The Mercox-Rhodamin Method for marginal microleakage test is a kind of dye penetration method. The specimens were immersed in the mixture of Mercox which is a low viscosity resin and used for vascular architecture, and Rhodamin B which is a fluoresent dye, by applying a pressure of 5 Kg/cm^2 using a compressed air for 15 minutes. When microleakage is tested by using a dye penetration, the specimens must be sectionded, only the leakage in the sectioned plane can be observed and this leakage is not the sequence one. On the other hand, in the Mercox-Rhodamin method, When the specimens are immersed in the 10% Nitric acid, Enamel and Dentin disolve. It allows direct observation of the entire area of the penetrated Mercpx-Rhodamin resin.Other advantages of using the Mercox-Rhodamin Method are as follows :1. The examination of microleakage using this method tends to evaluate the higher degree of microleakage than that using the dye method.2. This method was an effective microleakage test which demonstrates clear differences in microleakage of composite resin restorations.3. In this leakage test, the area and passway of microleakage is directly observed. The leakage can be evaluated by TV immage processor (TVIP4100II), making statistical analysis easier.4. This leakage test is a superior test method to directly find the comprex passway of leakage in 3D.

Mercox-Rhodamin法是一种染料渗透法。通过使用压缩空气施加5 Kg/cm ^2的压力15分钟，将样本浸入Mercox和Rhodamin B的混合物中，Mercox是一种低粘度树脂，用于血管结构，Rhodamin B是一种荧光染料。用染料渗透法测试微渗漏时，必须将试件切片，只能观察到切片内的渗漏，而不是顺序渗漏。而Mercox-Rhodamin法中，当试样浸泡在10%硝酸中时，牙釉质和牙本质溶解。它允许直接观察渗透Mercpx-罗丹明树脂的整个区域。使用Mercox-罗丹明方法的其他优点如下：1.与染色法相比，该方法检测微渗漏的程度更高.该方法是一种有效的微渗漏测试方法，复合树脂充填体的微渗漏差异明显.在该泄漏测试中，直接观察微泄漏的面积和通道。采用TVIP 4100 II电视图像处理器对泄漏情况进行评价，并进行统计分析.该泄漏测试是一种上级测试方法，可直接在3D中找到泄漏的通道。
