title: Endodontic sealers: Intratubular penetration and permeability to Enterococcus faecalis.
abstract: OBJECTIVE
  Evaluate in vitro the intratubular penetration and permeability of endodontic sealers in teeth contaminated with Enterococcus faecalis.
  
  
  METHODS
  Human canines were filled with AHPlus , Endo CPM-sealer or EndoRez sealers. To evaluate permeability, the coronary portion of each tooth was contaminated with E. faecalis, then the apical portion was immersed in brain heart infusion (BHI) broth, and medium turbidity was observed for thirty days. Scanning electron microscope (SEM) was used to evaluate the intratubular penetration of each sealer at the cervical, middle, and apical thirds of the tooth.
  
  
  RESULTS
  Only one tooth from the Endo CPM-sealer group presented broth contamination. EndoRez showed increased intratubular penetration compared to AHPlus and Endo CPM-sealer.
  
  
  CONCLUSIONS
  Endo CPM-sealer showed greater permeability to E. faecalis and EndoRez showed increased intratubular penetration.
