We investigated the effect of resinous temporary material on the tensile bond strength of resin luting cement to enamel and to dentin. Four hundred bovine incisor teeth were randomly divided into groups. Four resinous temporary materials and four resin luting cements were used. On enamel, none of the resinous temporary materials decreased the tensile bond strength of the cements. On dentin, all the resinous temporary materials decreased the tensile bond strength of the cements except one containing 4-META/MMA-TBB.
我们研究了树脂类临时材料对树脂粘结水门汀与牙釉质和牙本质之间拉伸粘结强度的影响。400颗牛切牙被随机分组。使用了四种树脂类临时材料和四种树脂粘结水门汀。在牙釉质上，没有一种树脂类临时材料降低水门汀的拉伸粘结强度。在牙本质上，除了一种含4-META/MMA-TBB的树脂类临时材料外，所有树脂类临时材料均降低了水门汀的拉伸粘结强度。
