title: Dislocation resistance of iRoot SP, a calcium silicate-based sealer, from radicular dentine.
abstract: BACKGROUND
  The aim of this study was to evaluate the push-out bond strength of iRoot SP (Innovative Bioceramix, Vancouver, Canada) and compare it with that of other widely used root canal sealers.
  
  
  METHODS
  Sixty extracted human maxillary canines were sectioned transversally below the cement-enamel junction to obtain 120 4-mm-thick dentin disks that were randomly divided into four groups (n = 30) for treatment with one of four different root-canal sealers (iRoot SP, AH Plus [Dentsply DeTrey GmbH, Konstanz, Germany], Sealapex [SybronEndo Corporation, Orange, CA], EndoREZ [Ultradent Inc, South Jordan, UT]). Standardized cavities were prepared to simulate root canals, cavities were filled with sealer material, and push-out bond-strength testing was performed using a universal testing machine. Failure modes were assessed quantitatively under a stereomicroscope and morphologically under a scanning electron microscope. Statistical analysis was performed using one-way analysis of variance and the post hoc Tukey test, with the significance level set at 0.05.
  
  
  RESULTS
  Bond strengths of iRoot SP and AH Plus were significantly higher than those of Sealapex and EndoREZ. There was no significant difference between the bond strength of iRoot SP and AH Plus (p = 0.274).
  
  
  CONCLUSIONS
  iRoot SP and AH Plus performed similarly and better than EndoREZ and Sealapex in terms of bond strength.
