Molar incisor hypomineralization (MIH) is a developmental dental defect and has a significant impact on the quality of life of affected individuals. Most of the prevalence studies of MIH have been carried out in the European countries; very little data are available from India.
The aim and objective of this study was to determine the prevalence of MIH in 8-15-year-old Malayalee school children in and around Muvattupuzha, Kerala.
A cross-sectional epidemiological study was conducted in 5318 healthy Malayalee school children aged between 8 and 15 years in and around Muvattupuzha.
The first permanent molars (FPMs) and all permanent incisors were examined for MIH using the European Academy of Paediatric Dentistry 2003 diagnostic criteria. The severity of hypomineralization was recorded according to the Wetzel and Reckel scale.
The data were analyzed using the Statistical Package for the Social Sciences software version 20.0, and a comparison between groups was carried out using the Chi-square test. P ≤ 0.05 was considered for statistical significance.
A total of 216 children were diagnosed with MIH. The maximum MIH-affected tooth was found to be mandibular right FPM (186), followed by mandibular left FPM (172), maxillary left FPM (160), and maxillary right FPM (156).
The prevalence of MIH in permanent dentition of Malayalee school children in and around Muvattupuzha was 4.1%. Among the MIH-affected children, very few have undertaken dental treatment for the same. Hence, proper awareness and planned preventive and restorative programs are required to minimize the problem.
磨牙切牙矿化不全（MIH）是一种发育性牙体缺损，对受影响个体的生活质量有重大影响。大多数关于MIH的患病率研究是在欧洲国家开展的；来自印度的数据非常少。
本研究的目的是确定喀拉拉邦穆瓦图普扎及其周边地区8至15岁马拉雅拉姆族学童中MIH的患病率。
对穆瓦图普扎及其周边地区5318名年龄在8至15岁的健康马拉雅拉姆族学童进行了一项横断面流行病学研究。
根据欧洲儿童牙科学会2003年诊断标准，对第一恒磨牙（FPMs）和所有恒切牙进行MIH检查。根据韦策尔和雷克尔量表记录矿化不全的严重程度。
使用社会科学统计软件包20.0版对数据进行分析，并使用卡方检验进行组间比较。P≤0.05被认为具有统计学意义。
共有216名儿童被诊断为MIH。发现受MIH影响最多的牙齿是下颌右FPM（186颗），其次是下颌左FPM（172颗）、上颌左FPM（160颗）和上颌右FPM（156颗）。
穆瓦图普扎及其周边地区马拉雅拉姆族学童恒牙列中MIH的患病率为4.1%。在受MIH影响的儿童中，很少有人为此接受过牙科治疗。因此，需要提高适当的认识并制定有计划的预防和修复方案，以尽量减少该问题。
