树脂-牙本质粘接界面的渗透性与粘接耐久性研究进展
Research progress on the permeability of resin-dentine bonds and bonding durability

摘要： 树脂-牙本质粘接界面的渗透与树脂-牙本质粘接的耐久性密切相关。牙本质内、粘接剂中以及冲洗残留的水分和外界环境中的水分是树脂-牙本质粘接界面纳米级渗漏区水的重要来源，而纳米级渗漏区的存在会降低树脂-牙本质粘接界面的粘接性能和粘接的耐久性。降低牙本质小管内液体渗透性和增强粘接剂对混合层的渗透能力，可提高树脂-牙本质粘接界面的粘接力和耐久性。本文就牙本质的液体渗透性、粘接树脂的渗透性以及改善渗透提高粘接力和粘接耐久性策略等研究进展作一综述，以期为今后进一步的理论研究和临床应用有所作为。
Abstract: The permeability of resin-dentine bonds is closely related to the mechanical stability of resin-dentine bonds and bonding durability. Water from dentinal tubules, contained in the adhesives or remained after etching and rinsing, together with water from the outside environment are sources of water in the areas of nanoleakage, which leads to decreased resin-dentine bonds. Two aspects related to permeability are thought to improve the mechanical stability of resindentine bonds. One aspect is the reduction of permeability in the dentinal tubules, and the other is the improvement of resin infiltration to the hybrid layer. This review includes the permeability of dentine, infiltration of adhesives in the hybrid layer, and strategies concerning permeability and infiltration to create stable resin-dentine bonds.
