摘　　要：目的研究氧化锌丁香油对3种永久粘固剂与牙本质间粘结强度的影响。方法将因正畸需要拔除的60颗前磨牙制成试样块并用树脂包埋,一面暴露作为测试面,去除其釉质暴露浅层牙本质并用砂纸磨平。分为玻璃离子组(Ⅰ组)、树脂改性玻璃离子体组(Ⅱ组)、树脂粘结剂组(Ⅲ组),然后各组再分为对照组(A组),氧化锌丁香油组(B组),每组10个试样。在万能试验机上测试4 mm直径树脂块在A、B两种条件下用3种永久粘结剂粘固后的剪切强度。并用扫描显微镜观察剪切后试样表面形貌。结果 3组受氧化锌丁香油影响较大((3.22±1.47)MPa对比(1.22±0.35)MPa,P=0.001),1组、2组在A、B两种条件下剪切强度差异无统计学意义(P>0.05)。结论使用氧化锌丁香油粘固剂预处理牙本质表面,对树脂类粘固剂有不利影响,而对玻璃离子和树脂改性玻璃离子体无不利影响。Objective To investigate the influence of zinc oxide eugenol（ ZOE） on shear bond strength of three kinds of permanent cement when bonded to dentin. Methods The 60 premolars were made into test pieces and embedded with resin. One side was exposed as a test surface,with its enamel removed and superficial dentin polished with sandpaper. Specimens were divided into glass ionomer group（ group 1）,a resin-modified glass ionomer group（ group 2）,and a resin binder group（ group 3）. Each group was further divided into a control group（ group A）,and ZOE group（ group B）,each group containing 10 samples. Specimens with resin blocks（ φ4 mm） were tested in the universal testing machine. And surface morphology was observed with a scanning microscope. Results Group 3 was influenced by zinc oxide eugenol（（ 3. 22 ± 1. 47） MPa vs.（ 1. 22 ± 0. 35） MPa,P = 0. 001）,while group1 and 2were not. Conclusion Pre-treatment of the dentin with ZOE temporary cement has an adverse effect on the resin cement but not on the glass ionomer and resin-modified glass ionomer.
