Is to evaluate the color stability of rhodium-coated aesthetic archwires after immersion in two types of mouthwashes (fluoridated and nonfluoridated), study the effect of immersion time, and to compare the effect of these solutions on color stability of the aesthetic archwires.
35 rhodium-coated aesthetic archwires were prepared and divided two halves, arranged in seven strips (each strip contains 10 wires) and immersed in Deionized water, Sidrazac and Biofresh solution. The measurements of the color have been carried out through a computed spectrophotometer based on Commission Internationale de I'Eclairage system, and color variations (Δ ), color measurements were repeated 7 and 21 days after immersion in the solution. Statistical analyses include mean, standard deviation, minimum, maximum, and inferential statistics which include ANOVA and Tukey (HSD) for testing for any statistically significant differences in light reflection of the groups; -test was used to test for differences in immersion time intervals. The significance level has been set at ≤ 0.05.
Both types of mouthwashes resulted in color changes in different degrees and a higher color instability amount has been noted with Sidrazac-fluoridated mouthwashes, The color change amount has been increased with the time being statistically higher in 3 weeks of immersion, while there is nonsignificant color change after immersion in the Biofresh mouthwash.
Rhodium-coated archwire shows high color changes in Sidrazac-fluoridated mouthwashes and nonsignificant color change after immersion in the Biofresh mouthwash.
评估镀铑美观弓丝在两种漱口水（含氟和不含氟）中浸泡后的颜色稳定性，研究浸泡时间的影响，并比较这些溶液对美观弓丝颜色稳定性的影响。
制备35根镀铑美观弓丝并分成两半，排列成七条（每条包含10根弓丝），并浸泡在去离子水、西地碘溶液和Biofresh溶液中。通过基于国际照明委员会系统的计算机分光光度计进行颜色测量，在溶液中浸泡7天和21天后重复颜色测量。统计分析包括均值、标准差、最小值、最大值以及推断统计，其中包括方差分析和用于检验各组光反射是否存在任何统计学显著差异的Tukey（HSD）检验；t检验用于检验浸泡时间间隔的差异。显著性水平设定为≤0.05。
两种漱口水均导致不同程度的颜色变化，西地碘含氟漱口水的颜色不稳定性更高，颜色变化量随时间增加，浸泡3周时在统计学上更高，而浸泡在Biofresh漱口水后颜色变化不显著。
镀铑弓丝在西地碘含氟漱口中显示出高颜色变化，而浸泡在Biofresh漱口水后颜色变化不显著。
