Abstract

This study examined the solubility, sorption, and dimensional change of eight luting cements in two different solutions: 50% ethanol:water and distilled water. Ten disk specimens were prepared of each material following the manufacturers instructions, and then ground with silicone carbide paper. Sorption and solubility were calculated by weighing the specimens before and after immersion and desiccation. Data were analyzed by two-way ANOVA, Tukey's HSD and Fisher's PLSD tests. GC Fuji Plus and RelyX Luting2 showed the highest values of sorption and solubility both in water and ethanol:water. The percentage changes in volume for Maxcem, Nexus 2, Panavia F, RelyX Veneer, and VariolinkII were considerably smaller than for GC Fuji Plus, RelyX Luting2, and seT in both water and ethanol:water and after desiccation. Stability occurred within 2 weeks for all the eight materials when in water, while GC Fuji Plus, Maxcem, Panavia F and seT took 3 to 4 weeks to stabilize in ethanol:water.

摘要

本研究考察了八种粘接水门汀在两种不同溶液（50%乙醇:水和蒸馏水）中的溶解性、吸附性及尺寸变化。按照制造商说明为每种材料制备了10个圆盘试样，然后用碳化硅砂纸进行研磨。通过对试样浸泡和干燥前后称重来计算吸附性和溶解性。数据采用双向方差分析、Tukey's HSD检验和Fisher's PLSD检验进行分析。GC Fuji Plus和RelyX Luting2在水和乙醇:水体系中均表现出最高的吸附性和溶解性值。Maxcem、Nexus 2、Panavia F、RelyX Veneer和VariolinkII在水和乙醇:水体系中以及干燥后的体积变化百分比均显著小于GC Fuji Plus、RelyX Luting2和seT。所有八种材料在水中2周内达到稳定，而GC Fuji Plus、Maxcem、Panavia F和seT在乙醇:水体系中需要3至4周才能达到稳定。
