title: Sealing ability promoted by three different endodontic sealers.
abstract: BACKGROUND
  The aim of this study was to evaluate the apical and coronal seal of endodontic filling promoted by the combined use of Sealer 26/gutta-percha, Endofill/gutta-percha and Resilon/ Epiphany.
  
  
  METHODS
  A total of 38 extracted human canine teeth were selected; 10 teeth for each test group and 4 for each control group. After conducting conventional endodontic treatment, the teeth were immersed in saline solution for thirty days, and subsequently sealed and stored in India ink for seven days. They were then cleaned and evaluated for infiltration by stereoscopic microscope. The data were statistically analyzed by ANOVA and Bonferroni tests.
  
  
  RESULTS
  The results showed no significant differences between the three groups of filling materials used.
  
  
  CONCLUSIONS
  Within the limitations of this in vitro study, no material showed superiority in their apical and coronal seal.
