AIM

This study aimed to assess the color stability of bioactive restorative materials vs nanohybrid resin composites after 3 months of immersion in three frequently consumed beverages.

MATERIALS AND METHODS

Thirty disk-shaped specimens of Giomer dental restorative material (Shofu, Japan) and nanohybrid resin composite (Tokuyama, Japan) were performed using a Teflon mold. Super-Snap system (Shofu, Japan) was utilized to finish and polish the specimens to be preserved for 24 hours in distilled water at 37°C. The samples had been divided into three subgroups (Coffee, tea, Pepsi) ( = 5). The initially displayed color measurements of the samples were performed using a spectrophotometer (VITA Easyshade® V). After 7 days, 30 days, and 90 days, color measurements were repeated, and the of each sample was estimated. of each sample was calculated.

RESULTS

The Giomer group showed statistically significant higher values than the nanohybrid resin composite where the -value was ≤0.0001. Tea subgroup showed the highest statistically significant values in both groups where the -value was ≤ 0.0001. The highest statistically significant color change was recorded at 3 months.

CONCLUSION

The color of bioactive restorative material is less stable if compared with nanohybrid resin composite.

CLINICAL SIGNIFICANCE

As tea and coffee are popular beverages, particularly in Middle Eastern nations, dentists must advise patients about the color change of resin restorations. Patients are advised to brush their teeth immediately after consuming these beverages. How to cite this article: Saber EH, Abielhassan MH, Abed YA, .

目的

本研究旨在评估生物活性修复材料与纳米复合树脂复合材料在浸泡于三种常见饮料 3 个月后的颜色稳定性。

材料与方法

使用聚四氟乙烯模具制作 30 个 Giomer 牙科修复材料（Shofu，日本）和纳米复合树脂复合材料（Tokuyama，日本）的圆盘状试件。使用 Super-Snap 系统（Shofu，日本）对试件进行修整和抛光，然后在 37°C 的蒸馏水中保存 24 小时。将样本分为三组（咖啡、茶、百事可乐）（每组 5 个）。使用分光光度计（VITA Easyshade® V）对样品的初始显示颜色进行测量。在第 7 天、第 30 天和第 90 天重复进行颜色测量，并评估每个样本的。计算每个样本的。

结果

Giomer 组的值明显高于纳米复合树脂复合材料，＜0.0001。两组中，茶组的值均具有统计学显著意义，＜0.0001。两组中，在 3 个月时记录到的颜色变化最大。

结论

与纳米复合树脂复合材料相比，生物活性修复材料的颜色稳定性较差。

临床意义

由于茶和咖啡是受欢迎的饮料，特别是在中东国家，牙医必须告知患者有关树脂修复体颜色变化的情况。建议患者在饮用这些饮料后立即刷牙。如何引用本文：Saber EH、Abielhassan MH、Abed YA、。生物活性修复材料与纳米复合树脂复合材料的颜色稳定性：一项研究。当代牙科实践 2024；25（3）：221-225。
