This investigation evaluated the shear rebond strength of Rexillium III to enamel using various resin composite luting systems (Panavia, Imperva Dual, ABC Enhanced, C&B Metabond, Optibond, and Comspan). Cast Rexillium III cylinders (3.9 x 6.0 mm) were bonded to human molar buccal enamel surfaces (n = 8) with each cement type after etching with 37% phosphoric acid for 30 seconds. Bonded specimens were stored in distilled water for 7 days at 37 degrees C +/- 2 degrees C and thermocycled (1,500 cycles) in 5 degrees C and 55 degrees C water baths (1 minute dwell time). Specimens were randomly tested in shear mode on an Instron Testing Machine at a crosshead speed of 0.5 mm per minute. Debonded specimens were then rebonded after appropriate metal conditioning and re-etching the enamel surface for 30 seconds. Analysis of variance (P < 0.001) and the Ryan-Einot-Gabriel-Welsh multiple range test showed significant differences between several of the resin cements (P < 0.05). Panavia exhibited significantly higher shear rebond strength than any of the other cements tested. Only Imperva Dual exhibited a significantly lower shear rebond strength compared to its initial shear bond strength.
本研究使用多种树脂复合材料粘结系统（Panavia、Imperva Dual、ABC Enhanced、C&B Metabond、Optibond和Comspan）评估了Rexillium III与牙釉质之间的剪切再粘结强度。将铸造的Rexillium III圆柱体（3.9×6.0毫米）用37%磷酸蚀刻30秒后，用每种粘结剂粘结到人类磨牙颊面牙釉质表面（n = 8）。粘结后的标本在37℃±2℃的蒸馏水中储存7天，并在5℃和55℃的水浴中进行热循环（1500次循环）（停留时间1分钟）。标本在Instron测试机上以每分钟0.5毫米的十字头速度随机进行剪切模式测试。脱粘后的标本在进行适当的金属预处理并将牙釉质表面重新蚀刻30秒后进行再粘结。方差分析（P < 0.001）和Ryan-Einot-Gabriel-Welsh多重范围检验显示，几种树脂粘结剂之间存在显著差异（P < 0.05）。Panavia表现出比任何其他测试粘结剂都显著更高的剪切再粘结强度。与初始剪切粘结强度相比，只有Imperva Dual表现出显著更低的剪切再粘结强度。
