用复合树脂充填牙本质窝洞时,如先用牙本质粘结剂处理洞壁可减小边缘微漏的宽度和频度。本文作者在以前实验中采用Gluma粘结剂(一种10％戊二醛和35％β-羟乙基甲基丙烯酸酯的混合液)使复合树脂和牙本质之间的结合强度达到了17.65MPa。虽然这是目前最有效的粘结剂,但它尚不能完全避免边缘微漏的形成。作者指出,牙本 Filling dentin cavities with a composite resin, such as treating denticles with dentin, reduces the width and frequency of marginal microleakage. In the previous experiment, the author used Gluma binder (a mixture of 10% glutaraldehyde and 35% β-hydroxyethyl methacrylate) to achieve a bonding strength between the composite resin and dentin of 17.65 MPa . Although this is by far the most effective binder, it still can not completely avoid edge microleakage. The authors point out that dentin
