Abstract
본 연구의 목적은 우상치에서 법랑질의 산부식 효과를 Quantitative light-induced fluorescence (QLF)를 사용하여 정량적으로 평가하는 것이다.
30개의 발거된 소의 절치를 사용하였다. 치근을 잘라낸 치관부 치아만을 1000ml 생리식염수 병뚜꼉에 매몰하였다. 치관의 절반을 #400-Grit SiC paper로 삭제하고. 나머지 절반은 삭제하지 않았다. 각 표면에 투명한 네일바니쉬를 도포하여 3×3 mm 크기의 enamel window를 형성하였다. 총 120개의 window를 형성하여 무작위로 20개씩 6개 그룹으로 나누어 15, 30, 60초간 32% 인산을 적용한 후 수세, 건조하여 QLF와 FE-SEM분석을 시행하였다.
QLF 분석결과, 15초, 30초간 산부식한 그룹에서, 법랑질 표면을 삭제한 그룹이 삭제하지 않은 그룹보다 유의적으로 높은 형광소실도를 보였다. 60초간 산부식한 그룹에서는, 표면삭제유무에 따른 유의적인 차이는 존재하지 않았다. 법랑질 표면을 삭제한 그룹과 삭제하지 않은 그룹 모두에서, 15초 산부식은 60초 산부식보다 유의적으로 낮은 형광소실도를 나타내었다. 그러나 15초와 30초, 30초와 60초 산부식 그룹간에 유의적인 차이는 존재하지 않았다. FE-SEM 분석결과, 산부식시간이 증가할수록 법랑소주의 노출이 증가하였으며, 표면삭제한 군은 삭제하지 않은군보다 더 균일한 표면을 보였다.
본 연구에서 다양한 산부식 시간과 삭제유무에 따른 법랑질 산부식 효과를 QLF를 이용해서 정량적으로 평가할 수 있었다.
