Abstract


 Dentin substitute belongs to the group of cements called acid–base cements. Glass ionomer cement (GIC) was found around mid-1970 by 
Wilson and Kent. Conventional GIC is available as powder and liquid. Setting reaction of GIC is acid–base reaction. GIC has wide range 
of applications in dentistry when compared with other tooth-colored restorative cements due to its biocompatibility, cost-effectiveness and 
ability to adhere to the tooth structure without any bonding agent, anti-cariogenic property due to its fluoride releasing capacity, thermal 
compatibility with enamel and dentin, and ability to seal even in the moist environmental conditions of the mouth. In spite of all the advantages 
of conventional GIC’, certain disadvantages are lack of adequate strength and toughness, which has limited its use in high stressing bearing 
areas in posterior tooth. To overcome the problems, conventional GIC’s properties are constantly modified by reinforcing with resins, metals, 
bio-active glass, proline, chlorhexidine, zirconia, hydroxyapatite, casein phosphopeptide-amorphous calcium phosphate, and nano bioceramic 
sized glass particle, calcium aluminate, composite, condensable/self-hardening GIC, low-viscosity/flowable GIC, and fiber-reinforced GIC. 
An overview of properties, limitations, advantages, disadvantages, and various applications of these recent advances in GIC’s are discussed 
in this review article.
