OBJECTIVE
This study evaluated the effect of two different eugenol-based root canal sealers on the retention of prefabricated metal posts luted with adhesive resin cement.
MATERIALS AND METHODS
Thirty prefabricated ParaPosts randomly divided among three groups of 10 each were luted into extracted single-rooted teeth with adhesive resin cement. Two of the groups had been obturated with Gutta-Percha and one of two eugenol-based root canal sealers (Endofil and Tubli-Seal), respectively. The third group was not obturated and served as the control. The forces required for dislodgment of posts from their prepared post spaces were recorded using a universal testing machine. Data were statistically analyzed using one-way ANOVA and Tukey's multiple range test was used to determine the mean differences.
RESULTS
Endofil and Tubli-Seal groups demonstrated significantly reduced retention compared to the unobturated (control) group (P < 0.05).
CONCLUSION
Eugenol-based sealers significantly reduced the retention of prefabricated posts luted with adhesive resin cement.
目的
本研究评估了两种不同的丁香酚类根管封闭剂对用粘结树脂水门汀粘结的预成金属桩固位力的影响。
材料与方法
将30个预成Para桩随机分为三组，每组10个，用粘结树脂水门汀粘结到拔除的单根牙中。其中两组分别用牙胶和两种丁香酚类根管封闭剂（Endofil和Tubli-Seal）之一进行根管充填。第三组未进行根管充填，作为对照组。使用万能试验机记录将桩从制备的桩道中拔出所需的力。数据采用单因素方差分析进行统计学分析，并用Tukey多重极差检验确定均值差异。
结果
与未充填（对照）组相比，Endofil组和Tubli-Seal组的固位力显著降低（P < 0.05）。
结论
丁香酚类封闭剂显著降低了用粘结树脂水门汀粘结的预成桩的固位力。
