The aim of this study was to evaluate the impact of treating demarcated opacities in anterior teeth on the esthetic perception of children and their parents. Additionally, the masking effect was evaluated quantitively and qualitatively.
Thirty-nine patients, 8-18 years-old, presenting white-creamy opacity in permanent incisors were randomly allocated to test or control group. Test received resin infiltration and control received a placebo. The questionnaire Child's and Parent's Questionnaire about Teeth Appearance was used. The masking effect was quantitatively analyzed using the Lab System to calculate the color difference (ΔE) between the opacity and the surrounding enamel in Photoshop. Fisher's, Chi-square, Wilcoxon, Mann-Whitney tests and Spearman's correlation were applied to data analysis.
In the test group, a significant impact on physical and psychological domains in parents' and in social domain in parents' and children's perception was observed (p<0.05). Significant difference in ΔE between test and control groups was seen from 15 min of application onwards (p<0.05). After treatment, the mean ΔE was 4.07 (SD=3.07) in the test and 7.35 (SD=3.54) in the control group (p<0.01). One month later, the mean ΔE was 4.22 (SD=2.96) in the test and 6.06 (SD=2.52) in the control group (p<0.01). Total masking was seen only in the test group (p<0.01).
Aesthetic treatment of hypomineralization opacities in anterior teeth with resin infiltration impacted positively on parents and children. Resin infiltration reduced the color difference between opacities and sound enamel significantly after an application time of at least fifteen minutes.
Opacities in anterior teeth impact the self-image of children and parents negatively. This study demonstrated that 15 min resin infiltration can mask opacities in permanent incisors and recover social wellbeing. This minimally invasive approach can be offered to MIH children who report dissatisfaction with their incisors.
本研究旨在评估治疗前牙局限性不透明对儿童及其家长的美观感知的影响。此外，还评估了掩蔽效果的定量和定性。
将 39 名 8-18 岁的患者随机分为实验组和对照组，实验组接受树脂渗透治疗，对照组接受安慰剂。使用儿童和家长对牙齿外观的调查问卷。使用 Lab 系统在 Photoshop 中计算不透明度和周围釉质之间的颜色差异（ΔE）对掩蔽效果进行定量分析。Fisher、卡方、Wilcoxon、Mann-Whitney 检验和 Spearman 相关分析用于数据分析。
实验组中，家长在身体和心理方面以及家长和儿童在社会方面的感知均有显著影响（p<0.05）。实验组和对照组在应用 15 分钟后观察到ΔE 有显著差异（p<0.05）。治疗后，实验组的平均ΔE 为 4.07（SD=3.07），对照组为 7.35（SD=3.54）（p<0.01）。一个月后，实验组的平均ΔE 为 4.22（SD=2.96），对照组为 6.06（SD=2.52）（p<0.01）。仅在实验组中观察到完全掩蔽（p<0.01）。
用树脂渗透法对前牙的矿化不全性不透明进行美学治疗对家长和儿童均有积极影响。树脂渗透法在至少 15 分钟的应用时间后，显著降低了不透明度与正常釉质之间的颜色差异。
前牙的不透明度会对儿童和家长的自我形象产生负面影响。本研究表明，15 分钟的树脂渗透可以掩盖恒切牙的不透明度，并恢复社会幸福感。这种微创方法可以提供给对切牙不满意的 MIH 儿童。
