Abstract

Background: This study compared the color stability of resin-modified glass ionomer (RMGI) and Cention N bioactive restorative material following exposure to different coloring solutions.

Materials and methods: In this in vitro experimental study, 12 specimens were fabricated from Cention N and Fuji II LC RMGI and immersed in Turkish coffee, Nescafe, cola, and distilled water as control (n = 3). The color parameters of the specimens were measured after 1, 7, and 28 days of immersion in the respective solutions, and their color change (ΔE) was calculated. Data were analyzed using repeated measures ANOVA Friedman test and two-way ANOVA (alpha = 0.05).

Results: On day 1, the highest and lowest ΔE values were noted in Cention N specimens immersed in Nescafe and Cention N specimens immersed in cola, respectively. On days 7 and 28, the highest and lowest ΔE values were found in RMGI specimens immersed in Nescafe and Cention N specimens immersed in cola, respectively. The effects of the type of material and type of coloring solution and their interaction effect on ΔE of specimens at different time points were statistically significant (P < 0.05).

Conclusion: Within the limitations of this in vitro study, the results showed that Fuji II LC RMGI had lower color stability than Cention N in the long term. Nescafe caused the greatest discoloration in Fuji II LC, while Turkish coffee caused the greatest discoloration in Cention N specimens.

树脂改性玻璃离聚体与生物活性修复材料颜色稳定性的体外比较。

背景：本研究比较了树脂改性玻璃离聚体（RMGI）和Cention N生物活性修复材料在不同着色剂作用下的颜色稳定性。材料与方法：体外实验研究采用Cention N和Fuji II LC RMGI制备12个标本，分别浸泡土耳其咖啡、雀巢咖啡、可乐和蒸馏水作为对照（N = 3）。分别在不同的溶液中浸泡1、7、28天后，测量试样的颜色参数，并计算其颜色变化（ΔE）。数据分析采用重复测量方差分析Friedman检验和双向方差分析（α = 0.05）。结果：第1天，浸泡在雀巢咖啡中的Cention N和浸泡在可乐中的Cention N分别达到最高和最低ΔE值。第7天和第28天，雀巢咖啡浸泡的RMGI和可乐浸泡的Cention N分别达到最高和最低ΔE值。不同时间点材料类型和着色液类型及其交互作用对ΔE的影响均有统计学意义（P < 0.05）。结论：在体外研究的限制下，富士II LC RMGI的长期颜色稳定性低于健宁N。雀巢咖啡在富士II LC中引起最大的变色，而土耳其咖啡在Cention N样品中引起最大的变色。
