This investigation was carried out to evaluate the color stability of a nanocomposite restorative material and the erosive potential of carbonated soft drinks (Coca-Cola; The Coca-Cola Company, Atlanta, Georgia, United States) and packaged orange juice (Real Fruit Power Orange; Dabur Ltd, Ghaziabad, Uttar Pradesh, India) on its surface micromorphology.
Sixty discs (2mm thick and 10mm diameter) of nanocomposite material (Herculite Précis; KaVo Kerr, Brea, California, United States) were prepared using a silicon cylindrical mold. Initially, all the specimens were stored in artificial saliva in five Petri dishes; 12 specimens in each dish. In the Petri dishes, the specimens were immersed in the respective beverages once or twice a day. Before and after each immersion, the specimens were stored in artificial saliva at room temperature. Artificial saliva was changed each day, i.e., every 24 hours. The whole procedure was carried out for three months and then evaluated for color stability using a spectrophotometer and surface micromorphology using a scanning electron microscope. Now, the exposure of specimens to aerated drinks (Coca-Cola) and packaged orange juice (Real Orange) was put to a halt, and specimens were kept continuously in artificial saliva. This procedure was carried out for one month and then evaluated for color stability. The information was analyzed using PASW Statistics for Windows, Version 18.0 (Released 2009; SPSS Inc., Chicago, United States). A p-value of 0.05 was considered significant.
The p-value after three months, which is < 0.001 (p<0.05) indicates that the mean color difference values for groups I, II, III, IV, and V show a statistically significant change between the five groups, and similarly, the p-value after one month, which is < 0.001 (p<0.05) indicates that the mean color difference values for groups I, II, III, IV, and V show a statistically significant change between the five groups. Specimens immersed in the carbonated drink twice a day showed clinically more color change than packaged orange juice and artificial saliva on the composite restorative material. Coca-Cola, an aerated drink, was shown to have a higher erosive potential on the composite restorative material than Real Fruit Power Orange and fake saliva.
The findings are consistent with the hypothesis that repeated exposure to carbonated beverages (such as Coca-Cola and packaged juice) degrades the surface qualities of dental restorations.
本研究旨在评估一种纳米复合修复材料的颜色稳定性，以及碳酸软饮料（可口可乐；可口可乐公司，美国佐治亚州亚特兰大）和包装橙汁（真果力橙；达宝有限公司，印度北方邦加济阿巴德）对其表面微观形态的侵蚀潜力。
使用硅质圆柱形模具制备60个纳米复合材料（Herculite Précis；美国加利福尼亚州布雷亚的卡瓦科尔公司）圆盘（厚2mm，直径10mm）。最初，将所有标本储存在五个培养皿中的人工唾液中；每个培养皿中有12个标本。在培养皿中，标本每天浸入相应的饮料中一次或两次。每次浸入前后，标本在室温下储存在人工唾液中。每天更换人工唾液，即每24小时更换一次。整个过程持续三个月，然后使用分光光度计评估颜色稳定性，并使用扫描电子显微镜评估表面微观形态。现在，停止将标本暴露于充气饮料（可口可乐）和包装橙汁（真橙）中，并将标本持续保存在人工唾液中。这个过程持续一个月，然后评估颜色稳定性。使用Windows版PASW Statistics 18.0（2009年发布；美国芝加哥的SPSS公司）分析数据。p值小于0.05被认为具有统计学意义。
三个月后的p值<0.001（p<0.05），表明第一、二、三、四和五组的平均色差在五组之间有统计学显著变化，同样，一个月后的p值<0.001（p<0.05）表明第一、二、三、四和五组的平均色差在五组之间有统计学显著变化。每天浸入碳酸饮料两次的标本在复合修复材料上的临床颜色变化比包装橙汁和人工唾液更多。充气饮料可口可乐对复合修复材料的侵蚀潜力高于真果力橙和假唾液。
研究结果与反复接触碳酸饮料（如可口可乐和包装果汁）会降低牙齿修复体表面质量的假设一致。
