Abstract　： [ABSTRACT]The efficacy of fine Surface Pre-reacted Glass-ionomer (S-PRG) powder as a medicament for dentin hypersensitivity was evaluated by SEM, EPMA and microradiograph, Simulated hypersensitive dentin surfaces were scrubbed with the S-PRG powder (S-PRG group) and a powder of glass-ionomer cement (FAS group). The dentin surfaces of the S-PRG group were covered with powder and the dentinal tubules were completely occluded with fine particles, even after demineralization. In the FAS group, dentinal tubules were only partially occluded, and there was no powder residue in evidence at all after demineralization. EPMA analysis showed deposits of calcium, fluoride and aluminum at a higher degree in the S-PRG group. The S-PRG group indicated a significantly lower IML compared with the control (no treatment) and EAS groups. These results suggest that S-PRG powder will have a superior occluding effect on opened dentinal tubules and will provide acid resistance to the underlying dentin.
