Dental resin composites (DRCs) are popular materials to repair caries. Although various types of DRCs with different characteristics have been developed, restoration failures still exist. Bulk fracture and secondary caries have been considered as main causes for the failure of composites restoration. To address these problems, various fillers with specific functions have been introduced and studied. Some fillers with specific morphologies such as whisker, fiber, and nanotube, have been used to increase the mechanical properties of DRCs, and other fillers releasing ions such as Ag, Ca, and F, have been used to inhibit the secondary caries. These functional fillers are helpful to improve the performances and lifespan of DRCs. In this article, we firstly introduce the composition and development of DRCs, then review and discuss the functional fillers classified according to their roles in the DRCs, finally give a summary on the current research and predict the trend of future development.
牙科树脂复合材料（DRCs）是修复龋齿的常用材料。尽管已经开发出了具有不同特性的各种类型的DRCs，但修复失败的情况仍然存在。大块断裂和继发龋被认为是复合材料修复失败的主要原因。为了解决这些问题，已经引入并研究了具有特定功能的各种填料。一些具有特定形态的填料，如晶须、纤维和纳米管，已被用于提高DRCs的机械性能，而其他释放银、钙和氟等离子的填料则被用于抑制继发龋。这些功能性填料有助于提高DRCs的性能和使用寿命。在本文中，我们首先介绍DRCs的组成和发展，然后回顾并讨论根据其在DRCs中的作用分类的功能性填料，最后对当前的研究进行总结并预测未来的发展趋势。
