本研究的目的是评估树脂复合材料粘合系统在不同固化模式下对有或没有唾液污染的牙齿的即时剪切粘合强度。测定树脂复合粘合剂的努氏硬度值。使用了树脂复合材料粘合系统的四种组合。在不同储存期间、不同固化模式下测量有和没有唾液污染的情况下对牛牙齿的剪切粘合强度。还评价了树脂复合粘合剂的努普硬度值。无论固化模式或唾液污染如何，在所有树脂复合材料粘合系统中，5 分钟与 24 小时相比，牙釉质和牙本质剪切粘合强度和努普硬度数值均显着降低。树脂复合材料粘合系统的固化模式对剪切粘合强度和努普硬度值的影响取决于材料。对于唾液污染条件，无论固化方式、储存期或牙基质如何，只有 G-CEM ONE EM 在有和没有唾液污染的组之间没有显示出任何显着的剪切粘合强度差异。所有树脂复合材料粘合系统在凝固后立即表现出较低的剪切粘合强度和努氏硬度值。
The purpose of this study was to evaluate the immediate shear bond strength of resin composite luting systems to tooth with or without saliva contamination in different curing modes. The Knoop hardness number of the resin composite luting agents was measured. Four combinations of resin composite luting systems were used. The shear bond strength to bovine teeth was measured with and without saliva contamination in different curing modes at different storage periods. The Knoop hardness number of the resin composite luting agents was also evaluated. Significantly lower enamel and dentin shear bond strengths and Knoop hardness number values were observed in all resin composite luting systems at 5 min versus 24 h, regardless of the curing mode or saliva contamination. The influence of the curing mode of the resin composite luting systems on shear bond strengths and Knoop hardness number was dependent on material. For the saliva contamination conditions, only G‐CEM ONE EM did not show any significant difference in shear bond strength among the groups with and without saliva contamination, regardless of curing mode, storage period, or tooth substrate. All the resin composite luting systems showed lower shear bond strengths and Knoop hardness number values immediately after setting.
