The aim of this study was to study the effect of Molar Incisor Hypomineralisation (MIH) on Oral Health-Related Quality of Life (OHRQoL) in children at the mixed dentition stage and correlate it with their caries experience.
One hundred two children aged from 8 to 10 years were recruited, 51 with MIH and 51 as control. Caries experience was recorded using DMFT/deft and ICDAS II. MIH-TNI index was used for classifying MIH severity. CPQ with its Arabic version was used to evaluate OHRQoL. Mann-Whitney U test and Kruskal-Wallis test were used for comparisons (p ≤ 0.05).
The mean value for CPQ in MIH group was 24.67 (±11.84; median 23; range 6-55) in comparison to 21.04 (±12.3; median 18; range 2-54) for the control group, with no significant difference between groups (p = 0.109). A significantly higher value (p = 0.011) was recorded in patients with MIH-TNI 4 mean 32.16 (±13.9; median 35; range from 7 to 55) in comparison to other categories of MIH.
Children with and without MIH, with similar caries experience showed no difference in OHRQoL. However, the presence of the severe form of MIH including hypersensitivity and enamel disintegration negatively impacted those children's OHRQoL.
本研究旨在探讨混合牙列期儿童磨牙釉质发育不全（MIH）对口腔健康相关生活质量（OHRQoL）的影响，并将其与龋齿经历相关联。
招募了102名8至10岁的儿童，其中51名患有MIH，51名作为对照。使用DMFT/deft和ICDAS II记录龋齿经历。MIH-TNI指数用于对MIH严重程度进行分类。使用阿拉伯语版的儿童口腔健康影响程度量表（CPQ）评估OHRQoL。采用曼-惠特尼U检验和克鲁斯卡尔-沃利斯检验进行比较（p≤0.05）。
MIH组CPQ的平均值为24.67（±11.84；中位数23；范围6 - 55），而对照组为21.04（±12.3；中位数18；范围2 - 54），两组之间无显著差异（p = 0.109）。与其他MIH类别相比，MIH-TNI 4级患者的CPQ值显著更高（p = 0.011），平均值为32.16（±13.9；中位数35；范围7至55）。
龋齿经历相似的患MIH和未患MIH的儿童在OHRQoL方面无差异。然而，包括牙齿敏感和釉质崩解在内的严重形式的MIH对这些儿童的OHRQoL产生了负面影响。
