Outline of Final Research Achievements |
This study indicated that the novel teeth coating material and the novel resin-based temporary filling material which contained S-PRG filler had remineralization and anti-demineralization effects on dentin in vitro. S-PRG filler could release various types of ions, including fluoride, strontium, sodium, boron, aluminum and silicate ions. However, in situ investigation, daily use of fluoride-containing dentifrice diminished the effect of the materials on root dentin demineralization. Further, among the subjects of lower saliva flow rate, the materials could not bring out the anti-demineralization effects. We would like to establish the system which induces hyper-remineralization on subsurface dentin lesions for even these patients.
