This study aimed to examine the effect of beverages at different temperatures on the coloring of composites.
A total of 48 cylindrical samples, 24 of which were prepared from 2 composite materials (G'aenial; Estelite Σ Quick), were included in the study. The sample dimensions were standardized at 2 x 10 mm2. After the polishing, the initial color measurements were performed using a spectrophotometer. The samples were divided into 3 subgroups as distilled water, hot coffee (60 °C) and cold coffee (0 °C) (n=8). During the 7th and 30th days, the samples were immersed in the solutions for 15 min every day. Color measurements were repeated on the 7th and 30th days. Data were analyzed using a two-way analysis of variance, followed by the Tukey post-hoc test (p<0.05).
The highest color change was detected on the 7th and 30th days in the G-aenial anterior microhybrid composite immersed in hot coffee (p<0.001). The application of hot and cold coffee applications did not make a statistically significant difference in the coloration of the Estelite Σ Quick composite samples at the end of the 7th (p=0.346) and 30th (p=910) days.
Hot drinks had a more coloring effect on restorations. This coloration was quite evident in the microhybrid composite.
本研究旨在探讨不同温度的饮料对复合材料颜色的影响。
本研究共纳入48个圆柱形样本，其中24个由2种复合材料（G'aenial；Estelite Σ Quick）制备而成。样本尺寸标准化为2×10平方毫米。抛光后，使用分光光度计进行初始颜色测量。样本分为3个亚组，分别为蒸馏水、热咖啡（60°C）和冷咖啡（0°C）（n = 8）。在第7天和第30天，样本每天浸入溶液中15分钟。在第7天和第30天重复进行颜色测量。数据采用双向方差分析，随后进行Tukey事后检验（p<0.05）。
在第7天和第30天，浸入热咖啡中的G-aenial前牙微混合复合材料颜色变化最大（p<0.001）。在第7天（p = 0.346）和第30天（p = 0.910）结束时，热咖啡和冷咖啡对Estelite Σ Quick复合样本颜色的影响在统计学上无显著差异。
热饮对修复体的染色作用更强。这种染色在微混合复合材料中非常明显。
