The comparison of dentin adaptation and sealingability of gutta-percha/AH Plus, Resilon/Epiphany SE,EndoREZ: an in-vitro study

The aim of this study compares three different root canal filling systems (gutta-percha/AH Plus, Resilon/Epiphany SE, EndoREZ) regarding their adaptation root to dentine and their sealing ability at different horizontal sections. One Hundred extracted single root maxillary incisors were randomly assigned into 3 groups and filled gutta-percha/AH Plus (group GA), Resilon/Epiphany SE (group RE) or EndoREZ root canal filling system (group EZ). All teeth were sectioned horizontally at 1, 3, and 5 mm from apex. Then teeth layers were examined with stereomicroscope. The ratios of the areas containing core material, sealer and/or voids to the total area were calculated and analyzed statistically. EndoREZ had significantly more core areas/total areas ratio at 1 mm compared to the other systems. At 3 mm level, guttapercha/AH Plus had the lowest core to total area ratio (p
