title: Radiopacity of a new root canal sealer, Epiphany.
abstract: OBJECTIVE
  The purpose of this study was to evaluate the radiopacity of a new root canal sealer, Epiphany, relative to 3 other root canal sealing materials, AH 26, Sealapex, and Ketac-Endo.
  
  
  METHODS
  Radiographs were taken of 1-mm-thick specimens of 4 root canal sealers and dentine slides, as well as a range of aluminum thicknesses, by using a step-wedge. The radiographic density of each specimen was measured and correlated with the equivalent thickness of aluminum.
  
  
  RESULTS
  All sealers were found to be more radiopaque than dentine (1.05 +/- 0.2-mm aluminum) and to possess radiopacity of greater than 3-mm aluminum. The radiopacity values reported in this study were 11.27 +/- 0.18-mm, 10.88 +/- 0.16-mm, 10.35 +/- 0.15-mm, and 9.78 +/- 0.21-mm aluminum for Sealapex, Ketac-Endo, Epiphany, and AH 26, respectively, which were significantly different from each other (P < .01).
  
  
  CONCLUSIONS
  Radiopacity measurements for Epiphany, Ketac-Endo, Sealapex, and AH 26 exceeded the minimum standard for root canal sealers. Epiphany has higher radiopacity than dentine. Therefore, this sealer is suitable for endodontic usage in terms of radiographic assessment.
