Enterococcus faecalis: A resistant microbe in endodontics

Enterococcus faecalis is commonly detected in endodontic infections that are asymptomatic, persistent and recurrent. They are the microorganisms mainly responsible for persistent periradicular lesions even after root canal treatment. It can survive in the root canal as a single organism or as a major component of the flora. This article highlights the characteristics of E. faecalis, the factors responsible for its virulence and survival, as well as the effect of disinfectants on E. faecalis. Knowledge regarding this microorganism may help to prevent endodontic treatment failures caused by this organism.
