Abstract

In this study, we observed the penetration of the resin infiltrant into natural initial caries by SEM and CLSM, evaluated the pH and viscosity of resin infiltrant and several adhesives(All-bond 2, Scotchbond Multi-purpose, Clearfil SE bond), and measured the surface roughness and the microhardness on permanent teeth before and after applied resin infiltrant into initial enamel caries. The viscosity(Pa.s) was observed for resin infiltrant($0.173{\pm}0.012$), All-bond 2($0.754{\pm}0.030$), Scotchbond Multi-purpose($1.46{\pm}0.137$), and Clearfil SE bond($1.28{\pm}0.125$). The pH was measured for resin infiltrant (4.7), All-bond 2(7.5), Scotchbond Multi-purpose(8.2), and Clearfil SE bond(4.67). An application procedure of resin infiltrant increased the surface roughness and the microhardness insignificantly(p>0.05), when compared to non-applied specimens.

resin infiltrant의 초기 우식 병소에 침투를 SEM과 CLSM을 사용하여 관찰하고, resin infiltrant와 3가지 접착제(All-bond 2, Scotchbond Multi-purpose, Clearfil SE bond)의 pH와 점도를 평가하고, 영구치에 resin infiltrant 적용 후 표면 조도와 미세경도의 변화를 측정하였다. 점도(Pa.s)는 resin infiltrant($0.173{\pm}0.012$), All-bond 2($0.754{\pm}0.030$), Scotchbond Multi-purpose($1.46{\pm}0.137$), Clearfil SE bond($1.28{\pm}0.125$)로 측정되었다. pH는 resin infiltrant (4.7), All-bond 2(7.5), Scotchbond Multi-purpose(8.2), Clearfil SE bond(4.67)로 측정되었다. resin infiltrant의 적용은 적용하지 않은 시편과 비교할 때 표면 조도와 미세경도에 유의한 차이를 보이지 않았다.(p>0.05).
