Esthetic orthodontic wires are preferred for their ease to fit in with natural tooth color, but their susceptibility to staining in the oral environment poses a concern. Various Coatings such as Teflon and Epoxy aim to enhance appearance and biocompatibility but may still result in discoloration. Understanding the color stability of these wires under different staining conditions is crucial for a better and enhanced treatment plan.
This study intended to assess the color stability of esthetic orthodontic wires under various staining solutions that are often used in daily life.
Color changes of Teflon and Epoxy-coated esthetic orthodontic wires were meticulously measured at baseline, 7, 14, and 21-day intervals utilizing the precise CIE Lab* color measurement system. A total of thirty-two samples of wires from each brand were prepared (n= 8/group) and immersed in staining solutions (coffee, tea, cola, and saffron). The color change within and between the groups was statistically evaluated (p< 0.05).
Significant variations in color stability were observed across different staining solutions. Saffron emerged as the most potent agent, inducing the most pronounced color changes, whereas cola demonstrated the least impact. Furthermore, Epoxy-coated wires consistently exhibited superior color stability compared to their Teflon-coated counterparts across all staining solutions and time intervals.
This study underlines the significance for orthodontists to consider staining agents' possible effects on orthodontic wires into account when selecting the orthodontic wires. The findings suggest that Epoxy-coated wires hold promise in mitigating discoloration issues during orthodontic therapy.
美观的正畸钢丝因其易于与天然牙齿颜色相匹配而备受青睐，但它们在口腔环境中易被染色的问题令人担忧。诸如特氟龙和环氧树脂等各种涂层旨在改善外观和生物相容性，但仍可能导致变色。了解这些钢丝在不同染色条件下的颜色稳定性对于制定更好、更完善的治疗方案至关重要。
本研究旨在评估美观正畸钢丝在日常生活中常用的各种染色溶液中的颜色稳定性。
使用精确的CIE Lab*颜色测量系统，在基线、间隔7天、14天和21天时，精心测量特氟龙和环氧树脂涂层的美观正畸钢丝的颜色变化。每个品牌共制备了32根钢丝样本（n = 8/组），并将其浸入染色溶液（咖啡、茶、可乐和藏红花）中。对组内和组间的颜色变化进行统计学评估（p < 0.05）。
在不同的染色溶液中观察到颜色稳定性存在显著差异。藏红花是最有效的染色剂，引起的颜色变化最为明显，而可乐的影响最小。此外，在所有染色溶液和时间间隔内，环氧树脂涂层的钢丝始终比特氟龙涂层的钢丝表现出更好的颜色稳定性。
本研究强调了正畸医生在选择正畸钢丝时考虑染色剂对正畸钢丝可能产生的影响的重要性。研究结果表明，环氧树脂涂层的钢丝有望减轻正畸治疗期间的变色问题。
