Abstract

OBJECTIVE

To compare the effect of Green, Tulsi, and Areca teas on the color stability of two composite materials on the 30th and 60th days.

MATERIALS AND METHODS

Two light cure composite restorative materials, Brilliant EverGlow (Group 1) and Brilliant NG, (Group 2) with different resin and filler characteristics were selected. The test solutions selected were Green tea, Tulsi tea, Areca tea, and artificial saliva (control group). In total, 104-disc shaped specimens were fabricated using a custom made brass mold as per the manufacturer instructions. All specimens were put in storage for rehydration and complete polymerization at 37°C in distilled water for 24 hours. Specimens of each composite material were randomly divided into four subgroups of 13 samples. Tea solutions were freshly prepared, and specimens were immersed in the respective solutions every day for 15 minutes for 60 days. Specimens were stored in artificial saliva after the immersion regimen. The color evaluation was done before immersion, on the 30th and 60th day, using a digital reflectance spectrophotometer.

RESULTS

At 30 days, Group 1 specimens immersed in Areca and Green teas showed significantly higher mean values than those in control and Tulsi tea. At 60 days in Group 1, specimens in Areca tea showed significantly higher mean value, followed by Green tea, Tulsi tea, and control. At 30 and 60 days in group 2, specimens in control had significantly lower mean values than other tea preparations. Group 1 showed a higher mean difference in ΔE than Group 2 specimens immersed in Green and Areca teas at 30 days (P=0.001 and 0.001) and 60 days (P=0.001 and <0.001), respectively.

CONCLUSION

All herbal tea preparations exhibited staining potential, which increased over time, and Areca tea showed the highest staining potential. Understanding the staining potential of newer tea preparations on recent composite materials helps the clinician to choose the right restorative materials.

摘要

目的

比较绿茶、罗勒茶和槟榔茶对两种复合材料在第30天和第60天时颜色稳定性的影响。

材料与方法

选择两种具有不同树脂和填料特性的光固化复合修复材料，即Brilliant EverGlow（第1组）和Brilliant NG（第2组）。所选的测试溶液为绿茶、罗勒茶、槟榔茶和人工唾液（对照组）。根据制造商说明，使用定制的黄铜模具总共制作了104个圆盘形标本。所有标本在37°C的蒸馏水中储存24小时以进行再水化和完全聚合。每种复合材料的标本随机分为四个亚组，每组13个样本。茶溶液每天新鲜制备，标本每天在各自溶液中浸泡15分钟，共60天。浸泡方案结束后，标本储存在人工唾液中。使用数字反射分光光度计在浸泡前、第30天和第60天进行颜色评估。

结果

在第30天，浸泡在槟榔茶和绿茶中的第1组标本的平均值显著高于对照组和罗勒茶中的标本。在第1组的第60天，槟榔茶中的标本平均值显著更高，其次是绿茶、罗勒茶和对照组。在第2组的第30天和第60天，对照组标本的平均值显著低于其他茶制剂。在第30天（P = 0.001和0.001）和第60天（P = 0.001和<0.001），第1组在ΔE方面的平均差异高于浸泡在绿茶和槟榔茶中的第2组标本。
