초록

본 연구는 간접 복합 레진 인레이 수복 시 기저재로 사용되는 광중합형 글래스아이오노머와 인레이 접착에 사용되는 레진 시멘트간의 접착 전까지의 시간 경과에 따른 전단 결합강도를 측정하고, 상아질과 글래스아이오노머, 글래스아이오노머와 레진 시멘트간 접착계면에 대해 SEM 관찰하였다. 2종의 광중합형 글래스아이오노머 시멘트 Fuji Ⅱ LC (GC Co, Tokyo, Japan)와 VitrebondTM (3M, Paul, Minnesota, U.S.A)의 시편을 제작하였다. 5 ㎜ X 7 ㎜의 실리콘 주형에 ArtglassⓇ (Heraeus Kultzer, Germany)를 이용하여 레진 인레이를 제작하였다. 글래스아이오노머 베이스를 각 각 1시간, 24시간, 1주 및 2주 동안 37℃ 증류수에 보관한 후 VariolinkⓇ Ⅱ (Ivoclar Vivadent, Liechtenstein)를 적용하여 인레이를 접착하였다. 만능 물성시험기(Model 4302, Instron, U.S.A)를 이용하여 결합면에 1 ㎜/min의 속도로 1000 ㎏ 하중을 가하여 전단 결합강도를 측정하였고, one-way ANOVA를 이용하여 통계 분석하였다. SEM 관찰을 위해 발거된 제 3대구치에 2급 와동을 형성하였고, 기저재로 광중합형 글래스아이오노머 시멘트를 적용하였다. 인레이를 접착한 시편을 수직 절단하여 상아질, 글래스아이오노머, 및 복합레진 인레이 간의 계면을 SEM (JSM-5400Ⓡ Jeol, ToKyo, Japan) 관찰하였다. 시간 경과에 따른 글래스아이오노머와 복합 레진 인레이 사이의 전단 결합강도는 통계학적으로 유의한 차이가 없었으며, 기저재 재료에 따른 전단 결합강도의 유의한 차이도 없었으며 대부분 시편에서 글라스아이오노머 내부에서 응집 파괴 (Cohesive failure)가 발생하였다. SEM 관찰 시 글래스아이오노머와 상아질 사이에 약 30-120㎛ 정도의 간극(gap)이 형성되었으며, 글래스아이오노머와 복합 레진 인레이 계면에서는 1시간 후 접착한 시편을 제외하고 간극은 발견되지 않았다.

Abstract

This study was done to evaluate the shear bond strength between light-cured glass ionomer cement (GIC) base and resin cement for luting indirect resin inlay and to observe bonding aspects which is produced at the interface between them by SEM. Two types of light cured GIC (Fuji Ⅱ LC Improved, GC Co. Tokyo, Japan and VitrebondTM, 3M, Paul, Minnesota, U.S.A) were used in this study. For shear bond test, GIC specimens were made and immersed in 37℃ distilled water for 1 hour, 24 hours, 1 week and 2 weeks. Eighty resin inlays were prepared with Artglass (Heraeus Kultzer, Germany) and luted with Variolink Ⅱ (Ivoclar Vivadent, Liechtenstein). Shear bond strength of each specimen was measured and fractured surface were examined. Statistical analysis was done with one-way ANOVA. Twenty four extracted human third molars were selected and Class Ⅱ cavities were prepared and GIC based at axiopulpal lineangle. The specimens were immersed in 37℃ distilled water for 1 hour, 24 hours, 1 week and 2 weeks. And then the resin inlays were luted to prepared teeth. The specimens were sectioned vertically with low speed saw. The bonding aspect of the specimens were observed by SEM (JSM-5400, Jeol, ToKyo, Japan). There was no significant difference between the shear bond strength according to storage periods of light cured GIC base. And cohesive failure was mostly appeared in GIC. On scanning electron micrograph, about 30 - 120 ㎛ of the gaps were observed on the interface between GIC base and dentin. No gaps were observed on the interface between GIC and resin inlay.
