The aim of this chapter is to provide information on the different types of glass-ionomer cements available and the unique properties of this group of materials.

Readers will better comprehend how the composition and setting reaction of glass-ionomer cement dictates its handling to optimise clinical performance, including fluoride release, bond strength and dimensional stability.

Glass-ionomer cement was first made commercially available in 1976 as a self-adhesive, tooth-coloured filling material called ASPA. It derived its name as an acronym of the major constituents, aluminosilicate glass and polyacrylic acid. The early materials were slow-setting and difficult to handle, with relatively poor aesthetics. Subsequently, there have been major...
