摘要：

The purpose of this in vitro study was to assess the active versus passive dye microleakage and apical sealing ability of laterally condensed gutta-percha/AH Plus versus Resilon/Epiphany. One hundred and twenty teeth were instrumented and divided into experimental, positive and negative control groups. In group 1, the teeth were obturated with gutta-percha/AH Plus and in group 2 the teeth were obturated with Resilon/Epiphany. The apical seal was evaluated with a passive and active dye penetration test. Absorbance of the extracted dye was determined with a spectrophotometer. Resilon/Epiphany showed less dye penetration in comparison with the gutta-percha/AH Plus group (P < 0.05). There were no statistically significant differences between the passive and active dye penetration tests (P > 0.05). In this in vitro study, canals obturated with Resilon/Epiphany showed less apical leakage than those obturated with gutta-percha/AH Plus, regardless of the type of dye penetration test used.
