Dental resin composites (DRCs) are popular materials for repairing caries or dental defect, requiring excellent properties to cope with the complex oral environment. Filler/resin interface interaction has a significant impact on the physicochemical/biological properties and service life of DRCs. Various chemical and physical modification methods on filler/resin interface have been introduced and studied, and the physical micromechanical interlocking caused by the modification of fillers morphology and structure is a promising method. This paper firstly introduces the composition and development of DRCs, then reviews the chemical and physical modification methods of the filler/resin interface, mainly discusses the interface micromechanical interlocking structures and their enhancement mechanism for DRCs, finally give a summary on the existing problems and development potential.

牙科树脂复合材料（DRC）是修复龋齿或牙齿缺损的常用材料，需要优异的性能来应对复杂的口腔环境。填料/树脂界面相互作用对 DRC 的理化/生物特性和使用寿命有重大影响。已经介绍和研究了填料/树脂界面的各种化学和物理改性方法，由填料形态和结构的改性引起的物理微机械联锁是一种有前途的方法。本文首先介绍了DRCs的组成和发展，然后回顾了填料/树脂界面的化学和物理改性方法，主要讨论了界面微机械联锁结构及其对DRCs的增强机制，
