BACKGROUND
Molar incisor hypomineralization (MIH) is one of the most common developmental disturbances that dental practitioners encounter, which may influence the child's quality of life and can impact their future dental health.
AIM
To determine prevalence and treatment needs of MIH in children of Lucknow.
MATERIALS AND METHODS
A total of 800 children aged 7 to 9 years were clinically screened for the presence of MIH. All demographic details were filled in by the examiner in communication with the parents, and examination was performed using the Würzburg MIH concept.
RESULTS
The overall prevalence of MIH in the children examined was 5.12%. A higher prevalence was found in males (7%) than in females (3.25%). The distribution of MIH was higher in the mandibular arch than in the maxillary arch. Mandibular molars were the most affected teeth, followed by maxillary incisors, and the least affected teeth were maxillary molars. On the basis of severity, 55.14% of teeth with MIH had no breakdown or hypersensitivity followed by 30.14% of teeth with hypersensitivity but no breakdown, and 7.35% of teeth had both hypersensitivity and breakdown. Based on severity, in 39.70% of teeth, the intervention suggested was fluoridated toothpaste, casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) remineralizing agent, and varnish application. This was followed by the application of sealants and low-viscosity glass ionomer cement (GIC) in 38.97% of teeth, and in 7.35% of teeth, short- and long-term restorations, including stainless steel crown (SSC), were recommended.
CONCLUSION
Prevalence of 5.12% was observed in children of Lucknow city. The characteristics of MIH defects were predictive of the treatment of the affected first permanent molars and incisors and can guide their management.

背景
磨牙症伴切牙矿化不全（MIH）是牙科医生遇到的最常见的发育障碍之一，可能会影响儿童的生活质量，并对其未来的口腔健康产生影响。
目的
确定勒克瑙市儿童中MIH的患病率和治疗需求。
材料与方法
对800名7至9岁的儿童进行临床检查，以筛查是否存在MIH。所有人口统计学细节均由检查人员与家长沟通后填写，并使用维尔茨堡MIH概念进行检查。
结果
接受检查的儿童中MIH的总体患病率为5.12%。男性患病率（7%）高于女性（3.25%）。MIH在下颌牙弓中的分布高于上颌牙弓。下颌磨牙是受影响最严重的牙齿，其次是上颌切牙，受影响最小的牙齿是上颌磨牙。根据严重程度，55.14%的MIH牙齿没有破损或过敏，其次是30.14%的牙齿有过敏但无破损，7.35%的牙齿既有过敏又有破损。根据严重程度，39.70%的牙齿建议的干预措施是使用含氟牙膏、酪蛋白磷酸肽-无定形磷酸钙（CPP-ACP）再矿化剂和涂擦护齿剂。其次是38.97%的牙齿使用窝沟封闭剂和低粘度玻璃离子水门汀（GIC），7.35%的牙齿建议进行短期和长期修复，包括使用不锈钢冠（SSC）。
结论
勒克瑙市儿童中MIH患病率为5.12%。MIH缺陷的特征可预测受影响的第一恒磨牙和切牙的治疗情况，并可指导其管理。
