背景：采用渗透树脂微创技术治疗釉质脱矿的修复效果优于传统的再矿化治疗，但目前研究渗透树脂修复非实质性缺损龋病后颜色变化的文献很少。 　　目的：通过体外研究评估渗透树脂修复早期釉质龋的颜色稳定性。 　　方法：将具有完整釉质面的48颗人离体牙浸泡在脱矿液中4周，制作成人工龋模型，之后进行渗透树脂修复，再随机均分成4组，分别置于红酒、咖啡、茶和人工唾液中浸泡2，4周。采用分光光度仪对病损区的颜色进行检测，以渗透树脂治疗后的检测作为基准色，计算出色差数值。 　　结果与结论：浸泡后，4组样本都有不同程度的颜色变化。浸泡2周后，颜色变化大小顺序为：红酒>咖啡>茶>人工唾液，4组间比较差异有显著性意义(P<0.05)；浸泡4周后，颜色变化大小顺序为：红酒≈咖啡>茶>人工唾液，红酒组与咖啡组比较差异无显著性意义(P >0.05)，其他组间比较差异有显著性意义(P<0.05)。红酒组与咖啡组浸泡不同时间点的颜色变化比较差异有显著性意义(P<0.05)。浸泡在红酒、咖啡和茶一定的时间后，均显示在临床上不可以接受的色彩改变(?E >3.7)。说明渗透树脂颜色的稳定性受浸泡时间长短和浸泡溶液种类的影响，其中红酒、咖啡对其颜色稳定性影响较大，在人工唾液中颜色稳定性最好。

BACKGROUND:The resin infiltration technique for masking white spot lesions has obtained a result superior to the conventional remineralization. Up to now, few studies have evaluated the color of carious incipient lesions treated with the resin infiltration. OBJECTIVE:To assess the color change of caries incipient lesions in the enamel treated with resin infiltration. METHODS: Forty-eight extracted teeth were exposed to demineralizing solution for 4 weeks to establish artificial caries models. Then artificial caries models were treated with resin infiltration and randomized into four groups: these specimens were immersed in red wine, coffee, tea and artificial saliva for 2 and 4 weeks, respectively. The base line color was evaluated by spectrophotometer. The variation in color (ΔE) was analyzed by one-way analysis of variance and Tukey’s tests. RESULTS AND CONCLUSION:Al specimens underwent color and lightness changes, irrespective of immersion media. After 2 weeks of immersion, ΔE values were ranked as folows: red wine > coffee > tea > artificial saliva, and there were significant differences between four groups (P < 0.05). After 4 weeks of immersion,ΔE values were ranked as folows: red wine≈ coffee > tea > artificial saliva, and there were significant differences between four groups (P < 0.05) but not between the red wine and coffee groups (P > 0.05). Significant changes in the color were found in the red wine and coffee groups at different time after immersion (P < 0.05). Immersed in red wine, coffee and tea, the?E value was > 3.7, which is not acceptable in clinic. These findings indicate that the color stability of carious incipient lesions located in the enamel treated with resin infiltration is associated with the soak solution and soak time. In addition, immersion in red wine and coffee results in significantly increased color alteration (ΔE) compared with the artificial saliva.
