グラスアイオノマーセメント（GIC）は、生体活性を有する主流の修復材料であり、歯の裏張り、接着、封鎖、合着、修復などの幅広い用途がある。GICsの歯科における幅広い用途のための大きな特徴は、歯質への接着性、フッ化物放出能力、歯の色をした修復物であるが、水分に対する感度、固有の不透明性、長期的な摩耗性、強度などは望まれるほど十分ではない。これらの材料は，金属イオンや樹脂成分の添加など組成の変化が著しく，それによって物性が改善され，臨床応用性の高い修復材料として用途が多様化している。光硬化型ポリマー補強材は，フッ素徐放性と接着性の利点を維持しつつ，実質的な利点があると思われる。接着性やフッ素徐放性などの本来の性質を変えることなく、強度や審美性などの特性を向上させるために、さらなる研究が必要である。

Glass-ionomer cements (GICs) are mainstream restorative materials that are bioactive and have a wide range of uses, such as lining, bonding, sealing, luting or restoring a tooth. Although the major characteristics of GICs for the wider applications in dentistry are adhesion to tooth structure, fluoride releasing capacity and tooth-colored restorations, the sensitivity to moisture, inherent opacity, long-term wear and strength are not as adequate as desired. They have undergone remarkable changes in their composition, such as the addition of metallic ions or resin components to their composition, which contributed to improve their physical properties and diversified their use as a restorative material of great clinical applicability. The light-cured polymer reinforced materials appear to have substantial benefits, while retaining the advantages of fluoride release and adhesion. Further research should be directed towards improving the properties, such as strength and esthetics without altering its inherent qualities, such as adhesion and fluoride releasing capabilities.
