Abstract

This study was designed to evaluate the effectiveness of 5% sodium fluoride-polyvinyl alcohol (NaF-PVA) tape influencing enamel remineralization by analysing enamel surface microhardness (SMH) and variation of ${\Delta}F$ of QLF. After enamel demineralizing of specimen, these 60 specimens with average KHN of microhardness ranging from 50 to 100 and with ${\Delta}F$ of QLF ranging from -15 to -25 were divided into four groups : group 1 (control group), group 2 (NaF-PVA), group 3 (fluoride varnish, FluoroDose$^{(R)}$ varnish), group 4 (Casein phosphopeptide-amorphous calcium phosphate, Tooth mousse plus$^{TM}$). These specimens were treated with materials and then immersed in artificial saliva. We measured remineralization rate each using surface microhardness (SMH) and Quantitative light-induced fluorescence digital (QLF-D). As a result, NaF-PVA tape is better than group 1, 4 and have comparable remineralization effect with group 3 (p < 0.05).

이 논문은 법랑질의 표면미세경도와 QLF의 ${\Delta}F$ 값의 변화를 분석하여 5% 불화나트륨을 함유한 고분자 접착 테잎(NaF-PVA)이 법랑질의 재광화에 미치는 영향을 평가하고자하였다. 시편을 탈회한 후 표면미세경도가 평균 50-100 KHN의 범위를 갖고 QLF의 ${\Delta}F$ 값이 -25에서 -15 범위를 갖는 60개의 시편들을 4그룹으로 나누었다 : 그룹1(대조군), 그룹2(NaF-PVA), 그룹3(불소바니쉬, FluoroDose$^{(R)}$ varnish), 그룹4(Casein phosphopeptide-amorphous calcium phosphate, Tooth mousse plus$^{TM}$). 시편들에 각 제제들을 적용하고 인공타액(artificial saliva)에 담근 후 표면미세경도계와 정량 광 형광기를 이용하여 재광화율을 측정하였다. 그 결과 불소를 함유한 고분자 접착 테잎(NaF-PVA)은 그룹1과 4보다 뛰어나며 그룹3과 견줄만한 재광화 효과를 나타냈다 (p<0.05).
