To evaluate the bonding efficacy of five commercial and one experimental one-component enamel/dentin adhesives.
The adhesives One-Step (BOS), Primabond (PAB), Prime & Bond 2.0 (PB2), Solist (SOL), Tenure Quik (TEQ), and an experimental compound (EXP) were investigated. The adhesives were used to bond a hybrid-type resin composite to enamel and dentin. Shear bond strength (SBS) to human teeth was determined after 24-hour storage in water. The marginal performance was evaluated on restorations in 3.5 mm wide cylindrical dentin cavities as the maximum gap width found 15 minutes after light activation. The hybrid layer thicknesses at the cavity margin were measured by light microscopy.
Mean SBSs to enamel were between 23 and 35 MPa, those to dentin between 3.5 and 25 MPa. BOS and EXP showed the highest bond strengths to dentin and consistently gap-free restorations. PB2 mediated significantly lower SBS to dentin; only three of the six restorations were gap-free. SOL exhibited poor marginal quality (mean MGW 7.5 microns) despite 15 MPa dentin bond strength. PAB and TEQ demonstrated very low SBS to dentin. None of the restorations with these products was gap-free. All adhesives produced hybrid layers between 2 and 10 microns thick, as a coupling zone between dentin and restoration. Adhesives with the essential components of wetting monomer, well-polymerizing dimethacrylate, and acetone as the water-chasing solvent, performed very well when used with a moist bonding technique.
评估五种市售和一种实验性单组分釉质/牙本质粘合剂的粘结效果。
研究了粘合剂一步法（BOS）、Primabond（PAB）、Prime & Bond 2.0（PB2）、Solist（SOL）、Tenure Quik（TEQ）以及一种实验性化合物（EXP）。这些粘合剂用于将混合型树脂复合材料粘结到釉质和牙本质上。在水中储存24小时后测定对人牙的剪切粘结强度（SBS）。在3.5毫米宽的圆柱形牙本质洞中修复体的边缘性能，以光固化后15分钟发现的最大间隙宽度进行评估。通过光学显微镜测量洞边缘的混合层厚度。
对釉质的平均SBS在23至35兆帕之间，对牙本质的平均SBS在3.5至25兆帕之间。BOS和EXP对牙本质显示出最高的粘结强度，修复体始终无间隙。PB2介导的对牙本质的SBS显著较低；六个修复体中只有三个无间隙。尽管SOL对牙本质的粘结强度为15兆帕，但其边缘质量较差（平均MGW为7.5微米）。PAB和TEQ对牙本质的SBS非常低。使用这些产品的修复体无一无间隙。所有粘合剂产生的混合层厚度在2至10微米之间，作为牙本质与修复体之间的偶联区。含有湿润单体、良好聚合的二甲基丙烯酸酯和丙酮作为追水溶剂等基本成分的粘合剂，在采用湿粘结技术使用时表现非常出色。
