Comparative Evaluation of Antimicrobial Efficacy of Chlorhexidine and Herbal Root Canal Irrigant Aloe vera against Enterococcus faecalis: An in vitro Study

Root canal therapy provides appropriate environment for tissue healing by complete elimination of microorganisms from the root canal.The most commonly found bacteria in failed root canal is Enterococcus faecalis.Cleaning and shaping of canals along with chemical disinfection results in elimination of microorga nism.In recent years, there has been increasing interest in the use of herbs in endodontics as root canal irrigants.This study is designed to explore the antimicrobial efficacy of different concentrations of chlorhexidine (CHX) and Aloe vera extracts as a root canal irrigant against E. faecalis using agar diffusion method.
