To evaluate the effects of three fresh detox juices, including an orange, green, and red beverage, on the color stability and surface roughness of three anterior esthetic resin-based composites (RBCs).
Disk-shaped specimens were prepared with three different esthetic RBCs (Amaris, G-aenial Anterior, Clearfil Majesty ES-2) according to the manufacturers' instructions. Forty specimens were prepared for each RBC, and all specimens were stored in artificial saliva at 37°C for 24 hours. The initial color values and surface roughness measurements of the specimens were taken using a spectrophotometer and a profilometer. The specimens were then divided into 4 subgroups (n = 10). All specimens except the control specimens were immersed in their designated fresh detox juices (green, red, or orange) for 10 minutes twice a day. Color and surface roughness measurements were taken on day 15 and day 30, and the results were analyzed by one-way ANOVA and Tukey HSD test. The association between color change and surface roughness was evaluated by Spearman's Rank Correlation analysis.
Color changes and surface roughness increased upon exposure to fresh detox juices for 15 and 30 days for all of the RBCs. All of the G-aenial and Amaris groups displayed color changes above the threshold of acceptability, whereas Clearfil Majesty ES-2 displayed a color change above the threshold of acceptability only after exposure to the red beverage for 30 days (ΔE > 3.7). With regard to surface roughness, Clearfil Majesty ES-2 outperformed the other RBCs (p < 0.001). According to Spearman's Rank Correlation analysis, there was no correlation between color change and surface roughness (p > 0.001).
Exposure to the fresh detox juices used in this study led to similar color changes in the RBCs used in this study.
评估三种新鲜排毒果汁（包括一种橙色、绿色和红色饮料）对三种前牙美学树脂基复合材料（RBC）颜色稳定性和表面粗糙度的影响。
根据制造商的说明，用三种不同的美学 RBC（Amaris、G-aenial Anterior、Clearfil Majesty ES-2）制备圆盘状试件。每个 RBC 制备 40 个试件，所有试件均在 37°C 的人工唾液中储存 24 小时。使用分光光度计和轮廓仪测量试件的初始颜色值和表面粗糙度。然后将试件分为 4 组（n=10）。除对照组试件外，所有试件均每天两次将其浸入指定的新鲜排毒果汁（绿色、红色或橙色）中 10 分钟。在第 15 天和第 30 天测量颜色和表面粗糙度，并通过单因素方差分析和 Tukey HSD 检验对结果进行分析。通过 Spearman 秩相关分析评估颜色变化与表面粗糙度之间的关系。
所有 RBC 在暴露于新鲜排毒果汁 15 和 30 天后，颜色变化和表面粗糙度均增加。所有 G-aenial 和 Amaris 组的颜色变化均超过可接受性阈值，而 Clearfil Majesty ES-2 仅在暴露于红色饮料 30 天后才显示出超过可接受性阈值的颜色变化（ΔE>3.7）。就表面粗糙度而言，Clearfil Majesty ES-2 优于其他 RBC（p<0.001）。根据 Spearman 秩相关分析，颜色变化与表面粗糙度之间没有相关性（p>0.001）。
本研究中使用的新鲜排毒果汁暴露导致研究中使用的 RBC 发生相似的颜色变化。
