Abstract
[한글] 저자는 현재 국내에 시판중인 2종류의 glass ionomer cement, 즉 Shofu Glass Ionomer Base **(R) 와 GC Dentin Cement **(R) 을 대상으로 37% 인산을 사용하여 0초, 15초, 30초, 60초로 산부식 시간을 달리한 후 미세입자형 광중합형 복합레진인 Silux **(R) 를 결 합시킨 후 Instron testing machine을 사용하여 결합력을 측정한 결과 다음과 같은 결론을 얻었다. 1. 산부식 시간에따라 glass ionomer cement과 복합레진과의 결합력에 있어서 변화가 있었다. 2. Shofu glass ionomer cement에서 제3군에서는 즉 30초간 산부식처리시 가장 강한 결합력을 보였으며 제1군 즉 산부식하지 않은 군과 비교시 통계학적으로 유의성이 있었다. (p<0.05) 3. GC glass ionomer cement에서는 제4군에서 즉 60초간 산부식 처리시 가장 강한 결합력을 보였으며 제1군 즉 산부식하지 않은 군과 비교시 통계학적으로 유의성이 있었다. (p<0.05)
[영문] The purpose of this study was to evaluate the effects of various etching time that affect to the bending strength between glass ionomer cement and composite resin. Two glass ionomer cements were divided into 4 groups according to 4 various etching time each other. Total 80 specimens were uniformly made and tested for the bonding strength between glass ionomer cement and composite resin by Instron. The seperation forte was recorded from the composite resin to the glass ionomer cement block for each specimens. The results were as follows : 1. Etching time affects the bonding strength between glass ionomer cement and composite resin. 2. In Shofu g1ass ionomer cements the 3 group, 30sec etching group was greater than any other groups and significant differences were statistically demonstrated when compared to the 1 group non-etching group.(P<0.05) 3. In GC glass ionomer cement, the 4 goup, 60sec etching group, was greater than any other groups and significant differences were statistically demonstrated when compared to the 1 group, non-etching group.(p<0.05)
