Assess the prevalence and severity of molar incisor hypomineralization (MIH) in children 6- to 12-year-old and correlate MIH severity with the complexity of treatment demands.
Between March and October 2023, 2,136 children were screened for MIH by two calibrated examiners. MIH severity was categorized in mild, moderate, severe, and very severe. Treatment requirements were categorized in basic, intermediate, and complex.
The prevalence of MIH was 15.5% (n = 331), 158 (47.7%) mild/moderate and 173 (52.3%) severe/very severe. Among the 126 children with atypical caries/restoration, cusp involvement was observed in 60.3%, endodontic treatment was necessary in 24.6%, only 15% needed restorations limited to two tooth surfaces with no cusp involvement. Extraction due to MIH was observed in 2.7%.
The prevalence of MIH was in accordance with previous literature. Whenever a restorative treatment was necessary, it often involved multiple tooth surfaces and cusps. The complexity of treatment demands increased with age. It is necessary that oral health policymakers pay special attention to children with MIH to ensure appropriate treatment.
MIH represents a challenge, especially severe cases with enamel post-eruptive breakdown and caries, requiring extensive restorations. MIH prevalence was assessed in a considerable large sample and the correlation between MIH severity and the complexity of treatment demands was analyzed. More than half of children exhibiting atypical caries/restorations required complex restorative treatment, involving multiple tooth surfaces and cusps. The manuscript prompts a reflection on the importance of evaluating whether the restoration will extend to cusp areas before determining the appropriate technique and material for treatment.
评估6至12岁儿童磨牙切牙矿化不全（MIH）的患病率和严重程度，并将MIH严重程度与治疗需求的复杂性相关联。
在2023年3月至10月期间，由两名经过校准的检查人员对2136名儿童进行MIH筛查。MIH严重程度分为轻度、中度、重度和极重度。治疗需求分为基本、中级和复杂。
MIH的患病率为15.5%（n = 331），其中158例（47.7%）为轻度/中度，173例（52.3%）为重度/极重度。在126例患有非典型龋齿/修复的儿童中，60.3%观察到牙尖受累，24.6%需要进行根管治疗，只有15%需要仅限于两个牙面且无牙尖受累的修复。因MIH导致的拔牙率为2.7%。
MIH的患病率与先前文献一致。每当需要进行修复治疗时，通常涉及多个牙面和牙尖。治疗需求的复杂性随年龄增加。口腔健康政策制定者有必要特别关注患有MIH的儿童，以确保进行适当治疗。
MIH是一项挑战，尤其是釉质萌出后破坏和龋齿的严重病例，需要广泛的修复。在一个相当大的样本中评估了MIH患病率，并分析了MIH严重程度与治疗需求复杂性之间的相关性。超过一半表现出非典型龋齿/修复的儿童需要复杂的修复治疗，涉及多个牙面和牙尖。该手稿促使人们反思在确定适当的治疗技术和材料之前评估修复是否会延伸至牙尖区域的重要性。
