From clinical standpoint, glass ionomer cements appear to be beneficial because of their release of fluoride. However, these cements do not show any chemical bone- bonding ability which makes them liable to degrade over a certain period of time. Extensive attempts have been previously made to obtain bioactive cements. It has also been reported that CaO(MgO)-SiO2-P2O5 glasses possess superior bioactivity by forming apatite layer on the surface of glass both in vivo and in vitro. In our previous studies, we have investigated the effects of the bioactive glass addition to resin- modified glass ionomer cement on its setting time, setting characteristics, and compressive strength. The present study is aimed at examining the possibility of obtaining bioactive resin- modified glass ionomer cements wherein apatite formation of cements after immersion in the synthetic body fluid were investigated.
