Glass ionomer cements (GICs), restorative materials with commercial availability spanning over five decades, are widely applied due to their advantages (including bio-compatibility, fluoride release, or excellent bonding properties). However, GICs have shortcomings. Among the disadvantages limiting the application of GICs, the poor mechanical properties are the most significant. In order to enhance the mechanical or antimicrobial properties of these materials, the addition of nanomaterials represents a viable approach. The present paper aims to review the literature on the application of different types of nanomaterials for the enhancement of GICs' mechanical and antimicrobial properties, which could lead to several clinical benefits, including better physical properties and the prevention of tooth decay. After applying the described methodology, representative articles published in the time period 2011-present were selected and included in the final review, covering the modification of GICs with metallic nanoparticles (Cu, Ag), metallic and metalloid oxide nanoparticles (TiO, ZnO, MgO, AlO, ZrO, SiO), apatitic nanomaterials, and other nanomaterials or multi-component nanocomposites.
玻璃离子水门汀（GICs）作为一类已有五十多年商业应用历史的修复材料，因其具有生物相容性、氟释放能力或优异的粘结性能等优点而被广泛应用。然而，GICs也存在缺点。在限制GICs应用的诸多缺点中，较差的机械性能最为突出。为了提高这些材料的机械性能或抗菌性能，添加纳米材料是一种可行的方法。本文旨在综述不同类型纳米材料在增强GICs机械性能和抗菌性能方面的应用文献，这可能带来多种临床益处，包括更好的物理性能和预防龋齿。在应用所述方法后，选取了2011年至今发表的代表性文章纳入最终综述，内容涵盖用金属纳米颗粒（铜、银）、金属和类金属氧化物纳米颗粒（二氧化钛、氧化锌、氧化镁、氧化铝、氧化锆、二氧化硅）、磷灰石纳米材料以及其他纳米材料或多组分纳米复合材料对GICs进行改性。
