| 摘 要： | 目的制备新型的可见光固化牙本质粘结剂,并对其性能进行研究。方法以Bis-GMA和4-META为主要成分,分别选用HEMA和TEGDMA为稀释单体,制备了两种可见光固化牙本质粘结剂,测试了其剪切粘结强度,并对其粘结表面进行了SEM观察。结果以HEMA为稀释单体的粘结剂和以TEGDMA为稀释单体的粘结剂平均剪切粘结强度分别为21.8MPa和7.54MPa,且SEM结果显示含HEMA的粘结剂能更好地渗入牙本质小管中形成树脂突。结论以HEMA为稀释单体的粘结剂具有更好的粘结性能。说明HE-MA在牙本质粘结剂中扮演着非常重要的角色,能极大地改善材料的粘结性能。

| Abstract: | Objective To study new visible light cured dentin adhesives.Methods Bis-GMA and 4-META were chosen as matrixes to develop two kinds of new visible light cured dentin adhesives with different diluents.The shear bonding strength was tested and bonding surfaces were observed under the scan electrical microscope(SEM).Results The average shear bonding strength of the two adhesives with HEMA and TEGDMA were 21.8MPa and 7.54MPa respectively,and the SEM results showed that the adhesives containing HEMA was much eas... |
