et al. – Disinfection of the root canal system can be achieved through the use of various antimicrobial agents in the form of irrigants and medicaments. The antimicrobial substantivity of 2% chlorhexidine gluconate, 1% povidone iodine, 2.5% hydrogen peroxide followed by 2% sodium hypochlorite, and 2% sodium hypochlorite alone as irrigants was assessed in instrumented root canals. 2% chlorhexidine showed antimicrobial substantivity lasting up to 72 h, followed by 1% povidone iodine, and 2% sodium hypochlorite. Thus 2% chlorhexidine should be used as a final rinse irrigant in endodontic treatment protocols.
