Two adhesives, Super Bond and Panavia, were evaluated for shear bond strength to dentin. Twenty human teeth were used for each adhesive. Bonding sites were prepared in dentin (600 grit) and the adhesives applied according to the manufacturers' instructions. Bond strengths were determined with an Instron testing machine at 24 hours. Super Bond developed the strongest bond of 21.59 +/- 3.91 MPa. Panavia produced a lower bond strength of 2.68 +/- 1.45 MPa. Statistically, Super Bond was found to have a stronger bond than Panavia. The same two adhesives were applied to Ni-Cr-Be specimens and compared to Comspan. Twenty Rexillium III specimens were used for each adhesive at 24 hours and 20 for thermocycling. The metal specimens were ground flat (600 grit) and then air abraded with 50-micron aluminous oxide. The adhesives were applied to the metal surface in accordance with the manufacturers' instructions. One group was tested at 24 hours while the second group was tested after thermocycling (2,500 cycles at 6 degrees C to 60 degrees C). At 24 hours, Super Bond had a significantly stronger bond than the other materials. Comparison of the 24-hour to thermocycled bond strengths found Comspan had a significant increase in bond strength, Panavia had no significant change and Super Bond had a significant decrease in bond strength. After 2,500 thermocycles, Comspan, Panavia, and Super Bond were not significantly different in bond strength.
对两种粘结剂Super Bond和Panavia进行了与牙本质的剪切粘结强度评估。每种粘结剂使用20颗人牙。在牙本质（600目砂纸）上制备粘结部位，并按照制造商的说明应用粘结剂。在24小时时用Instron试验机测定粘结强度。Super Bond的粘结强度最强，为21.59±3.91兆帕。Panavia的粘结强度较低，为2.68±1.45兆帕。统计学上，发现Super Bond的粘结力比Panavia更强。将相同的两种粘结剂应用于镍铬铍合金试件，并与Comspan进行比较。每种粘结剂在24小时时使用20个Rexillium III试件，热循环时使用20个。将金属试件磨平（600目砂纸），然后用50微米的氧化铝进行空气喷砂处理。按照制造商的说明将粘结剂应用于金属表面。一组在24小时时进行测试，而第二组在热循环后（在6摄氏度至60摄氏度之间循环2500次）进行测试。在24小时时，Super Bond的粘结力明显强于其他材料。比较24小时和热循环后的粘结强度发现，Comspan的粘结强度显著增加，Panavia没有显著变化，Super Bond的粘结强度显著降低。经过2500次热循环后，Comspan、Panavia和Super Bond的粘结强度没有显著差异。
