The aim of this article is to provide a brief insight regarding the recent studies and their recommendations related to the modifications to glass ionomer cement (GIC) powder in order to improve their properties. An electronic search of publications was made from the year 2000 to 2018. The databases included in the current study were EBSCOhost, PubMed, and ScienceDirect. The inclusion criteria for the current study include publication with abstract or full-text articles, original research, reviews or systematic reviews, in vitro, and in vivo studies that were written in English language. Among these only articles published in peer-reviewed journals were included. Articles published in other languages, with no available abstract and related to other nondentistry fields, were excluded. A detailed review of the recent materials used as a filler phase in GIC powder has revealed that not all modifications produce beneficial results. Recent work has demonstrated that modification of GIC powder with nano-particles has many beneficial effects on the properties of the material. This is due to the increase in surface area and surface energy, along with better particle distribution of the nano-particle. Therefore, more focus should be given on nano-particle having greater chemical affinity for GIC matrix as well as the tooth structure that will enhance the physicochemical properties of GIC.
本文旨在简要介绍近期有关玻璃离子水门汀（GIC）粉末改性以改善其性能的研究及其建议。对2000年至2018年的出版物进行了电子检索。本研究纳入的数据库有EBSCOhost、PubMed和ScienceDirect。本研究的纳入标准包括发表有摘要或全文的文章、原创研究、综述或系统评价、体外和体内研究，且均为英文撰写。其中仅纳入发表在同行评审期刊上的文章。排除发表在其他语言、无可用摘要且与其他非牙科领域相关的文章。对近期用作GIC粉末填充相的材料进行的详细综述表明，并非所有改性都能产生有益效果。近期研究表明，用纳米颗粒对GIC粉末进行改性对材料性能有许多有益影响。这是由于表面积和表面能的增加，以及纳米颗粒更好的颗粒分布。因此，应更多关注对GIC基质以及牙齿结构具有更大化学亲和力的纳米颗粒，这将增强GIC的物理化学性能。
