The aim of this study was to compare the fracture resistance of roots obturated with different materials.
Sixty root canals were instrumented and divided into 4 equal groups (n = 15 each). The root canals in group 1 were filled with AH26 sealer and gutta-percha, in group 2 with Resilon and Epiphany, and in group 3 with Ketac-Endo Aplicap and gutta-percha. Fifteen root canals had no obturation. The force required to fracture was recorded. The data was analyzed with analysis of variance and Duncan test.
The mean force of fracture for group 1 was significantly higher than for the other 3 groups (P < .05). There was significant difference between group 2 and group 3 (P < .05). Group 2 and group 3 were not significantly different from the control group (P > .05).
The use of AH26 + gutta-percha increased the fracture resistance of instrumented root canals compared with Resilon + Epiphany and Ketac-Endo Aplicap + gutta-percha.
本研究旨在比较用不同材料充填根管后的牙根抗折性。
对60个根管进行预备，并分为4个相等的组（每组n = 15）。第1组根管用AH26封闭剂和牙胶充填，第2组用Resilon和Epiphany充填，第3组用Ketac-Endo Aplicap和牙胶充填。15个根管未进行充填。记录牙根折断所需的力。采用方差分析和邓肯检验对数据进行分析。
第1组的平均折断力显著高于其他3组（P < .05）。第2组和第3组之间存在显著差异（P < .05）。第2组和第3组与对照组之间无显著差异（P > .05）。
与Resilon + Epiphany和Ketac-Endo Aplicap +牙胶相比，使用AH26 +牙胶可提高根管预备后牙根的抗折性。
