Enterococcus faecalis is the main pathogen detached from failed root canals and insistent peri-apical lesion. It founds in anatomical structures that remain inside inaccessible areas for mechanical instrumentation like lateral canal and isthmus so, the root canal irrigation has an important role in the elimination of microbes in these inaccessible areas for instrumentation. Aim of the study is to compare between the efficiency of a newly introduced product of chlorhexidine gluconate as chemical root canal irrigant and hydroalcoholic extract of garlic herbal product against Enterococcus faecalis. This study was In-vitro used the agar diffusion method. | A comparative study to evaluate antimicrobial activity of hydroalchoholic extract of garlic and 2 chlorhexidine gluconate root canal irrigant against enterococcus faecalis In vitro study
