Abstract

This study compared the microtensile bond strength $({\mu}TBS)$ of three single step adhesives to dentin. Occlusal superficial dentin was exposed in fifteen human molars. They were assigned to three groups by used adhesives: Xeno group (Xeno III). Prompt group (Adper Prompt L-Pop). AQ group (AQ Bond). Each adhesive was applied to dentin surface. and composite of same manufacturer was constructed. The bonded specimens were sectioned into sticks with an interface area approximately $1mm^2$, and subjected to $\mu$ TBS testing with a crosshead speed of 1mm/minute. The results of this study were as follows; 1. The ${\mu}TBS$ to dentin was $48.78\pm9.83MPa$ for Xeno III. $30.22\pm4.52MPa$ for Adper Prompt L-Pop. and $26.31\pm7.07MPa$ for AQ Bond. 2. The mean ${\mu}TBS$ of Xeno group was significantly higher than that of Prompt group and AQ group (p<0.05). 3. There was no significant difference between the ${\mu}TBS$ of Prompt group and AQ group.

본 연구는 상아질에 대한 3종의 단일 단계 접착제의 미세인장 결합강도를 상호 비교하였다 15개의 발거된 상$\cdot$하악 대구치의 교합면측에 있는 표층 상아질을 노출시킨 후, 사용된 접착제에 따라 3개의 군 (Xeno군-Xeno III, Prompt군-Adper Prompt L-Pop, AQ군-AQ Bond)으로 분류하여 복합레진을 축조하였다. 각 시편을 막대모양으로 제작하였고, 각 군 당 20개의 시편을 이용하여 미세인장 결합강도를 측정하여 다음과 같은 결과를 얻었다. 1 상아질에 대한 각 군의 미세인장 결합강도는 Xeno군에서 $48.78\pm 9.83MPa$, Prompt군에서 $30.22\pm4.52MPa$, AQ군에서 $26.31\pm7.07MPa$로 나타났다. 2.Xeno 군은 Prompt 군과 AQ 군보다 통계학적으로 높은 미세인장 결합강도를 나타냈다 (p<0.05). 3. Prompt 군과 AQ 군의 미세인장 결합강도 간에는 통계학적으로 유의차가 없었다 (p>0.05).
