在这项研究中，测定了亲水性自酸蚀树脂在加和不加一层疏水性粘结剂的情况下树脂复合体与牙本质的微拉伸粘结强度。包括三种单步自酸蚀粘接剂，Adper Prompt L-Pop(3M ESPE)，iBond GI(Heraeus Kulzer，Inc.)和Xeno M(Caulk/Dentsply)，以及作为阴性对照的联黎Bond(GC America)，一种带有单独粘结剂的自酸蚀底漆。每种产品都使用其各自制造商的混合树脂复合材料进行评估，每个产品都按照说明使用，然后与其各自制造商提供的更疏水树脂的附加层一起使用。在72小时后，使用以0.6 mm/分钟的十字头速度进行的“非修剪”微拉伸测试。当按照制造商的使用说明使用时，iBond与牙本质的粘结强度显著高于其他三种产品(p
In this study, the microtensile bond strength of resin composites to dentin was determined when hydrophilic self-etching resins were used with and without an additional layer of a more hydrophobic adhesive. Included were three single-step self-etching adhesives, Adper Prompt L-Pop (3M ESPE), iBond GI (Heraeus Kulzer, Inc) and Xeno M (Caulk/Dentsply), and as a negative control, UniFil Bond (GC America), a self-etching primer with a separate adhesive. Each product was evaluated using a hybrid resin composite from its respective manufacturer, and each was used as directed and then used with an added layer of a more hydrophobic resin from its respective manufacturer. Testing was performed after 72 hours using a "non-trimming" microtensile test at a crosshead speed of 0.6 mm/minute. When the products were used according to manufacturers' directions, iBond had a significantly higher bond strength to dentin than the other three products (p
