| Outline of Final Research Achievements |
This study examined the effect of a fluoride-releasing sealer containing surface reaction-type prereacted glass-ionomer (S-PRG) filler on dentin demineralization using optical coherence tomography (OCT) and ultrasonic measurement.Although there were no significant changes in signal intensity and width at 1/e2 in the Control group, significant changes were observed in the S-PRG group during the first test period. Sonic velocity was found to increase with S-PRG group compared with control group.
By using optical coherence tomography (OCT) and ultrasonic measurement, it can be concluded that the fluoride-releasing sealer containing S-PRG fillers sealer has an ability to promote bovine dentin remineralization.
