渗透性树脂对树脂修复体微渗漏影响的实验观察

Experimental Investigation into the Effect of the Infiltration Resin to Save the Microleakage between Restorations and Cavity

目的:观察使用渗透性树脂ICON对修复体边缘进行处理后的微渗漏变化。方法:20颗健康离体牙随机分为2组,颊面制备深度2mm的窝洞,Z350树脂充填,A组使用渗透性树脂ICON处理树脂修复体边缘处的牙体组织及树脂牙体结合处,B组为对照组。37℃水浴条件下分别置于0.1%罗丹明B荧光染料浸染,24h后激光扫描共聚焦显微镜测量染液渗入深度,定量评价微渗漏程度,对检测结果进行统计学分析。结果:A、B组微渗漏差异有统计学意义(P<0.05)。结论:渗透性树脂对改善树脂修复体微渗漏状况有明显效果。

Objective： To compare the effect on the microleakage of two methods whether treated with infiltration resign or not to fill the cavity in vitro.Methods： 20 extracted teeth were divided into two groups（A and B） randomly.The cavity at the buccal surface were filled with resign（Z350）.Group A,the tooth near the resin restoration and the junction of tooth and resin restoration,were treated with ICON,while group B was the control group.To evaluate the microleakage after 0.1% rhodamine water bath at 37℃.Results： The method with the treatment of the infiltration resign was better on the microleakage than another group（P〈0.05）.Conclusion： The infiltration resign had clear effect on saving microleakage.
