No data is available on hypomineralization in the full complement of primary dentition.
To report on the prevalence and clinical presentation of enamel hypomineralization (EH) in the primary dentition.
A cross-sectional observational study with a random sample of 948, 4-6-year-old schoolchildren of Gautam Buddh Nagar, Uttar Pradesh, India, was conducted after approval from the Institutional Ethics Committee. European Academy of Paediatric Dentistry (EAPD) (2003) criteria were employed to score EH in all primary teeth. A single experienced examiner conducted an entire clinical examination of the study population. Data were expressed as the prevalence, type, extent, and distribution. Further analyses were conducted to compare the prevalence and distribution of different types of lesions in affected subjects using student -tests and analysis of variance (ANOVA).
An overall prevalence of 7.51% (71/948) was reported. A total of 2.75 ± 1.735 teeth/subject were reported to be affected. The most common lesion was creamy white opacity ( = 0.002), while posteruptive breakdown (PEB) was observed in 40.85% (29/71) of affected subjects.
The prevalence of EH in primary dentition was 7.51%. Further studies mapping the prevalence as well as possible links with molar incisor hypomineralization (MIH) in other geographical locations of the world are required.

关于乳牙列全部牙齿矿化不足的数据尚无可用资料。
报告乳牙列中釉质矿化不足（EH）的患病率及临床表现。
经机构伦理委员会批准，对印度北方邦古塔姆·布德哈·纳加尔的948名4至6岁学童进行随机抽样的横断面观察研究。采用欧洲儿科牙科学会（EAPD）（2003年）标准对所有乳牙的EH进行评分。由一名经验丰富的检查者对研究人群进行全面临床检查。数据以患病率、类型、程度和分布形式表示。使用学生t检验和方差分析（ANOVA）对受影响受试者中不同类型病变的患病率和分布进行进一步分析。
报告的总体患病率为7.51%（71/948）。据报告，每名受试者受影响的牙齿平均为2.75 ± 1.735颗。最常见的病变是乳白垩色不透明（P = 0.002），而40.85%（29/71）的受影响受试者出现萌出后牙体破坏（PEB）。
乳牙列中EH的患病率为7.51%。需要在世界其他地理位置进一步开展研究，以明确患病率以及与磨牙切牙矿化不足（MIH）的可能联系。
