Clinical use of glass ionomer cement: a literature review

Class ionomer cement (GIC) was first introduced to clinical dentistry by Wilson and Kent in 1972. GIC has undergone continuous development designed to take advantage of the material’s unique characteristics. GIC’s tissue compatibility, fluoride release, and chemical union with underlying tooth tissue explain the wide variety for its clinical uses. Classification of the different types of GIC, ranging from luting, lining, restorative esthetics and reinforced varieties, suggests valuable potential uses in restorative dentistry. GIC has been recognized by pediatric dentists as well suited to preventive dentistry demands. The advantages of using GIC include its adhesion to underlying tooth tissue and fluoride release. However, a reservation on GIC use is its lack of fracture strength which may be surmounted in the foreseeable future. Satisfactory esthetic result can be produced with the new version of GIC but it is generally less pleasing than that with composite resin. It must be noted that GIC, like any other restorative dental materials, requires proper handling and attention to details during clinical application
