Molar incisor hypomineralization (MIH) is one of the most pressing issues in paediatric dentistry. It is a qualitative enamel defect of systemic origin that affects at least one first permanent molar and can also be associated with permanent incisors. However, the same defects have also been observed on primary molars and other permanent teeth. Hypomineralised enamel has less distinct prisms edges and crystals and the interprismatic space is more marked. Children with MIH undergo dental treatment nearly 10 times more than unaffected children. Preventive treatment following the diagnosis of MIH should take into account patient's age and collaboration, patient's caries risk, type and extension of demarcated lesions and hypersensitivity. Risk assessment and early diagnosis are key factors to an effective and conservative treatment.
磨牙牙釉质发育不全（MIH）是儿童牙科领域最紧迫的问题之一。它是一种系统性起源的釉质质量缺陷，至少影响一颗第一恒磨牙，也可能与恒切牙有关。然而，同样的缺陷也在乳磨牙和其他恒牙上观察到。矿化不足的釉质棱柱边缘和晶体不太明显，晶间空间更明显。患有 MIH 的儿童接受牙科治疗的次数几乎是未受影响儿童的 10 倍。在 MIH 诊断后，应根据患者的年龄和合作情况、龋齿风险、界限分明的病变类型和范围以及过敏情况来考虑预防性治疗。风险评估和早期诊断是有效和保守治疗的关键因素。
