OBJECTIVE
To investigate the prevalence and severity of molar incisor hypomineralization (MIH).
MATERIALS AND METHODS
A sample of 2,864 students aged 8-12 years were selected from government and private schools in Chennai. MIH was diagnosed clinically based on the diagnostic criteria established by the European Academy of Pediatric Dentistry (EAPD) 2003.
RESULTS
A total of 277 children (9.7%) had MIH. There was statistically significant difference in prevalence related to age but there was no statistical difference in prevalence with respect to gender.
CONCLUSION
Prevalence of MIH was 9.7% in the child population residing in Chennai. Males and females were equally affected. The rate of occurrence and severity of MIH are more in the right mandibular first molar. The severity of MIH is more in molars compared to incisors (P < 0.001) and is more in government schools compared to private schools (P = 0.002).
目的
调查磨牙症切牙矿化不全（MIH）的患病率及严重程度。
材料与方法
从金奈的公立和私立学校选取了2864名8至12岁的学生作为样本。根据欧洲儿童牙科学会（EAPD）2003年制定的诊断标准，对MIH进行临床诊断。
结果
共有277名儿童（9.7%）患有MIH。患病率在年龄方面存在统计学显著差异，但在性别方面无统计学差异。
结论
居住在金奈的儿童中，MIH的患病率为9.7%。男性和女性受影响程度相同。右下颌第一磨牙的MIH发生率和严重程度更高。与切牙相比，磨牙的MIH严重程度更高（P < 0.001），与私立学校相比，公立学校的MIH严重程度更高（P = 0.002）。
