Abstract

Introduction: Molar Incisor Hypomineralisation (MIH) is an enamel defect with white, yellow or black colour due to minerals insufficient during tooth development. The abnormality of prismatic enamel structures and tooth hypersensitivity on patients with MIH may disturb the success rate of restoration. The objective of this research was to determine the prevalence of MIH in primary school children. Methods: A cross-sectional study with purposive sampling on 619 primary school children at Pasteur Urban Village of Bandung City, Indonesia. All dentition were scored using the European Association of Paediatric Dentist (EAPD) MIH scoring sheet, and oral hygiene status assessment with simplified OHI. All data were descriptively described using distribution table. Results: Distribution of MIH on total of 619 children were scored as follows: 0,1,1a, 2, 2a, 3, 4, 5, 6, 7, 8, 9,10 (0 = free enamel defect; 6, 7, and 8 = alteration to non MIH; 1 -5 and 9 -10 = MIH) with frequencies 417(67.36%), 39(6.30%), 60(.65%), 13(2.10%), 0(0.00%), 7(1.13%), 0(0.00%), 4(0.65%), 0(0.00%), 26(4.20%), 58(9.36%), 0(0.00%), and 49(7.91%) respectively. Conclusion: Prevalence of children with MIH in primary school is quite high (19% (118 out of 619 participants)). The highest prevalence is found at the 11 years old group with 49 participants (36.84%), while the prevalence in boys (83 (62.4%)) is found to be higher than girls (50 (37.59%)).Keywords: Prevalence, Molar Incisor Hypomineralisation (MIH), primary school children

小学儿童磨牙切口低矿化（MIH）的患病率

简介：臼齿切迹低矿化（MIH）是一种釉质缺陷，颜色为白色、黄色或黑色，原因是牙齿发育过程中矿物质不足。MIH患者的棱柱状釉质结构异常和牙齿过敏可能会干扰修复的成功率。本研究的目的是确定小学儿童MIH的患病率。方法：对印度尼西亚万隆市巴斯德城中村619名小学生进行有针对性的横断面调查。使用欧洲儿科牙医协会（EAPD）MIH评分表对所有牙列进行评分，并使用简化的OHI对口腔卫生状况进行评估。使用分布表对所有数据进行了描述性描述。结果：619名儿童的MIH分布情况如下：0,1,1a，2，2a，3，4，5，6，7，8，9,10（0=游离釉质缺损；6，7和8=非MIH改变；1-5和9-10=MIH），频率为417（67.36%），39（6.30%），60（.65%），13（2.10%），0（0.00%），7（1.13%），0分别为49例（7.91%）。结论：小学MIH儿童的患病率相当高（19%（619名参与者中有118人）。患病率最高的是11岁组，共有49名参与者（36.84%），而男孩（83名（62.4%））的患病率高于女孩（50名（37.59%））
