目的本横断面研究的目的是评估和比较居住在中部黑森（德国）农村地区或美因河畔法兰克福市（德国）的6-12岁学龄儿童中MIH的患病率。低矿化第二乳磨牙（HSPM）和MIH之间的可能关联进行了调查。此外，还将农村地区的MIH流行率数据与2002/2003学年在该地区进行的一项研究的数据进行了比较。方法在2014/2015学年，2103名儿童（6-12岁）在法律规定的年度校本牙科检查期间在中央黑森农村地区的9所学校（LDK）和美因河畔法兰克福市的5所学校（Ffm）进行了检查。八名先前校准的牙医工作的公共卫生保健机构评估的患病率HSPM/MIH（EAPD标准/严重程度规模的Wetzel和Reckel）和龋齿的经验（dmft/DMFT）。结果LDK组HSPM/MIH患病率为3.2%/9.4%，Ffm组为2.9%/17.4%。在大多数情况下，患有MIH的儿童有分界不清的混浊。在LDK中，低矿化的第一恒磨牙最常见的严重程度为2，而在Ffm中，严重程度为1占主导地位。患有HSPM的儿童也患有MIH的优势比为11.32（95%CI：6.73-19.03）。与2002/2003年LDK结果（MIH患病率为5.9%）相比，农村地区MIH患病率上升了3.5%。总的来说，受调查儿童的龋患率较低（DMFT 0.14-0.15）。在生活在德国不同地区的学龄儿童中可以诊断出具有区域差异的MIH（城乡比较）。HSPM的存在对MIH有预测价值。在农村地区，随着12年来矿化不足的第一恒磨牙数量的增加，需要进一步调查MIH的病因。
Aim The aim of the present cross-sectional study was to assess and compare the prevalence of MIH among 6-12-year-old school children living either in a rural area of Central Hesse (Germany) or in the city of Frankfurt on the Main (Germany). A possible association between hypomineralised second primary molars (HSPM) and MIH was investigated. Furthermore, the MIH prevalence data of the rural area were compared with those of a previous study conducted in this area in the school year 2002/2003. Methods In the school year 2014/2015, 2103 children (6-12 years of age) were examined during the annual school-based dental examinations prescribed by law at nine schools in the rural area of Central Hesse (LDK) and five schools in the city of Frankfurt on the Main (Ffm). Eight previously calibrated dentists working for the public healthcare authorities assessed the prevalence of HSPM/MIH (EAPD criteria/severity scale by Wetzel and Reckel) and the caries experience (dmft/DMFT). Results The prevalence of HSPM/MIH amounted 3.2%/9.4% in LDK and 2.9%/17.4% in Ffm. In the majority of cases, children with MIH had demarcated opacities. In LDK, hypomineralised first permanent molars were most commonly affected by severity degree 2, whereas in Ffm, severity degree 1 was predominant. Children suffering from HSPM had an odds ratio of 11.32 (95% CI: 6.73-19.03) for having MIH as well. Compared with the results of 2002/2003 in LDK (prevalence of MIH 5.9%), the MIH prevalence increased by 3.5% in the rural area. All in all, the caries experience among children under investigation was low (DMFT 0.14-0.15). Significance MIH may be diagnosed in school children living in different areas of Germany with regional variations (rural-urban comparison). The presence of HSPM is of predictive value for MIH. The increasing number of hypomineralised first permanent molars over 12 years of time in the rural area indicates a need for further investigation on the aetiology of MIH.
