摘要
目的：本研究旨在评估以两种不同比例添加生物活性玻璃（BAG）的三种不同树脂水门汀的机械和粘接性能：在不同的树脂水门汀（3M Rely-X Ultimate、GC Link Ace 和 GC Link Force）中以不同的比例（5% 和 10%（重量比））添加 BAG。对三点弯曲强度、显微硬度和粘接强度性能进行了评估。然后使用立体显微镜分析了各组的断裂类型。数据分析采用多因素方差分析和 Tukey 后检验（α < 0.05）：添加 BAG 会降低树脂水门汀的抗折强度（P < 0.05）。添加 BAG 对各组水门汀维氏硬度值的影响存在显著差异（P < 0.05）。此外，除 GC 连接力组（BAG 添加量为 10%）外，BAG 添加量降低了所有组别水门汀与牙本质的粘结强度（P = 0.171）：本研究结果证实，不同比例的 BAG 树脂水门汀具有不同的抗弯强度、硬度和粘结强度特性。由于在 GC Link Force 水泥组中添加 10% 的 BAG 后粘接强度值会增加，因此不同 BAG 成分的影响值得在今后的研究中进行探讨。
Effect of bioactive glass particles on mechanical and adhesion properties of resin cements.
Purpose: The aim of this study is to evaluate the mechanical and adhesive properties of three different resin cements with bioactive glass (BAG) incorporated in two different ratios.
Methods: BAG was added to different resin cements (3M Rely-X Ultimate, GC Link Ace, and GC Link Force) in different ratios (5% and 10% by weight). The three-point flexural strength, microhardness, and bond strength properties were evaluated. The fracture types of the groups were then analyzed using a stereo microscope. The data were analyzed using a multifactorial analysis of variance and Tukey's post-hoc tests (α < 0.05).
Results: The addition of BAG reduced the flexural strength of the resin cements (P < 0.05).The effect of BAG addition on the Vickers microhardness value was significantly different for each cement group (P < 0.05). In addition, with the exception of the GC link force group (10% BAG addition), the BAG addition decreased the bond strength of cements to dentin in all the groups (P = 0.171).
Conclusions: The results of this study confirmed that different resin cements comprising different ratios of BAG exhibited different flexural strength, hardness, and bond-strength properties. Since the bond strength values increased with the addition of 10% BAG in the GC Link Force cement group, the effects of different BAG compositions could be worth investigating in future studies.
