초록

본 연구의 목적은 3종의 자가부식 프라이머(Clearfil SE Bond, AdheSE, Tyrian) 사용시 상아질계면의 접촉각 및 미세인장결합강도를 측정하는 것이다. 연마된 상아질 표면에 3종의 자가부식 프라이머를 각각 적용한 후 접촉각을 측정하였으며 (n=30), One-way ANOVA를 사용하여 통계처리하였다. 미세인장결합강도측정을 위해서는 상아질 표면에 3종의 자가부식 프라이머 및 상아질 접착제를 각각 적용한 후 광중합 복합레진 (Z 250)을 5mm 두께로 쌓아 올렸다. 그 후 각 시편을 결합계면에 수직으로 분할한 뒤 (n=45) universal testing machine을 사용하여 미세인장강도를 측정하였고, Kruskal-Wallis test를 통하여 통계처리하였다. 접촉각 측정결과, AdheSE, Clearfil SE Bond, Tyrian 순으로 높은 접촉각을 보였으며 각 군간 통계적 유의성 있는 차이를 보였다 (p<0.05). 미세인장결합강도 측정결과 Clearfil SE Bond군과 AdheSE군은 유의성 있는 차이를 보이지 않았으며, Tyrian군은 Clearfil SE Bond 군이나 AdheSE 군에 비해 유의성 있게 작은 미세인장결합강도를 보였다.
