The degrees of marginal leakage was tested for different restorative techniques with use of both ultraviolet-polymerized and cold-curing resins. All the materials tested showed severe marginal leakage when applied as conventional butt joint restorations. When the restorations were extended onto peripheral etched enamel, either with or without a sealant-primed etched surface, marginal leakage was prevented in most instances with both the cold-curing and ultraviolet-polymerized materials. However, the ultraviolet-polymerized sealant was more effective in preventing marginal leakage than the cold-curing sealants when applied as a covering over the restorations and extended onto the peripheral etched enamel.
使用紫外线聚合树脂和冷固化树脂，对不同修复技术的边缘微渗漏程度进行了测试。所有测试材料在作为传统对接接头修复体应用时均显示出严重的边缘微渗漏。当修复体延伸至周边蚀刻釉质时，无论有无密封剂预处理的蚀刻表面，冷固化材料和紫外线聚合材料在大多数情况下都能防止边缘微渗漏。然而，当作为修复体的覆盖物并延伸至周边蚀刻釉质上应用时，紫外线聚合密封剂在防止边缘微渗漏方面比冷固化密封剂更有效。
