摘要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.
