| Outline of Final Research Achievements |
Effects of a fluoride-releasing varnish on dentin demineralization were examined using optical coherence tomography (OCT). Bovine incisors that were sliced and treated with undersaturated 0.1 M lactic acid buffer solution (DE group). A thin film of varnish was applied before demineralization (Coated group). Control was maintained in artificial saliva. Using OCT of selected locations on the dentin surface, peak intensity (dB) and width (μm) at 1/e2 were obtained and integrated values calculated. Although alterations in integrated values were different in each group, there was a slight but not significant increase in those for the control group and a slight but significant increase for the De group. For the Coated group, integrated values were doubled seven days after experiment initiation, followed by a significant increase. Fluoride-releasing varnish prevented dentin demineralization as detected by optical coherence tomography.
