title: Evaluation of apical sealing ability of four different sealers using centrifuging dye penetration method: an in vitro study.
abstract: OBJECTIVE
  The aim of this in vitro study was to evaluate the apical seal obtained with four root canal sealers AH 26, Sealapex, Endoflas FS and AH Plus, with lateral condensation.
  
  
  METHODS
  Sixty root canals were prepared using the step-back technique. The specimens were divided into four experimental groups of 12 teeth and two control groups of 12 teeth. The experimental groups were obturated by laterally condensed gutta-percha with one of the tested sealers and control groups were obturated without any sealer. Methylene blue dye penetration with centrifuging method was used to evaluate the apical sealing ability. The quantitative apical leakage of each specimen was measured after 2 weeks.
  
  
  RESULTS
  The results showed no significant differences between all groups except between AH Plus and Endoflas FS (<0.05). AH Plus showed significantly less leakage than Endoflas FS.
  
  
  CONCLUSIONS
  AH Plus showed the least leakage compared to AH 26, Sealapex and Endoflas FS.
