The application of the antioxidants after the teeth are bleached has been advocated to fasten the restorative process post-bleaching. The motive of this study was to examine and assess the micro-tensile binding strength of bleached enamel to the resin using a variety of antioxidant solutions. Finding the reason for the tooth fracture was the secondary outcome measured.
An study was planned with 100 human extracted teeth, with 20 in each group with one as controls and 4 others tested for the antioxidants sodium ascorbate, epigallocatechin gallate, chitosan, and proanthocyanidin application. The bond strength of bleached enamel to the resin was well as the failure type was assessed after the values were noted and compared using the ANOVA and Tukey's methods keeping < 0.05 as significant.
Epigallocatechin gallate specimens displayed the maximum micro-tensile bond strength under the investigational circumstances, whereas controls displayed the lowest micro-tensile bond strength. There was statistical alteration in micro-tensile bond strengths between all the groups except between epigallocatechin gallate vs chitosan and sodium ascorbate vs proanthocyanidin. High statistical significance was seen between the control and the antioxidant groups as well as between sodium ascorbate and epigallocatechin gallate and chitosan.
The antioxidant chemicals significantly augmented the bond strength of bleached enamel to the resin that had been bleached. Also, when compared to the other experimental groups, epigallocatechin gallate and chitosan treatment displayed the greatest mean bond strength values.
牙齿漂白后应用抗氧化剂被提倡用于加快漂白后的修复过程。本研究的目的是使用多种抗氧化剂溶液检测和评估漂白牙釉质与树脂之间的微拉伸结合强度。找出牙齿断裂的原因是测量的次要结果。
计划对100颗拔除的人类牙齿进行研究,每组20颗,一组作为对照,另外4组分别测试抗坏血酸钠、表没食子儿茶素没食子酸酯、壳聚糖和原花青素的应用情况。记录漂白牙釉质与树脂之间的粘结强度以及失效类型,然后使用方差分析和Tukey方法进行比较,将P<0.05视为具有显著性。
在研究条件下表没食子儿茶素没食子酸酯样本显示出最大的微拉伸粘结强度,而对照组显示出最低的微拉伸粘结强度。除表没食子儿茶素没食子酸酯与壳聚糖以及抗坏血酸钠与原花青素之间外,所有组之间的微拉伸粘结强度均有统计学差异。对照组与抗氧化剂组之间以及抗坏血酸钠与表没食子儿茶素没食子酸酯和壳聚糖之间存在高度统计学显著性。
抗氧化剂化学物质显著提高了漂白牙釉质与已漂白树脂之间的粘结强度。此外,与其他实验组相比,表没食子儿茶素没食子酸酯和壳聚糖处理显示出最大的平均粘结强度值。
