Enterococcus faecalis infection in root canals - host-derived or exogenous source?

Letters in applied microbiology - 1 Feb 2011

Vidana R, Sullivan A, Billström H, Ahlquist M, Lund B

Abstract excerpt

AIMS: Enterococcus faecalis is associated with a significant number of refractory endodontic infections. Previous studies report a prevalence of Ent. faecalis ranging from 24% up to 77% in teeth with failed endodontic treatment. The origin of the micro-organism remains unclear, as enterococci do not belong to the normal oral microflora. The aim of this study was to determine whether these enterococci were of...
