纳米填料在减少牙科复合树脂微渗漏中的作用以前没有研究过。因此，本研究旨在评价纳米填充复合树脂的微渗漏与传统的杂化复合材料相比。选择20个拔除的完好磨牙。制备II类洞。用37%的磷酸蚀刻所有的牙洞（牙釉质和牙本质）。将牙本质粘结剂应用于蚀刻的牙齿表面，并使用纳米填充和混合复合修复材料进行修复。修复后的牙齿进行热循环。将样本浸入2%亚甲蓝染料中，沿近中-远中方向沿着切片;使用立体显微镜评估每个切片的咬合和牙龈边缘的染料渗透。纳米填充和混合型复合材料充填体在咬合/釉质和牙龈/牙本质边缘的微渗漏之间无显著差异。此外，在咬合/釉质边缘和牙龈/牙本质边缘的纳米填充复合材料的覆盖没有显著差异。另一方面，在咬合/釉质边缘和牙龈/牙本质边缘处，混合复合材料的弯曲度有显著差异。
The role of nanofillers in reducing the microleakage of dental composite resins has not been previously investigated. So this study was designed to evaluate microleakage of nanofilled composite resin in comparison to the conventional hybrid composite. Twenty extracted sound molars were selected. Class II cavities were prepared. All cavities were etched (enamel and dentin) with 37% phosphoric acid. Dentin bonding agents were applied to etched tooth surfaces and restored with nanofilled and hybrid composite restorative materials. The restored teeth were thermocycled. Specimens were immersed in 2% methylene blue dye, sectioned along the mesio-distal direction; dye penetration of occlusal and gingival margins of each section was evaluated using a stereo-microscope. No significant difference was found between the microleakage of nanofilled and hybrid composite restorations at occlusal / enamel and at gingival / dentin margins. Also, there were no significant differences for nanofilled composite restorations at occlusal / enamel margins and gingival / dentin margins. On the other hand, there were a significant differences for hybrid composite restorations at occlusal / enamel margins and gingival / dentin margins.
