Glass ionomers are used frequently due to the versatile properties they contain and the relative ease with which they can be used. GIC has multiple advantages: First, it adheres specifically to the teeth to prevent corrosion or leakage. 4. Glass Ionomer Cements – Glass ionomer cements are formed when a glass powder is mixed with an aqueous solution of polyacrylic acid. Glass ionomer cement is a kind of dental cement that was developed in 1965 and began to be used in restorative dentistry in 1972. Made of a silicate glass powder combined with a water-soluble polymer, these cements are also called \"giomers.\" They are used to permanently cement dental inlays, bridges, crowns and orthodontic brackets and to fill cavities.
