The Comparison of Dentin Adaptation and Sealing Ability of Gutta-percha/Ah Plus, Resilon/Epiphany Se, Endorez: an In-Vitro Study

Abstract

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, gutta-percha/AH Plus had the lowest core to total area ratio (p<0.05). At 1 mm level, EndoREZ had significantly lower sealer+debris+voids ratio than other groups, while gutta-percha/AH Plus had the highest sealer+debris+void areas/total areas at 3 mm (p<0.05). When core, sealer, and voids areas were examined within groups, significant differences were found in the ratios of group GA and group RE at different cut sections. Results are consistent with the previous findings. On the other hand, there are some contradictory results as well. Conflicting findings might result from the differences in the methods of measurement. Moreover, filling materials that are away from the biological cycle may limit in vitro studies. At 1 mm there are not significantly core areas/total areas group GA and group RE. At 3 and 5 mm level group GP had significantly lower core areas/total areas © 2017, Yuzuncu Yil Universitesi Tip Fakultesi. All rights reserved.
