Sol –gel-derived bioactive glass nanoparticle-incorporated glass ionomer cement with or without chitosan for enhanced mechanical and biomineralization properties

Glass ionomer cement (GIC) is a tooth-colored material introduced by Wilson and Kent [1] in the late 1960s. GIC is set based on a reaction between a fluoroaluminosilicate-based glass powder and an acidic liquid primarily composed of polyacrylic acid. These substances bond chemically to the tooth structure via a carboxyl (from GIC)-calcium (from enamel or dentin) interaction and release fluoride ions for a relatively long period, which is a beneficial anticariogenic property [2,3]. Along with the above advantages, GIC has been used as luting cement, a restorative material or a base and liner before a final direct or indirect restoration.
