Tooth discoloration is considered as one of the most common dental problems among people, and in dentistry, the most common cases are claimed after the restoration. Therefore, in this research, we aim to evaluate the effect of carbonated beverages on the color stability of bulk and flowable composite resin. For the study, 12 composite disc samples were made using the standard dimensions of 10 mm diameter and 2 mm thick. To find the color stability, we used a VITA Easyshade spectrophotometer. We used two different composites of bulk fill and flowable composite resin; the composite brand we used was Tetric ecom plus; as an immersion medium, we used two different carbonated beverages, and the chosen beverages were Appy Fizz and 7Up. 24-h and 7-day postimmersion color stability was evaluated. In the results of postimmersion, we have found the Delta E value for 24 h immersion of flowable and bulk fill composite as 5.8115 and 7.4378, respectively; similarly, the Delta E value for 7 days immersion of flowable and bulk fill composite was 9.9559 and 10.1028, respectively. Using the independent "t"-test, we found that the significance is 0.633 and 0.328, which was statistically not significant. In the present study, when immersed in Appy Fizz juice and 7Up juice, bulk fill composite resins have shown greater discoloration when compared to flowable composite resin material. Thus, the flowable composite resin samples were more color stable.
牙齿变色被认为是人们中最常见的牙科问题之一，在牙科领域，最常见的情况是在修复后出现。因此，在本研究中，我们旨在评估碳酸饮料对块状和可流动复合树脂颜色稳定性的影响。在该研究中，使用直径10毫米、厚2毫米的标准尺寸制作了12个复合圆盘样本。为了确定颜色稳定性，我们使用了VITA Easyshade分光光度计。我们使用了两种不同的复合材料，即块状填充和可流动复合树脂；我们使用的复合品牌是Tetric ecom plus；作为浸泡介质，我们使用了两种不同的碳酸饮料，所选饮料为Appy Fizz和七喜。评估了浸泡后24小时和7天的颜色稳定性。在浸泡后的结果中，我们发现可流动和块状填充复合材料浸泡24小时的ΔE值分别为5.8115和7.4378；同样，可流动和块状填充复合材料浸泡7天的ΔE值分别为9.9559和10.1028。使用独立t检验，我们发现显著性分别为0.633和0.328，在统计学上不显著。在本研究中，当浸泡在Appy Fizz果汁和七喜果汁中时，与可流动复合树脂材料相比，块状填充复合树脂显示出更大的变色。因此，可流动复合树脂样本的颜色更稳定。
