ALL—BOND 2粘结材料处理后的牙本质壁与充填体间密合情况观察

The observation of the adaptation between Amalgam restorations and dental walls treated by ALL - Bond 2 adhesive

通过对ALL—BOND2粘结材料处理的窝洞内壁与银汞充填物间的密合情况进行观察,以评价其在充填治疗中的意义。应用染料渗入法和扫描电镜技术。结果表明,实验组充填体边缘微漏率明显低于洞壁未加处理的对照组(P<0.01)。结论:ALL—BOND粘结材料能够明显改善充填体边缘微漏。

To observe the adaptation of amalgam dental restoration and cavity walls treated by ALL-Bond 2 adhesive and to evaluate the application significance of the adhesive chinic. Method:dye penetration method and electron scanning microscopy- Results:The rate of marginal microleakage in experimental group was significally lower than that in the control. Conclude: ALL - Bond 2 adhesive could prevent the marginal microleakage of amalgam restoration obviously.
