The purpose of this study was to evaluate the effectiveness of several surface protectors for a glass-ionomer, a resin-modified glass-ionomer, and a polyacid-modified resin cement by determining dye uptake spectrophotometrically. 378 samples, made up of Ionofil U, Vitremer, and Dyract, were prepared and divided into groups of seven each. Positive and negative control specimens remained unprotected while the experimental specimens were protected with Finishing Gloss, Protect-It, LC Varnish, Adper Single Bond, or a nail varnish. The experimental groups and positive controls were immersed in 0.05% methylene blue solution, while the negative controls were immersed in deionized water. Results were evaluated using variance analysis. Of the Ionofil U group, Adper Single Bond exhibited the least effective surface coating among the materials tested, while the best surface protection was obtained with LC Varnish in the Dyract group. However, no statistically significant differences were observed in the Vitremer group.
本研究的目的是通过分光光度法测定染料摄取量，来评估几种表面保护剂对玻璃离子体、树脂改性玻璃离子体和聚酸改性树脂水门汀的有效性。制备了由Ionofil U、Vitremer和Dyract组成的378个样本，并将其分成每组7个样本的小组。阳性和阴性对照样本不做保护处理，而实验样本则分别用Finishing Gloss、Protect-It、LC清漆、Adper Single Bond或指甲油进行保护。将实验组和阳性对照样本浸入0.05%的亚甲蓝溶液中，而阴性对照样本则浸入去离子水中。使用方差分析对结果进行评估。在Ionofil U组中，在所测试的材料中Adper Single Bond表现出最无效的表面涂层，而在Dyract组中LC清漆提供了最佳的表面保护。然而，在Vitremer组中未观察到统计学上的显著差异。
