Stained enamel opacities are frequently encountered in dental practice. However, due to the risk of unaesthetic outcome, managing such lesions by resin infiltration techniques alone is not advised. Therefore, performing external bleaching before resin infiltration procedure is mandatory to eliminate stains from the hypomineralized lesions in order to aesthetically infiltrate them. In this work, we describe clinical cases in which external bleaching and resin infiltration techniques were used for managing stained enamel hypomineralized lesions related to traumatic dental injuries and molar incisor hypomineralization. Despite the fact that this approach has some limitations, it could be concluded that external bleaching associated with the resin infiltration technique shows promising results to aesthetically manage stained enamel opacities when the stain is totally removed after bleaching.
在牙科实践中经常会遇到染色的牙釉质不透明区。然而，由于存在美观效果不佳的风险，不建议仅通过树脂渗透技术来处理此类病变。因此，在树脂渗透程序之前进行外部漂白以消除低矿化病变中的污渍，从而在美观上对其进行渗透是必不可少的。在这项工作中，我们描述了一些临床病例，其中外部漂白和树脂渗透技术被用于处理与牙外伤和磨牙切牙低矿化相关的染色牙釉质低矿化病变。尽管这种方法有一些局限性，但可以得出结论，当漂白后污渍被完全去除时，与树脂渗透技术相结合的外部漂白在美观处理染色牙釉质不透明区方面显示出有前景的结果。
