大多数微渗漏研究涉及定量示踪剂分子通过修复材料和洞壁之间的缝隙的移动的大小。本显微镜研究考察了硝酸银在牙本质和五种不同的牙本质粘结剂之间的迁移，这些粘结剂用于修复5类龋齿，在没有间隙形成的情况下。观察到了几种不同的渗漏模式，但通过扫描电子显微镜观察，这些渗漏图案都表明杂化层存在渗漏。微渗漏从最多到最少的顺序是：All-Bond 2>；Suberond C&B>；Scotchond多用途>；Clearfi Liner Bond System>；Kuraray实验系统，KB-200。为了区分这种特殊类型的微渗漏，在杂化层的基础上，在没有形成间隙的情况下，我们提出了纳米渗漏这一术语。
Most microleakage studies involve quantitating the magnitude of movement of a tracer molecule through a gap between restorative materials and the wall of cavity preparations. The present microscopic study examined the migration of silver nitrate into the interface between dentin and five different dentin bonding agents used to restore class 5 cavities, in the absence of gap formation. Several different leakage patterns were seen, but they all indicated leakage within the hybrid layer when viewed by SEM. The ranking of microleakage from most to least was: All-Bond 2 > Suberbond C&B > Scotchbond Multi-Purpose > Clearfil Liner Bond System > Kuraray Experimental System, KB-200. To distinguish this special type of microleakage within the basal, porous region of the hybrid layer in the absence of gap formation, we propose the term nanoleakage.
