E Faecalis Research Paper

E. faecalis is Gram positive cocci that occur singly in pairs or in short chains. It is a facultative anaerobe present in small proportion in the flora of untreated canal as a part of polymicrobial flora. However, it is a predominant bacteria implicated in root canal failures and persistent infections.4
E. faecalis has an ability to survive in harsh environments including extreme alkaline pH and salt concentrations.
Mostly in root canal infections, mechanical preparation and irrigation alone cannot eliminate all the bacteria from the infected root canal. In these cases, the use of intracanal medication is essential to help disinfect the infected root canal system.19
Despite careful instrumentation and antimicrobial irrigation; many initially
