Abstract

The aim of this study was to evaluate the effect of temporary restorative and filling material on bonding strength between lithium disilicate glass-ceramic and dentin. 60 extracted human molars were cross-sectioned at occlusal third and were embedded into self-cure acrylic resin. Then the teeth were randomly divided into four groups of 15 each. Lithium disilicate glass-ceramic is cemented to dentin as follows: after no any application of the provisional materials (Group A), after application of ALIKETM (GC America Inc.)(Group B), after application of Luxatemp$^{(R)}$ Automix plus (DMG, Germany)(Group C), after application of Fermit$^{(R)}$ (Ivoclar Vivadent, Leichtenstein)(Group D). After the specimens were stored in distilled water for 24 hours, the shear bond strength of the specimens were measured using UTM (Zwick 1456 41, Zwick, Germany) at a crosshead speed of 1mm/min. The data were analysed by one-way ANOVA and Tukey HSD tests. There were no statistically significant differences of bond strength among the groups. Fracture type was showed mixed type of adhesive and cohesive fracture in most of specimens. Within the limitation of this study, bond strength of adhesive resin cement between lithium disilicate glass-ceramic and dentin was not affected by provisional restorative and filling materials.

본 연구는 lithium disilicate glass-ceramic과 상아질 간의 결합력에 대한 임시 수복재와 임시 충전재의 효과를 평가하기 위함이 목적이었다. 60개의 발치된 치아를 자가중합형 레진에 포매한 후 교합1/3 부위를 절단하였고, 무작위로 15개씩 4그룹으로 나누었다. 그런 후 lithium disilicate glass-ceramic을 다음과 같이 그룹으로 나누어 상아질에 접착시켰다: 아무 처리도 하지 않은 그룹(그룹A), ALIKETM (GC America Inc.)를 적용한 그룹(그룹 B), Luxatemp$^{(R)}$ Automix plus (DMG, Germany)를 적용한 그룹(그룹 C), Fermit$^{(R)}$ (Ivoclar Vivadent, Leichtenstein)를 적용한 그룹(그룹 D). 모든 시편들을 24시간 증류수에 담가 보관한 후, 1 mm/min의 crosshead speed로 만능시험기(Zwick 1456 41, Zwick, Germany) 상에서 전단 결합 강도를 측정하였다. 모든 그룹 간에 결합력의 통계학적 유의성은 없었으며, 파절양상은 대부분 시편에서 접착성(adhesive)과 응집성(cohesive)이 복합적으로 보이는 혼합형(mixed type)을 보였다. 본 실험의 제한된 조건 하에서는 임상에서 lithium disilicate glass-ceramic을 상아질에 접착시, 임시 수복재나 임시 충전재의 영향이 그리 크지 않을 것으로 판단되었다.
