As defined by Kenneth J Annusavice, ‘Glass Ionomer’ is the generic name of a group of materials that use silicate glass powder and aqueous solution of polyacrylic acid. Glass ionomer cements are among the most widely used dental cements for various modes of treatment. They are water based cements that form strong bonds with the tooth structure without the necessity for adhesive substances. They are used for various purposes ranging from cavity lining, cavity restorations, long term luting of fixed prostheses, sealing pits and fissures, fixing orthodontic brackets and has various other applications in dentistry. According to the ISO terminology they are called ‘poly alkenoate cements’.

History of GIC:

In the year 1965, A.D Wilson mixed silicate glass powders and aqueous solutions of various organic acids. This included the use of polyacrylic acid too. But the set cement that resulted was sluggish. This material was neither reported nor published. However, in 1969, Glass Ionomer cements were invented and in 1971 were reported by Wilson and Kent (ASPA I). In 1972, an amended version of the original glass ionomer was done by Crisp and Wilson. This included the addition of tartaric acid (ASPA II). Further changes included the addition of methyl alcohol (ASPA III). The first marketable glass ionomer material came out in the year 1973.
