Abstract

OBJECTIVE

To compare the color stability of the newer glass ionomer cements (GIC) when exposed to "Green tea" (GT), "Tulsi tea" (TT), and "Areca tea" (AT) using spectrophotometric analysis.

MATERIALS AND METHODS

We selected commercially available GC Fuji IX GP EXTRA and Ketac Universal for this study. Eighty disc-shaped samples were made using a mold, which were immersed in the freshly prepared test solutions (distilled water, GT, TT, and AT) for 15 minutes per day for 60 days. The color estimation was done using a spectrophotometer.

RESULTS

GC Fuji IX samples had a significantly higher mean difference in ΔE value than Ketac Universal when immersed in GT, AT, and control (P<0.001, 0.018, and <0.001), respectively. With GC Fuji IX, GT and AT stained more than TT and control solutions. Samples of Ketac Universal showed a significantly higher mean difference in ΔE values when immersed in AT, followed by GT, TT, and control.

CONCLUSION

Within the study's limitations, we conclude that both the GICs exhibited staining over time on exposure to all the test solutions. Ketac Universal demonstrated lower staining potential than GIC Fuji IX GP Extra for GT and AT.

摘要

目的

采用分光光度法分析比较新型玻璃离子水门汀（GIC）暴露于“绿茶”（GT）、“罗勒茶”（TT）和“槟榔茶”（AT）后的颜色稳定性。

材料与方法

本研究选用市售的GC Fuji IX GP EXTRA和Ketac Universal。使用模具制作80个圆盘形样本，将其每天浸入新配制的测试溶液（蒸馏水、GT、TT和AT）中15分钟，共60天。使用分光光度计进行颜色评估。

结果

当GC Fuji IX样本浸入GT、AT和对照溶液中时，其ΔE值的平均差异分别显著高于Ketac Universal（P<0.001、0.018和<0.001）。对于GC Fuji IX，GT和AT的染色比TT和对照溶液更明显。Ketac Universal样本浸入AT后，其ΔE值的平均差异显著更高，其次是GT、TT和对照。
