Abstract Dental caries (tooth decay) is a prevalent disease. Resin composites have become the most commonly used materials to restore caries due to their direct-filling capability, tooth-colored esthetics, and photo cure-on-demand property. However, it has been reported that the current generation of composite restorations has a relatively high failure rate due to secondary caries and bulk fracture. Therefore, efforts have been made to develop a new generation of antibacterial and therapeutic dental polymeric composites to suppress caries and increase the longevity of the restorations. These new materials have demonstrated the effects to inhibit the growth of oral biofilms and plaques, reduce bacterial acid production, regenerate the lost tooth minerals, and self-heal cracks to regain the load-bearing capabilities. This article reviews the cutting-edge development for this new generation of dental restorative materials.

具有自愈裂缝和恢复机械性能的新型抗菌和治疗牙科聚合物复合材料

摘要 龋齿（蛀牙）是一种普遍的疾病。树脂复合材料由于其直接填充能力、牙齿颜色美学和按需光固化特性，已成为修复龋齿的最常用材料。然而，据报道，由于继发龋和大块断裂，当前一代复合修复体具有相对较高的故障率。因此，人们努力开发新一代抗菌和治疗牙科聚合物复合材料，以抑制龋齿并延长修复体的寿命。这些新材料已证明具有抑制口腔生物膜和牙菌斑生长、减少细菌酸产生、再生丢失的牙齿矿物质以及自愈裂缝以恢复承重能力的效果。
