我们评估了不同固化策略的通用胶粘剂的树脂水泥和牙本质之间和/或树脂水泥和间接树脂复合材料之间的微拉伸粘结强度（亩TBS）的影响。用含硅烷的通用粘合剂预处理扁平冠状牙本质表面和复合树脂盘，在牙本质侧和/或复合树脂盘侧进行光固化或不进行光固化。将树脂盘用相应的双固化粘接剂粘固在预处理的牙本质表面上，光固化，水储存24 h后切割成梁。在水浴中进行0或10，000次热循环（5 ℃/55 ℃）后，测试复合树脂盘-牙本质梁的μ TBS。当通用粘合剂应用于牙本质和间接复合树脂盘侧时，mu TBS最高，其次是光固化。除了Scotchbond Universal治疗组外，所有热循环均降低了mu TBS，两侧均进行光固化。固化策略的效果取决于材料。
We evaluated the effect of different curing strategies for universal adhesives on micro-tensile bond strength (mu TBS) between resin cement and dentin and/or between resin cement and indirect resin composite. Flat coronal dentin surfaces and composite resin disks were pretreated with silane-containing universal adhesives, with or without light-curing on the dentin-side and/or composite resin disk-side. Resin disks were luted onto the pretreated dentin surfaces with the corresponding dual-cure adhesive resin cements and light-cured, and cut into beams after 24-h water storage. After 0 or 10,000 thermocycles (5 degrees C/55 degrees C) in a water bath, the mu TBS of the composite resin disk-dentin beam was tested. The mu TBS was highest when universal adhesives were applied to both the dentin- and the indirect composite resin disk-side, followed by light-curing. Thermocycling decreased mu TBS in all but the Scotchbond Universal-treated group, with light-curing on both sides. The effect of curing strategies is dependent upon the materials.
