目的：探讨磨牙-切牙矿化不良（MIH）与釉质发育不良的关系。研究设计：样本包括311名年龄在12岁至18岁之间的正畸患者，分为两组：MIH患者（109）和非MIH患者（202）。MIH和釉质发育不全通过全景X线片和口内照片进行诊断，然后根据改良的EAPD评分标准对MIH受影响的患者进行临床检查。采用卡方检验和t检验评估性别、年龄和人种的组间比较。使用Fisher精确检验比较各组是否存在釉质发育不全，并计算校正比值比（OR）。结果：MIH与釉质发育不全有关。与对照组（0.49%）相比，MIH患者中釉质发育不全的患病率（5.5%）显著更高。MIH病变增加12.45倍的风险有釉质发育不全。结论：MIH患者有较高的釉质发育不良的患病率，这些缺陷似乎有相同的病因。
Objective: To investigate the association between molar-incisor hypomineralization (MIH) and enamel hypoplasia. Study design: The sample consisted of 311 orthodontic files of patients aged between 12 and 18 years, divided into two groups: patients with MIH (109) and without MIH (202). MIH and enamel hypoplasia were diagnosed via panoramic radiographs and intraoral photographs, followed by clinical examination of the MIH-affected patients as per the modified EAPD scoring criteria. Chi-square test and t test were used to assess intergroup comparisons regarding sex, age and race. Fisher's Exact test was used to compare the groups regarding the presence of enamel hypoplasia and the Adjusted Odds Ratios (OR) were calculated. Results: There was an association between MIH and enamel hypoplasia. The prevalence of enamel hypoplasia (5.5%) was significantly higher in patients with MIH compared to the control group (0.49%). MIH lesions increase 12.45-fold the risk of having enamel hypoplasia. Conclusion: Patients with MIH have a higher prevalence of enamel hypoplasia and these defects seem to share the same etiological factor.
