2021/3/17· The notion of using IP6 was proposed in 1980, where its addition to aluminosilie glass, resulted in a rapidly setting cement through an acid-base reaction. The resultant cement had low vulnerability to early attack by water and acid, as well as better adhesion to enamel compared with dentine, due to the lower mineral content of the latter ( Prosser et al., 1983 ).
