Apical Leakage of Epiphany Root Canal Sealer Combined with Different Master Cones

OBJECTIVES: 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™.
