The objectives were to find out whether hypomineralized permanent first molars and incisors, known as Molar Incisor Hypomineralization (MIH), occurs all over Europe, whether its prevalence in each country is known and whether or not it is considered to be a clinical problem.
Clinical photos of MIH and a five-item questionnaire were sent to members of the European Academy of Paediatric Dentistry (EAPD). A total of 59 questionnaires were sent to members in 31 countries. After one month a reminder was sent to non-responders.
Fifty-four dentists (92%) in 30 countries (97%) returned the questionnaire. MIH was stated to occur in all but one country (the Czech Republic). Nearly all the responders (97%) stated that they were familiar with the clinical appearance of MIH and a majority saw it as a clinical problem. Furthermore, a large majority of the responders (90%) considered it important to map the prevalence of MIH in European countries as such data are available to only a limited extent.
Paediatric dentists in Europe are aware of MIH and the majority consider it to be a clinical problem. Only limited data are available on the prevalence of MIH. Comparable and representative prevalence studies are therefore urgently needed to gain more knowledge about the magnitude of MIH and related clinical problems.
本研究旨在确定低矿化恒第一磨牙和切牙（即磨牙切牙低矿化，MIH）是否在欧洲各地均有发生，每个国家的患病率是否已知，以及它是否被视为一个临床问题。
向欧洲儿童牙科学会（EAPD）成员发送了MIH的临床照片和一份包含五个项目的问卷。总共向31个国家的成员发送了59份问卷。一个月后，向未回复者发送了提醒。
30个国家（97%）的54名牙医（92%）返回了问卷。除一个国家（捷克共和国）外，其他所有国家均表示存在MIH。几乎所有回复者（97%）表示他们熟悉MIH的临床表现，并且大多数人将其视为一个临床问题。此外，绝大多数回复者（90%）认为绘制欧洲国家MIH的患病率很重要，因为此类数据目前非常有限。
欧洲的儿童牙医了解MIH，并且大多数人认为这是一个临床问题。目前关于MIH患病率的数据非常有限。因此，迫切需要开展具有可比性和代表性的患病率研究，以更深入地了解MIH的严重程度及相关临床问题。
