This article aims to describe a new technique for predicting the results of resin infiltration procedure in molar incisor hypomineralization lesions, named Infiltration Monitoring by Transillumination. The technique involves the use of transillumination together with ethanol application during the steps of lesion body opening and resin penetration. It provides color contrast that enhances the removal of the less porous surface layer and controls the effectiveness of resin infiltration within the lesion.
The clinical procedure presented illustrates the steps involved in the resin infiltration procedure for color masking of molar incisor hypomineralization lesions in anterior teeth, highlighting the use of transillumination both for monitoring the lesion body opening step and the resin infiltration process.
The monitoring with transillumination during the ethanol test can assist the removal of the enamel external layer over the lesion, necessary to expose the inner porosity to be infiltrated, in a very precise and conservative way. In addition, it can effectively help to determine the moment when the infiltrant resin has fully penetrated the lesion.
The Infiltration Monitoring by Transillumination technique offers the possibility to precisely control the infiltration procedure in molar incisor hypomineralization lesions, thereby improving the predictability of the esthetic outcome.
本文旨在描述一种预测磨牙切牙矿化不全病变树脂渗透治疗效果的新技术，即透照渗透监测技术。该技术在病变体打开和树脂渗透步骤中，将透照与乙醇应用相结合。它提供颜色对比，增强了较致密表面层的去除效果，并控制了病变内树脂渗透的有效性。
所介绍的临床操作展示了前牙磨牙切牙矿化不全病变颜色遮盖树脂渗透治疗的步骤，突出了在监测病变体打开步骤和树脂渗透过程中使用透照的情况。
乙醇测试期间的透照监测能够以非常精确和保守的方式，协助去除病变上方的釉质外层，这对于暴露待渗透的内部孔隙是必要的。此外，它可以有效地帮助确定渗透树脂完全渗透病变的时刻。
透照渗透监测技术为精确控制磨牙切牙矿化不全病变的渗透治疗提供了可能，从而提高了美学效果的可预测性。
