Role and Treatment of the Enterococcus Faecalis’in Secondary Endodontic Infections

42117

E. faecalis has been frequently found in root canal-treated teeth in prevalence values ranging from 29% to 70% of the cases. E. faecalis survive very harsh environments including extreme alkaline pH and salt concentrations. E. faecalis possesses certain virulence factors including lytic enzymes, cytolysin, aggregation substance, pheromones, and lipoteichoic acid. Currently, use of good aseptic technique, increased apical preparation sizes, and inclusion of sodium hypochlorite and 2% chlorhexidine irrigants are the most effective methods to eliminate E. faecalis. Recent study has helped us better understand E. faecalis and the mechanisms that enable it to cause persistent endodontic infections.
