title: Apical leakage of epiphany root canal sealer combined with different master cones.
abstract: OBJECTIVE
  The aim of this study was to assess the apical sealing ability of different core materials used with Epiphany(TM) sealer and to evaluate the effect of Resilon/Epiphany(TM) system on creating an apical mono-block seal.
  
  
  METHODS
  Fifty-five extracted human teeth were used. Forty-five were selected and randomly divided into three groups and ten teeth were used as positive and negative control groups. In Group 1, roots were obturated using Resilon and Epiphany, In Group 2, roots were obturated using tapered single-cone gutta-percha and Epiphany and in Group 3, roots were obturated using Thermafil obturators and Epiphany sealer. The apical leakage was measured using the dye penetration methodology. The teeth were cleared, and the linear extent of dye penetration was measured with a stereomicroscope. Data were analyzed by the one-way ANOVA and Tukey HSD tests.
  
  
  RESULTS
  The teeth filled with Thermafil obturators and Epiphany sealer displayed the most apical leakage. The least apical leakage was shown with Resilon and Epiphany. Groups 1 and 2 had significantly leaked less than Group 3.
  
  
  CONCLUSIONS
  Based on the data of this study, although Resilon and Epiphany sealer showed the least apical leakage, statistical analysis showed no difference between gutta-percha and Epiphany.
