Abstract： 背景:许多学者在改进复合树脂和粘接剂的性能进行了大量的实验工作,但仍不能完全消除复合树脂充填体材料与牙体之间的微渗漏,微渗漏是影响牙体修复远期疗效的上要障碍之一.目的:观察Fortify Light-Cured表皿封闭剂减少复合树脂修复体边缘微渗漏的作用.设计、时间及地点:对比观察实验,于2008-01/08在解放军四五八医院口腔科完成.材料:选择因正畸拔除的前磨牙45个,在每个牙齿的颊血颈部分别制洞,大小为3 mm×3 mm×2 mm的长椭圆形窝洞,窝洞颌壁位于釉质,颈壁位于牙骨质.Fortify Light-Cured表面封闭剂为美国Bisco公司产品.方法:将实验牙随机分为3组:表面封闭剂组、粘结剂组、空白对照组,15颗/组.表面封闭剂组:用可乐丽菲露SE BOND牙质粘合用处理剂处理20 s,中弱气流彻底于燥,涂布粘接剂,光照射10 s,可乐丽菲露复合树脂允填,光照40 s,调磨抛光后,牙质粘合用处理剂处理牙一树脂充填体表面,中弱气流彻底十燥,均匀涂布表面封闭剂,光照20 s.粘结剂组:与表面封闭剂组处理方式相同,粘接剂均匀涂布代膂表面封闭剂.空白对照组:也以同样的方式处理但调磨抛光后,将所有实验牙置于37℃生理盐水24 h备用.主要观察指标:体式显微镜下测量染料渗入洞壁的深度,扫而电镜下观察树脂与牙体组织粘结面的情况.结果:复合树脂充填修复后使用表面封闭剂、粘接剂封闭充填体表面,边缘微渗漏明显减少.Kruskal-Wallis检验对3组树脂进行比较,差异均有显著性(P<0.05).各组内冠侧壁与龈壁侧相比,冠侧壁略低于龈侧壁,但差异无显著性(P>0.05).扫描电镜下观察可见,表面封闭剂组:树脂与牙体组织结合良好;粘结剂组:树脂与牙体组织间出现裂隙;空白对照组:树脂与牙体组织间出现裂隙,裂隙较粘结剂组明显.结论:使用表而封闭剂可减少微渗漏的程度.
