Molar incisor hypomineralization (MIH) is a developmental disturbance concerning permanent incisors and first permanent molars. The aim of this study was to ascertain the frequency of MIH in the region of central Hesse, Germany.
1,022 children aged 6 to 12 years were surveyed during routine school-based dental examinations, which were conducted by the regional public health department. Symptoms of MIH were recorded and a DMF-T evaluation was carried out.
Approximately 6 percent (5.9 percent) of all examined children showed at least one ill-structured first permanent molar in terms of MIH. Furthermore, 57.9 percent of these children with hypomineralized first molars also showed changes in the enamel structure of the permanent incisors. Altogether, children with MIH showed a significantly higher DMF-T value for permanent teeth than children without MIH.
A carefully managed recall program for children affected by MIH is essential with regard to the increasing importance of preventive and restorative measures.
磨牙症伴切牙矿化不全（MIH）是一种涉及恒牙切牙和第一恒磨牙的发育障碍。本研究的目的是确定德国黑森州中部地区MIH的发生率。
在地区公共卫生部门进行的常规学校牙科检查中，对1022名6至12岁的儿童进行了调查。记录MIH的症状并进行DMF-T评估。
在所有接受检查的儿童中，约6%（5.9%）的儿童至少有一颗第一恒磨牙存在矿化不全的结构异常。此外，这些第一磨牙矿化不全的儿童中，57.9%的儿童恒牙切牙的釉质结构也有变化。总体而言，患有MIH的儿童恒牙的DMF-T值明显高于未患MIH的儿童。
鉴于预防和修复措施的重要性日益增加，为受MIH影响的儿童精心管理召回计划至关重要。
