摘要
目的 探讨三种不同处理方法对釉质脱矿色泽稳定性的影响.方法 将60例釉面完整的人前磨牙随机分为ICON渗透树脂组、ICON 0.1％氟化钠组、ICON渗透树脂组联合生物活性玻璃组,每组分为4组,分别用红酒、咖啡、茶和人工唾液浸泡,在24h,1w,2w,4w时采用分光光度仪测量,分析计算出各牙的△E值.结果 不同时间、溶液、修复方式对治疗早期釉质脱矿后牙面颜色稳定性存在明显差异.在四个时间点,△E:红酒＞咖啡＞茶＞人工唾液,4组间比较差异有统计学意义(P＜0.05);一定时间后,浸泡在红酒和咖啡的△E均大于3.7,表明色彩改变在临床上不可接受.治疗后牙面颜色稳定性:ICON渗透性树脂联合生物活性玻璃治疗组＞ICON渗透性树脂联合0.1％的氟化钠治疗组＞ICON渗透性树脂组,差异有统计学意义(P＜0.05).结论 ICON渗透性树脂联合生物活性玻璃治疗早期釉质脱矿后颜色维持的稳定性更好,临床操作方法简便快捷且安全性高,后期美学效果更稳定持久.
Abstract
Objective To explore the influence of resin infiltration technique combined with the application of bioactive glass on the color stability of tooth surface of early enamel caries.Methods A total of 60 human premolars with an intact enamel were randomly divided into the Icon resin infiltration(ICON)group,ICON+0.1％NaCl group and ICON+bioactive glass group.In each group,premolars were subdivided into 4 groups and immersed in red wine,coffee,tea and artificial saliva.At 24 h,1 week,2 weeks and 4 weeks,color changes in premolars were assessed by calculating the ΔE value using a spectrophotometer.Results There were significant differences in the color stability of tooth surfaces of early enamel caries by different treatment approaches,immersed in different solutions and at different time points(P＜0.05).There was a significant difference in the ΔE value of premolars immersed in the four solutions,which was significantly greater in those immersed in the red wine,followed by the coffee,tea and artificial saliva(P＜0.05).The ΔE value of premolars immersed in the red wine and coffee at the four time points was greater than 3.7,indicating an unacceptable color change.There was a significant difference in the color stability after the treatment,which was significantly higher in ICON+bioactive glass group,followed by ICON+0.1％NaCl group and ICON group(P＜0.05).Conclusion Icon resin infiltration combined with bioactive glass provides a better color stability for the treatment of early enamel caries,which is featured by simple procedures,high safety and stable and long-lasting aesthetic outcome.
