Abstract

OBJECTIVE

To evaluate and compare the water sorption of three luting cements in three different solutions: distilled water and artificial saliva with different pH values (7.4 and 3.0).

MATERIALS AND METHODS

Resin-modified glass-ionomer cement (GC Fuji Plus) and two resin cements (Multilink Automix and Variolink II) were used. A total of 45 specimens - 15 specimens (15x1 mm) for each cement were prepared according to ISO standard 4049:2009. The water sorptions of the cements were calculated by weighing the specimens before and after immersion and desiccation.

RESULTS

. Nonparametric statistic methods were applied. GC Fuji Plus cement showed significantly higher values of water sorption in all three solutions of both resin cements (p<0.009) and significantly higher values of sorption in artificial saliva pH 3.0. Multilink Automix showed significantly higher values of water sorption compared with Variolink II in artificial saliva pH 7.4, and higher values of sorption in this solution compared with pH value 3.0.

CONCLUSION

Water sorption values are mainly influenced by the proportion of hydrophilic matrix, the type and composition of filler, and the pH value of solutions.

摘要

目的

评估并比较三种粘结水门汀在三种不同溶液中的吸水率：蒸馏水以及不同pH值（7.4和3.0）的人工唾液。

材料与方法

使用树脂改性玻璃离子水门汀（GC Fuji Plus）和两种树脂水门汀（Multilink Automix和Variolink II）。根据ISO标准4049:2009制备总共45个样本——每种水门汀制备15个样本（15×1毫米）。通过对样本浸泡和干燥前后称重来计算水门汀的吸水率。

结果

采用非参数统计方法。GC Fuji Plus水门汀在两种树脂水门汀的所有三种溶液中的吸水率均显著更高（p<0.009），且在pH值为3.0的人工唾液中的吸附值显著更高。在pH值为7.4的人工唾液中，Multilink Automix的吸水率显著高于Variolink II，且在该溶液中的吸附值高于pH值为3.0时的吸附值。
