This study compared the bond strength of resinous adhesives used to bond amalgam to dentin. The adhesives were: All-Bond 2 (AB), Liner-F (LF), SuperBond C&B (SB), Amalgambond (AM), Photo Bond (PB), and Panavia (PA). Occlusal surfaces of non-carious molars were ground wet to 600 grit finish, exposing dentin. The dentin surfaces were conditioned and the adhesives were applied according to manufacturers' instructions. Dispersalloy amalgam (D) was condensed onto the adhesive immediately. For comparison, resin composite, Photo Posterior (PO) and Bis-Fil (BIS) were used. After 24 hours of storage in 100% humidity at room temperature, shear bond strengths were determined with a shear testing jig in an Instron testing machine at a crosshead speed of 0.5 mm/minute. The data were compared using ANOVA, P < 0.01. AB, LF, D had significantly higher bond strengths than other amalgam adhesives. There was no significant difference between SB, D and PB, PO. Bond strength of PB, PA, D was significantly higher than PA, D. Thus, there were significant differences among adhesives for bonding amalgams. Amalgam to dentin and composite to dentin bond strength were comparable except for the All-Bond groups. Fracture patterns at the dentin/restoration interfaces were examined by scanning electron microscopy (SEM).
本研究比较了用于将汞合金粘结至牙本质的树脂类粘结剂的粘结强度。这些粘结剂分别为：全粘结剂2（AB）、衬层-F（LF）、超强粘结剂C&B（SB）、汞合金粘结剂（AM）、光固化粘结剂（PB）和帕纳维亚粘结剂（PA）。对无龋磨牙的咬合面进行湿磨至600目光洁度，暴露出牙本质。对牙本质表面进行预处理，并按照制造商的说明应用粘结剂。立即将Dispersalloy汞合金（D）压实到粘结剂上。作为对照，使用了树脂复合材料、光固化后牙材料（PO）和双氟树脂（BIS）。在室温100%湿度下储存24小时后，在Instron测试机中使用剪切测试夹具以0.5毫米/分钟的十字头速度测定剪切粘结强度。使用方差分析对数据进行比较，P<0.01。AB、LF、D的粘结强度显著高于其他汞合金粘结剂。SB、D与PB、PO之间无显著差异。PB、PA、D的粘结强度显著高于PA、D。因此，在粘结汞合金的粘结剂之间存在显著差异。除全粘结剂组外，汞合金与牙本质以及复合材料与牙本质的粘结强度具有可比性。通过扫描电子显微镜（SEM）检查牙本质/修复体界面处的断裂模式。
