Based on the current state of the art regarding molar incisor hypomineralisation (MIH)-affected enamel, bonding systems are expected to play a relevant role on the restorative procedures when required. MIH-affected enamel is often subjected to posteruptive breakdown combined or not with carious lesions, predominantly on molars, and may also affect the aesthetics of anterior teeth. As unbalanced mineral and protein contents occur, understanding these alterations is essential before selecting the most appropriate adhesive systems, while bearing in mind their limitations. In particular, when dentin is involved due to enamel breakdown, the use of functional monomer-based bonding systems present in self-etching and universal systems produce a chemical interaction that enhance the bonding. So far, the overall recommendation relies on placing the margin of the restoration on clinically sound enamel, regardless of the category of the adhesive system.
基于当前摩尔牙本质发育不全（MIH）相关釉质的研究现状，在需要进行修复时，粘结系统有望在修复程序中发挥重要作用。MIH 相关的釉质经常会发生萌出后脱矿，并且可能会受到龋损的影响，主要发生在磨牙上，也可能会影响前牙的美观。由于矿物质和蛋白质含量失衡，在选择最合适的粘结系统之前，了解这些变化是至关重要的，同时要记住它们的局限性。特别是当由于釉质脱矿导致牙本质受累时，使用自酸蚀和通用系统中含有的功能性单体粘结系统会产生一种化学相互作用，从而增强粘结效果。到目前为止，总体建议是将修复体的边缘置于临床健康的釉质上，而不管粘结系统的类别如何。
