| 摘 要： | 本文采用不同的酸蚀涂布压力处理牙釉质面,通过SEM作结构观察并作TBS测试,结果表明施加轻压力时牙釉质表面结构完整,测试的粘接强度高,而施加重压力时破坏了牙釉质表面结构,粘接强度下降.以上结果为提高临床粘接效果提供了重要数据.

| Abstract: | In this paper the Scanning Electric Microscope observation and bond strength test to enamel acid-etched with various coating pressure were carried out. The results showed that the surface structure of enamel was intact and its tensile bond strength was high when low pressure was applied, while the surface structure of enamel was destroyed and the tensile bond strength was low in case of high pressure was used. The findings are significant to improve bond effects in clinic. |
