Abstract

Objective

This study aimed to evaluate the influence of enamel defects in anterior teeth associated with molar incisor hypomineralization (MIH) on peer perception of smile esthetics in children and adolescents.

Methods

A total of 288 children and adolescents aged 10–14 years from both public and private schools participated. Each participant evaluated standardized photographs of peers’ smiles, either showing MIH-related anterior enamel opacities or digitally altered to appear defect-free. Participants rated each image across four psychosocial domains: athletic ability, social competence, leadership potential, and academic performance. Independent-sample t-tests were used to compare ratings between smile types, and General Linear Models (GLMs) were applied to analyze the influence of evaluator-related variables such as age and gender.

Results

Digitally modified smiles received significantly higher ratings than unedited images for athletic ability (59.72 ± 0.86 vs. 50.94 ± 0.89; mean difference = 8.78, p < 0.001), social competence (52.62 ± 0.80 vs. 43.78 ± 0.81; difference = 8.84, p < 0.001), leadership potential (64.15 ± 0.84 vs. 56.44 ± 0.86; difference = 7.71, p < 0.001), and academic performance (62.52 ± 0.79 vs. 58.36 ± 0.83; difference = 4.16, p < 0.001). GLM analysis indicated that evaluator age and gender were stronger predictors than smile type, with older children and female evaluators demonstrating greater esthetic sensitivity (p < 0.05).

Conclusion

MIH-related enamel defects in anterior teeth negatively affect peer perception, but evaluator-related factors such as age and gender play an important role in shaping social judgments.

Clinical significance

This study demonstrates that enamel defects in anterior teeth caused by MIH not only present a clinical challenge but also influence how children are perceived by their peers in terms of social attributes.

前牙磨牙低矿化相关牙釉质缺损对儿童青少年微笑审美同伴感知的影响。

目的：探讨前牙釉质缺损伴磨牙切牙矿化程度降低对儿童青少年微笑审美同伴感知的影响。方法：对288名10 ~ 14岁的公立和私立学校儿童和青少年进行调查。每个参与者都评估了同龄人的标准化微笑照片，要么显示与mih相关的前牙釉质不透明，要么通过数字处理使其看起来没有缺陷。参与者从四个社会心理领域对每张图片进行打分：运动能力、社会能力、领导潜力和学习成绩。采用独立样本t检验比较不同微笑类型的评分，采用一般线性模型（General Linear Models, GLMs）分析评价者相关变量（如年龄和性别）的影响。结果：在运动能力（59.72±0.86 vs. 50.94±0.89，平均差值 = 8.78,p < 0.001）、社交能力（52.62±0.80 vs. 43.78±0.81，差值 = 8.84,p < 0.001）、领导潜力（64.15±0.84 vs. 56.44±0.86，差值 = 7.71,p < 0.001）和学习成绩（62.52±0.79 vs. 58.36±0.83，差值 = 4.16,p < 0.001）方面，数字修改后的笑容评分明显高于未编辑后的照片。GLM分析显示，评价者的年龄和性别比微笑类型具有更强的预测作用，年龄较大的儿童和女性评价者表现出更高的审美敏感性（p < 0.05）。结论：前牙mih相关性牙釉质缺损对同伴知觉有负向影响，但年龄、性别等评价者相关因素对社会判断有重要影响。临床意义：本研究表明，MIH引起的前牙牙釉质缺损不仅对临床提出了挑战，而且影响了同龄人对儿童社会属性的认知。

期刊介绍： The Journal of Dentistry has an open access mirror journal The Journal of Dentistry: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The Journal of Dentistry is the leading international dental journal within the field of Restorative Dentistry. Placing an emphasis on publishing novel and high-quality research papers, the Journal aims to influence the practice of dentistry at clinician, research, industry and policy-maker level on an international basis. Topics covered include the management of dental disease, periodontology, endodontology, operative dentistry, fixed and removable prosthodontics, dental biomaterials science, long-term clinical trials including epidemiology and oral health, technology transfer of new scientific instrumentation or procedures, as well as clinically relevant oral biology and translational research. The Journal of Dentistry will publish original scientific research papers including short communications. It is also interested in publishing review articles and leaders in themed areas which will be linked to new scientific research. Conference proceedings are also welcome and expressions of interest should be communicated to the Editor.
