摘要:

目的 通过分析不同树脂材料对饮料色素的着色效果,比较渗透树脂与前牙美学树脂颜色稳定性的差异。方法 选择3种前牙美学树脂(Filtek Z250、Filtek Z350 XT、Beautiful Flow Plus F00)及人工早期龋渗透树脂(Icon)处理样本各20例,不同树脂样本分别分为2组(每组10例)分别置于咖啡溶液及蒸馏水中浸泡1、2、3周。应用Crystaleye分光光度比色仪进行样本颜色分析。结果 人工早期龋渗透树脂处理表面的着色明显高于其他前牙美学树脂(P<0.05)。所有实验树脂及渗透树脂处理表面的着色均随时间延长而增加,但第1周的着色最为显著,明显高于第2周及第3周的着色(P<0.05)。结论 人工早期龋渗透树脂处理表面较前牙美学树脂更易发生颜色改变。

Abstract:

Objective To investigate the color stability of infiltrant resin together with three other composites exposed to staining solution. Methods Three types of anterior aesthetic composite resins (Filtek Z250, Filtek Z350 XT, and Beautiful Flow Plus F00) and artificial caries with Icon infiltrant resin were used. The samples were randomly divided into two groups (each contained 10 specimens): coffee solution and distilled water immersion for three weeks. Color parameters were determined with the Crystaleye spectrophotometer. Results Artificial caries lesions infiltrated by Icon showed much higher ΔE than those infiltrated by other aesthetic resins (P<0.05). The discoloration of all the experimental resins and the artificial caries infiltrated with Icon increased with time, but the discoloration on the 1 st week was significantly higher than those on the 2 nd and 3 rd weeks. Conclusion Artificial caries infiltrated with Icon was more vulnerable and susceptive to food color than those infiltrated with other aesthetic composite resins.

Key words: infiltrant resin, composite resin, color stability
