This study was designed to assess the effect of two bleaching agents on the disintegration tendency of three types of glass ionomers.
A total of 90 specimens were prepared by using a split Teflon ring with an internal diameter of 5 mm and a thickness of 2 mm. The tested materials were applied and bleached according to manufacturer's instructions. Dissolution measurements were made by calculating weight loss through different periods of the test; (one week, one month and three months) and they were analyzed by using one-way analysis of variance (ANOVA), followed by Tukey's post-hoc test.
All glass ionomer materials exhibited a degree of dissolution. Opalescence Xtra increased the dissolution of Photac Fil and F2000 significantly, while Opalescence Quick had no effect on dissolution of glass ionomer restoratives.
Bleaching effect on dissolution of glass ionomers is material and time dependant. Care should be taken by clinicians When bleaching teeth that are restored by glass ionomer, because this dissolution may affect the physical properties of these restorations.
本研究旨在评估两种漂白剂对三种类型玻璃离子水门汀崩解趋势的影响。
使用内径5毫米、厚度2毫米的分体式聚四氟乙烯环制备了总共90个样本。按照制造商的说明应用并漂白测试材料。通过计算测试不同时间段（一周、一个月和三个月）的重量损失来进行溶解测量，并使用单因素方差分析（ANOVA）进行分析，随后进行Tukey事后检验。
所有玻璃离子水门汀材料均呈现出一定程度的溶解。Xtra Opalescence显著增加了Photac Fil和F2000的溶解，而Opalescence Quick对玻璃离子修复材料的溶解没有影响。
漂白对玻璃离子水门汀溶解的影响取决于材料和时间。临床医生在对用玻璃离子水门汀修复的牙齿进行漂白时应谨慎，因为这种溶解可能会影响这些修复体的物理性能。
