To investigate the relationship between aesthetic perception and molar incisor hypomineralization (MIH) in schoolchildren aged 8-12 years.
The study included 467 pupils enrolled in elementary schools. Once authorization was received, the students were examined for DMFT and dmft indexes (WHO criteria), and for MIH (EAPD criteria). The aesthetic perceptions were verified by the Child Perceptions Questionnaire About Tooth Appearance (CQATA), a questionnaire divided into several items, including physical, psychological and social domains; perception about tooth pleasantness, tooth alignment, tooth discoloration and tooth health; and reported pleasant colour. Data analysis was carried out using descriptive statistics, the Chi-square, the Mann-Whitney and the Kruskal-Wallis tests, and linear regression at a significance level of 0.05.
The tooth health perception was worse when the child had MIH, and the tooth alignment and tooth discoloration perceptions, when MIH affected the incisors. The number of teeth affected by MIH was associated with higher averages in the tooth discoloration perception.
Children with MIH showed more negative perceptions toward tooth health, tooth alignment and tooth discoloration. However, none of the clinically investigated variables negatively impacted the reported pleasant colour question.
调查 8-12 岁学龄儿童审美感知与磨牙牙釉质发育不全（MIH）之间的关系。
本研究纳入了 467 名小学生。在获得授权后，按照世界卫生组织（WHO）标准检查学生的 DMFT 和 dmft 指数，按照欧洲儿童牙科学会（EAPD）标准检查 MIH。使用儿童口腔外观感知问卷（Child Perceptions Questionnaire About Tooth Appearance，CQATA）评估儿童的审美感知，该问卷分为若干项目，包括身体、心理和社会领域；对牙齿美观、牙齿排列、牙齿变色和牙齿健康的感知；以及报告的喜爱颜色。采用描述性统计、卡方检验、Mann-Whitney 检验和 Kruskal-Wallis 检验以及线性回归进行数据分析，检验水准为 0.05。
患有 MIH 的儿童对牙齿健康的感知更差，而 MIH 影响切牙时对牙齿排列和牙齿变色的感知更差。MIH 累及的牙齿数量与牙齿变色感知的平均值较高相关。
患有 MIH 的儿童对牙齿健康、牙齿排列和牙齿变色的感知更负面。然而，在临床研究的变量中，没有任何一个变量对报告的喜爱颜色问题产生负面影响。
