Abstract

Purpose: To evaluate tooth discoloration after the use of calcium silicate-based materials and to examine the effect of internal bleaching on tooth discoloration.

Materials and methods: The specimens were randomly divided into two experimental groups (n = 45) and a control group (n = 6). Cavities were filled with ProRoot MTA (Dentsply) in Group 1 and Biodentine (Septodont) in Group 2. Color measurements were taken with a spectrophotometer before and after the application of materials at 1 week and then at 13, and 6 months. After 6 months, Groups 1 and 2 were divided into three subgroups according to internal bleaching techniques. All color change ratios and lightness differences were calculated using the CIE L*a*b* system. Data were analyzed using repeated ANOVA and the Kruskal-Wallis test (P = .05).

Results: There were statistically significant differences between Groups 1 and 2 at all time intervals (P < .05). Group 1 showed more discoloration than Group 2 (P < .05). There were no significant differences between the bleaching agents (P > .05). Additionally, specimens in both groups became lighter than their initial color (P < .05).

Conclusion: Teeth treated with ProRoot MTA exhibited darkening at 1 week that increased over time, whereas those treated with Biodentine maintained the lightness for 6 months.

硅酸钙基材料对牙齿变色的影响及漂白后颜色变化的评估：分光光度法研究。

目的：评估使用硅酸钙基材料后的牙齿变色，并检查内部漂白对牙齿变色的影响。材料和方法：将标本随机分为两个实验组（n=45）和一个对照组（n=6）。第1组用ProRoot MTA（Dentsply）填充空腔，第2组用Biodentine（Septodon）填充空腔。在施用材料之前和之后的1周，然后在13个月和6个月，用分光光度计进行颜色测量。6个月后，第1组和第2组根据内部漂白技术分为三个亚组。使用CIE L*a*b*系统计算所有颜色变化率和亮度差异。使用重复方差分析和Kruskal-Wallis检验对数据进行分析（P=.05）。结果：第1组和第2组在所有时间间隔都有统计学上的显著差异（P<.05）。第1组比第2组变色更多（P<0.05）。漂白剂之间没有显着差异（P>.05）。此外，两组标本的颜色都比最初的颜色浅（P＜0.05）。结论：ProRoot MTA治疗的牙齿在1周时表现出变暗，并随着时间的推移而增加，而Biodentine治疗的牙齿则保持了6个月的亮度。
