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.
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.
The Mann-Whitney U test showed no statistically significant difference between the two tested groups (P > 0.05).
No statistically significant differences in bond strength between tested materials were observed.
本研究旨在评估一种添加了生物活性玻璃的新型根管充填材料与传统聚二甲基硅氧烷基材料相比的粘结强度。
选取14颗单根牙进行化学机械预备，分为两个试验组，并用试验材料进行充填。将样本嵌入丙烯酸树脂中，使用金刚石锯切成1毫米厚的薄片。每颗牙齿平均获得8个样本（GuttaFlow2 n = 37，GuttaFlow生物封闭剂n = 34）。使用“推出”试验方法测量使每个单独样本断裂所需的力。Kolmogorov-Smirnov检验评估“粘结强度”分布，Mann-Whitney U检验比较充填材料组之间的粘结强度差异。
Mann-Whitney U检验显示两个试验组之间无统计学显著差异（P > 0.05）。
在测试材料之间未观察到粘结强度的统计学显著差异。
