Abstract

Objectives: The aim of this study was to evaluate the bond strength of a new endodontic filling material containing added bioactive glass in comparison to a conventional polydimethylsiloxane-based material.

Materials and methods: Fourteen single-rooted teeth were chemo mechanically prepared, divided into two test groups and filled with the test material. The samples were embedded in acrylic resin and sectioned into 1 mm thick slices using a diamond saw. An average of 8 samples was obtained from each tooth (GuttaFlow2 n=37, GuttaFlow bioseal n= 34). The force required to fracture each individual sample was measured using the 'push out' test method. The Kolmogorov-Smirnov test assessed the 'bonding strength' distribution, and the Mann-Whitney U test compared bonding strength differences between the filling material groups.

Results: The Mann-Whitney U test showed no statistically significant difference between the two tested groups (P > 0.05).

Conclusion: No statistically significant differences in bond strength between tested materials were observed.

生物玻璃基根管充填材料的粘结强度评价。

目的：本研究的目的是评估添加生物活性玻璃的新型根管填充材料与传统聚二甲基硅氧烷基材料的结合强度。材料与方法：采用化学机械法制备14颗单根牙，分为两组，填充试验材料。样品被埋在丙烯酸树脂中，并用金刚石锯切成1毫米厚的薄片。平均每颗牙采集8个样本（GuttaFlow2 n=37, GuttaFlow bioseal n= 34）。断裂每个单独样品所需的力使用“推出”测试方法进行测量。Kolmogorov-Smirnov测试评估了“粘合强度”分布，Mann-Whitney U测试比较了填充材料组之间的粘合强度差异。结果：经Mann-Whitney U检验，两组间差异无统计学意义（P < 0.05）。结论：被试材料的粘结强度无统计学差异。
