The primary intent of this scientific research is to effectively assess and collate the inherent potentiality of the two selected investigative composite materials in effectual maintenance of their standard color following subsequent and consistent submersion in customary available pediatric liquids consumed by children. The above investigation will be effectively estimated using the Commission Internationale de I'Eclairege (CIE) Lab* system-based spectrophotometer.
A total of 100 composites of spheroidal plates were fabricated accordingly. A total of 50 nanohybrids and microhybrids of 8 × 2 mm were fabricated and timely cured using a light cure unit for an approximated time period of 40 seconds. This was then trialled by subsequent sample submersion in the specified five immersive media, which include mineral water, tea, Mirinda, pomegranate juice, and iron syrup, respectively, for a definitive and habitual time of thrice daily up to 15 minutes for a duration of 28 experimental days. The respective marked readings were recorded on the 7th, 14th, 21st, and 28th days by utilization of a CIE Lab* system-based spectrophotometer.
Mann-Whitney test and Friedman's Test were utilized for statistical evaluation of the above-described experimental research. The -value was statistically found to be significant at ( < 0.001).
The conclusive findings from the above-defined experimental research were that iron syrup was found to cause the most noticeable and definitive staining in comparison to other immersive media. Nanohybrid composite restorative material was hence identified as being highly resistant to staining and possessing an undeniable ability to maintain the persistent color, unlike its microhybrid counterpart.
The esthetic appearance is an important factor for both the parents and children; hence, this determines that the longevity of color stability of restorative materials is of valid significance.

本科学研究的主要目的是有效评估和整理两种选定的研究性复合材料在随后持续浸泡于儿童常用的儿科液体中后，维持其标准颜色的内在潜力。上述研究将使用基于国际照明委员会（CIE）Lab*系统的分光光度计进行有效评估。
据此制作了总共100个球状板复合材料。制作了总共50个8×2毫米的纳米混合材料和微混合材料，并及时使用光固化装置固化约40秒。然后将其随后分别浸泡在指定的五种浸泡介质中进行试验，这五种介质分别为矿泉水、茶、美年达、石榴汁和铁糖浆，每天浸泡三次，每次浸泡15分钟，持续28个实验日。在第7天、第14天、第21天和第28天，使用基于CIE Lab*系统的分光光度计记录各自的标记读数。
使用曼-惠特尼检验和弗里德曼检验对上述实验研究进行统计评估。统计学上发现p值在（p<0.001）时具有显著性。
上述定义的实验研究的最终结果是，与其他浸泡介质相比，发现铁糖浆会导致最明显和确定的染色。因此，纳米混合复合修复材料被确定为具有高度抗染色性，并且与微混合材料不同，具有不可否认的保持持久颜色的能力。
美观外观对父母和孩子来说都是一个重要因素；因此，这决定了修复材料颜色稳定性的持久性具有重要意义。
