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.

麦考克斯-罗丹明法边缘微渗漏试验是染料渗透法的一种。将标本浸泡在用于血管结构的低粘度树脂Mercox和荧光染料罗丹明B的混合物中，压力为5 kg/cm2，压缩空气中浸泡15分钟。当用染料渗透法测试微渗漏时，必须对试件进行切片，只能观察到剖面处的渗漏，这次渗漏不是顺序渗漏。另一方面，在Mercox-RoDamin法中，当标本浸泡在10%的硝酸、牙釉质和牙本质溶液中时。该方法还具有以下优点：1.用该方法检测微渗漏倾向于评价比染料法更高的微渗漏程度。该方法是一种有效的微渗漏试验，表明复合树脂修复体的微渗漏有明显的差异。在这次渗漏试验中，可以直接观察到微渗漏的面积和通道。泄漏情况可通过电视图像处理器(TVIP4100II)进行评估，便于统计分析。该渗漏试验是直接在三维空间中发现渗漏通道的一种较好的试验方法。
