ABSTRACT
Objective:
To analyse viable Enterococcus faecalis(E.faecalis)in root-well-filled teeth associated with failed endodontic treatment by using propidium monoazide (PMA)in combination with real time qPCR.Methods:
Bacterial samples were extracted from 34 root-canal-treated teeth with post-treatment apical periodontitis.Each sample was separated into 2 different tubes.PMA was added to one of the tubes,and the other was left untreated.Then,DNA extraction and qPCR were performed.Results:
E.faecalis was found in 20 of the 34 samples(58.8%).In PMA treated and none-treaten samples the Ct value of E.faecalis was 25.1 2 ±2.04 and 24.62 ± 2.02 respectively(P =0.001 ).Conclusion:
PMA may be feasible in differentiating viable and dead Enterococcus faecalis cells.
