| Research Abstract |
This study evaluated the effect of pre-reacted glass-ionomer (PRG) filler extraction solution on demineralization of bovine enamel by measuring changes in the ultrasound transmission velocity. No changes in sonic velocity were found for specimens stored in the PRG filler extraction solution, indicating that the PRG extraction solution had an effect on inhibiting the demineralization of bovine enamel. Within the limitations of this in vitro study, it can be concluded that the S-PRG filler extraction solution has an ability to prevent demineralization of the enamel. Released ions such as Al, BO, Si, Sr, the S-PRG fillers might improve the acid resistance of teeth.
