Since these glass ionomer-resin cements (GIRC) have been developed recently, investigation of their physical properties is necessary before recommending clinical usage. The first purpose of this project was to investigate the influence of powder/liquid ratio and storage temperature of the cement liquid on the setting time of two GIRC.And the second purpose was to determine the influence of P/L ratio on the temperature change during setting phase. And the final purpose was to determine the influence of static load during setting on physical properties and dentin bond strength.GIRCs used were Fuji Lute (GC) and Vitremer luting cement (3M).Fuji I (GC) and Bistite ResinCement (TOKUYAMA) were used as controls.The result were as follows :1. The setting time of the GIRCs showed a tendency to increase as the P/L ratio of the cementdecreased. This tendency was more pronounced for Vitremer Luting Cement than Fuji Lute.2. The storage temperature of the cement liquid had little effect on the setting time of thecements.3. Gradual temperature rise was recorded the beginning of the measurement for Vitremer luringcement and Fuji I, follower by gradual decrease in temperature.The time when the temperatureremained at its peak was longer than Fuji Lute and Bistite Resin Cement.4. A rapid temperature rise was recorded from the beginning of the measurement for Fuji Lute and Bistite Resin Cement, followed by decreasing temperature after reaching its peak. The time when the temperature remained at its peak was shorter than Vitremer luting cement and fuji 1.On the other hand, beginning of the measurment for Vitremer luting cement and Fuji 1, followed by gradual decrease in temperature. The time when the temperature remained at its peak was longer than Fuji lute and Bistite Resin CemenHigher temperature was recorded with increasing P/L ratio for all GIRCs tested.5. Physical properties and dentin bond strength of GIRCs were significantly increased with increasing static load during setting.

由于这些玻璃离子树脂水泥（GIRC）是最近开发的，在推荐临床使用之前，有必要对其物理性能进行研究。本课题的主要目的是研究粉液比和水泥浆贮存温度对两种GIRC凝结时间的影响，以及粉液比对凝结阶段温度变化的影响。本研究采用Fuji Lute（GC）和Vitremer luting cement（3 M）作为GIRCs，Fuji I（GC）和Bistite ResinCement（TOKUYAMA）作为对照，研究静态载荷对牙本质物理性能和粘结强度的影响。随着水泥P/L比的减小，GIRCs的凝结时间有增加的趋势。Vitremer Luting骨水泥的这一趋势比Fuji Lute.2更明显。水泥液的贮存温度对水泥的凝结时间影响不大. Vitremer水泥和Fuji I水泥在测量开始时温度逐渐升高，随后温度逐渐降低，温度达到峰值的时间比Fuji Lute和Bistite树脂水泥长. Fuji Lute和Bistite树脂骨水泥从测量开始记录了快速温度升高，然后在达到峰值后降低温度。温度保持在峰值的时间短于Vitremer骨水泥和Fuji 1。另一方面，Vitremer骨水泥和Fuji 1的测量开始后，温度逐渐下降。温度保持在峰值的时间比Fuji lute和Bistite Resin Cement长，随着P/L比的增加，所有GIRCs的温度都升高.随着静载荷的增加，GIRCs的物理性能和牙本质粘结强度显著增加。
