Comparative evaluation of antimicrobial activity of pineapple extract (bromelain), 2% chlorhexidine, 5.25% sodium hypochlorite alone and in combination with bromelain as root canal irrigants against enterococcus faecalis atcc (29212): an in vitro study

Debridement and disinfection of the root canal system is a critical step in endodontic treatment. Most of the irrigants presently used in the endodontic treatment can have an impact on the microbes surviving in the biofilm but none of them are accomplish all of the required tasks. Researches are going on in order to produce an endodontic irrigant having ideal properties.
Aim and Objectives: Successful root canal treatment involves the complete elimination of microorganism from the root canal and the three‑dimensional obturation of the canal space. Enterococcus faecalis is the most commonly found bacteria in failed root canal. Chemical irrigation of canals along with biomechanical preparation helps in the elimination of microorganisms. The present study was aimed to evaluate the antimicrobial effect of Pineapple Extract (Bromelain), 2% Chlorhexidine, 5.25% Sodium Hypochlorite alone and in combination with Bromelain.
