법랑질 초기우식증의 심도에 따른 불소제제의 재광화 효과 비교

Abstract

The aim of this study was to compare the effect of remineralization with regard to the depth of early enamel carious lesions using three different fluoride agents. The specimens were prepared from the extracted bovine teeth with sound enamel surface. Artificial early enamel caries were formed using demineralization solution and severity of caries were measured as ΔF by QLF-D. According to ΔF value, the specimens were classified into two status depending on the depth of lesions; shallow and deep early enamel carious lesions. Each status was divided into four groups according to the types of fluoride agent used; control group, fluoride varnish group, fluoride tape group, and silver diamine fluoride (SDF) group. After application of each fluoride agent, the specimens were stored in artificial saliva for one week. The amount of remineralization was examined using Micro-CT and scanning electron microscope (SEM). As a results, the SDF showed the greatest remineralization effect among the three fluoride agents. The fluoride varnish and tape showed similar remineralizing effect. Only in the SDF group, a difference in the remineralization effect between shallow and deep early enamel carious lesions was observed with higher remineralization effect in deep lesion than in shallow lesion.
