Abstract

The aim of this study was to evaluate the bonding ability of two self etch systems to human primary and permanent enamel and the effect of additional acid etching time. Exfoliated, caries free human primary molar(n=65) and permanent molar extracted (n=65) were used. prepared enamel specimens were randomly divided into 2 test groups and a control group. The control group(n=10) were treated with 35% phosphoric acid gel and Scotchbond Multi-purpose adhesive. Experimental groups(self-etching systems) were subdivided into 6 groups(each n=10) according to additional etching time(0s, 5s, 10s, 15s, 20s, 30s). The result were as follows : 1) The shear bond strengths of the self-etching adhesives(Clearfil SE Bond, Adper Prompt L-pop) without additional etching were lower than control group(Scotch Bond Multipurpose). 2) Between the same self-etch adhesive groups, additional etched groups showed higher shear bond strength 3) There was no significant difference between primary and permanent enamel. In conclusion, bond strength of self-etch adhesives to enamel could be increased with additional etching.

이 연구의 목적은 유치와 영구치의 법랑질에 자가 산부식 접착제 적용 전 부가적인 산부식 시간을 달리 하였을 때, 전단결합강도에 미치는 영향을 알아보기 위함이다. 각각 65개의 발거된 건전한 유치와 영구치 협, 설면 법랑질 시편을 제작하고 두 종류의 자가 산부식 접착제를 적용하였다. 실험군은 $Clearfil^{TM}$ SE bond, $Adper^{TM}$ $Prompt^{TM}$ $L-pop^{TM}$으로 처리한 두 개 군으로 나누고, 이를 다시 산부식 시간에 따라 여섯 군(0, 5, 10, 15, 20, 30초)으로 분류하였다. 대조군으로는 total-etching system인 $Adper^{TM}$ $Scotchbond^{TM}$ Multi-purpose plus를 사용하였다. 접착제 처리면을 복합레진으로 충전하고 24시간 경과 후 전단결합강도를 측정하고 Mann-Whitney test와 Kruskal-Wallis test를 사용하여 통계분석 하였다. 결과는 자가 산부식 접착제를 적용한 군은 유치, 영구치 모두에서 total etching system에 비해 낮은 전단 결합강도를 보였다. 자가 산부식 접착제 사용 군내에서 산부식을 추가로 시행하였을 때 유치와 영구치 모두에서 결합강도가 증가하였으며, 10초 이상 산부식을 시행한 경우 결합력의 차이는 없는 것으로 나타났다. 유치와 영구치간 결합력의 차이는 인정되지 않았다. 결론적으로, 자가 산부식 접착제의 법랑질에 대한 전단결합강도는 유치, 영구치 모두에서 10초 이상의 부가적 산부식이 결합력의 증가에 유리하게 작용하는 것으로 나타났다.
