All the composite resins only restoration exhibited significant microleakage, regardless of the type cavity design used. The marginal leakage was significantly reduced or eliminated in restoration where the enamel at the cavosurface angle was etched and after insertion of the restoration.
所有仅使用复合树脂的修复体均表现出明显的微渗漏，无论采用何种类型的洞型设计。在洞缘角处的釉质进行酸蚀并完成修复体就位后，修复体的边缘渗漏显著减少或消除。
