To evaluate and compare the water sorption and water solubility of four self-etching, self-adhesive resin luting agents.
Four self-etching, self-adhesive resin luting agents (RelyX Unicem, Maxcem, Biscem, Multilink Sprint) and one classic resin luting agent (Multilink Automix) as a control group were used. Twelve disks (8 mm x 1 mm) of each material were prepared according to ISO 4049. Water sorption and solubility were calculated, using the formulae which the ISO 4049 specification provides.
Maxcem and Biscem were found to have very high water sorption values. RelyX Unicem and Multilink Sprint exhibited water sorption values only slightly higher than the control group. Regarding water solubility, the greater mass loss was found for Maxcem. Multilink Sprint exhibited no mass change. Biscem was found to have low solubility values, whereas RelyX Unicem and Multilink Automix exhibited negative solubility.
Multilink Sprint and RelyX Unicem were found to comply with the ISO requirements regarding water sorption and solubility, while Maxcem and Biscem did not. Materials of the same group exhibited very different behavior during their interaction with water.
评估和比较 4 种自酸蚀、自粘接树脂水门汀的吸水和水溶性能。
使用 4 种自酸蚀、自粘接树脂水门汀（RelyX Unicem、Maxcem、Biscem、Multilink Sprint）和 1 种经典树脂水门汀（Multilink Automix）作为对照组。根据 ISO 4049 标准制备每种材料的 12 个圆盘（8mm×1mm）。采用 ISO 4049 规范提供的公式计算吸水率和溶解度。
Maxcem 和 Biscem 的吸水率非常高。RelyX Unicem 和 Multilink Sprint 的吸水率仅略高于对照组。就溶解度而言，Maxcem 的质量损失最大。Multilink Sprint 没有质量变化。Biscem 的溶解度值较低，而 RelyX Unicem 和 Multilink Automix 的溶解度值为负值。
Multilink Sprint 和 RelyX Unicem 的吸水率和溶解度符合 ISO 要求，而 Maxcem 和 Biscem 不符合。同一组的材料在与水相互作用时表现出非常不同的行为。
