摘要

Introduction: This study was designed to assess the effect of two bleaching agents on the disintegration tendency of three types of glass ionomers.Materials and Methods: A total of 90 specimens were prepared by using a split Teflon ring with an internal diameter of 5mm and a thickness of 2mm. 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.Results: 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.ConclusionBleaching 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.
