| Summary: | Introduction: The use of bleaching agents has become very
popular for whitening stained teeth. But these products if used
for extended period of time can cause various effects on the
tooth surface and restorations.
Aim: 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 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.
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 restorations.
Conclusion: 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. |
