In this preliminary study the degree of marginal leakage was assessed for different cavity designs using both ultra violet-curing and self-curing composite restorative materials and sealants. Butt joint restorations placed in etched and sealant primed cavities failed to prevent leakage. Both saucer-shaped and funnel-shaped cavities and cavities with rounded margins were able to prevent leakage when the restorations were bonded to etched and sealant primed peripheral enamel. Further, less than 1 mm of gingival enamel available for bonding seemed to be sufficient in most instances to prevent leakage.
在这项初步研究中，使用紫外线固化和自固化复合修复材料及封闭剂，对不同窝洞设计的边缘渗漏程度进行了评估。置于酸蚀并涂有封闭剂底漆的窝洞中的对接修复未能防止渗漏。当修复体粘结到酸蚀并涂有封闭剂底漆的周边釉质上时，碟形和漏斗形窝洞以及边缘呈圆形的窝洞都能够防止渗漏。此外，在大多数情况下，可用于粘结的龈侧釉质少于1毫米似乎足以防止渗漏。
