本研究的目的是评估树脂涂层作为防止使用不同水泥植入的全铸冠下方边缘渗漏的方法的有效性。对 64 颗拔除的前磨牙进行了标准全铸冠预备。然后将这些样品分为四组，每组一半在制备后涂有牙本质涂层材料。使用锌水泥、Fuji I、Vitremer 或 C&B Metabond 将牙冠固定在牙齿上。样品进行了 10,000 次热循环。然后将它们浸入赤藓红溶液中，切片并在显微镜下观察。使用 0-4 点系统进行微泄漏分析。对数据进行统计分析。使用 Fuji I 和 Vitremer，涂层样品和未涂层样品之间存在显着差异。结果表明，与这两种水泥一起使用时，树脂涂层可以减少边缘渗漏量。
The purpose of this study was to evaluate the effectiveness of resin coating as a means of preventing marginal leakage beneath full cast crowns which were emplaced using different cements. Standard full cast crown preparation was made on 64 extracted premolars. These samples were then divided into four groups, with half of each group coated with dentin coating material after preparation. Crowns were cemented onto the teeth using zinc cement, Fuji I, Vitremer, or C&B Metabond. The samples were thermal-cycled for 10,000 cycles. They were then immersed in erythrosine solution, sectioned, and observed under a microscope. Microleakage analyses were performed using a 0-4 point system. The data were statistically analyzed. There were significant differences between the coated specimens and the uncoated specimens using Fuji I and Vitremer. The results showed that a resin coating could decrease the amount of marginal leakage when applied with these two cements.
