Class-lonomer cements: a critical review

Recently, there has been a considerable interest in the clinical application of glass-ionomer cements. Some of the inherent physical and chemical properties make the glass-ionomer cements excellent dental restorative materials in selected clinical situations. These include the slow release of fluoride, which may produce an anticariogenic action, physicochemical bonding to enamel and dentin, reducing the need for retentive cavity preparation and biocompatibility with pulpal tissue. The introduction of faster setting and metal-reinforced glass-ionomer has exp and ed their application in restorative dentistry
