What is the primary use of glass ionomer cement (GIC) in dental procedures?

Glass ionomer cement (GIC) is primarily used in dental procedures for its ability to bond chemically with both enamel and dentin, which makes it particularly suitable as a permanent filling material. Its unique composition allows it to release fluoride, providing additional protection against caries and promoting remineralization of the affected tooth structure.

This material is often favored for certain types of restorations, especially in areas that are subject to less stress, such as in primary teeth or as undercuts in larger composite restorations. The adhesive properties of GIC, combined with its biocompatibility and aesthetic qualities, make it a versatile choice for various restorative needs.

In contrast, although other materials might be utilized in temporary cavity linings or as bonding agents, these purposes do not fully leverage the chemical bonding and protective features that glass ionomer cement offers as a permanent solution.
