Note (General): We evaluated the effect of hydroxyapatite (HAp) incorporated into resin-modified glass ionomer cement (RMGIC). Commercial RMGIC (Fuji II LC; GC, Tokyo, Japan) was used as a control (GIC-LC) and the base material of the AIC group (AIC-LC). The AIC-LC powder contained 88 wt% Fuji II LC glass powder and 12 wt% spherical-shaped hydroxyapatite powder with an average particle size of 20 μm. The AIC-LC specimens were created by mixing the AIC-LC powder and Fuji II LC liquid with the same powder to liquid ratio as that of the GIC-LC specimens. The flexural strength and flexural modulus as well as the dose releases of fluoride and other mineral ions were evaluated in this study. No significant differences in the flexural strength or modulus were noted between GIC-LC and AIC-LC. The dose of fluoride ion released from the AIC-LC specimens was significantly greater than that from the GIC-LC. In addition, the doses of Al, Si, Ca, and Sr released from AIC-LC were also significantly greater than those from GIC-LC. We concluded that adding porous spherical-shaped HAp to RMGIC is effective for improving the function of RMGIC in the prevention and remineralization of dental caries.
