To evaluate the effect of emotional states on reproducibilities of rest position, social and spontaneous smiles, and speech.
A total of 30 individuals aged 18-22 years were included (mean age; 19.03 years ±1.03). Three emotional states were determined: amusing, sadness, and neutral. The participants watched three different videos in 3 sessions on the same day. After each video, the participants completed a questionnaire to assess their mood. The rest position, social and spontaneous smiles, and speech recordings were gathered from the participants using videographic method. Measurements were made for each function. The Friedman test, One-Way ANOVA, Kruskal-Wallis test was performed for statistical evaluations, and intra-observer correlation coefficients and Bland-Altman Limits of Agreement were calculated.
In spontaneous smiles, there were significant differences between amusing and sadness in the smile height (p=0.020); amusing and sadness in the lower lip thickness (p=0.029). In social smiles there was a significant difference between amusing and sadness in the maxillary incisor display (p=0.006). There were no statistically significant differences in the rest position, but clinically significant differences were observed in some participants. In speech, a significant difference was found between amusing and sadness in the distance between the upper lip and subnasal (p=0.035).
The reproducibility of social and spontaneous smiles was influenced by various emotional states. However, the rest position exhibits higher reproducibility than social and spontaneous smiles in all emotional states.
评估情绪状态对静息位、社交性微笑与自发性微笑及言语的可重复性的影响。
纳入30名年龄在18至22岁之间的个体（平均年龄19.03岁±1.03）。确定了三种情绪状态：愉悦、悲伤和中性。参与者在同一天分三个阶段观看三段不同的视频。每段视频观看后，参与者完成一份问卷以评估其情绪。使用摄像方法收集参与者的静息位、社交性微笑与自发性微笑以及言语记录。对每个功能进行测量。采用Friedman检验、单因素方差分析、Kruskal-Wallis检验进行统计学评估，并计算观察者内相关系数和Bland-Altman一致性界限。
在自发性微笑中，愉悦与悲伤状态下的微笑高度存在显著差异（p = ０.０２０）；愉悦与悲伤状态下的下唇厚度存在显著差异（p = ０.０２９）。在社交性微笑中，愉悦与悲伤状态下的上颌切牙暴露度存在显著差异（p = ０.００６）。静息位方面无统计学显著差异，但部分参与者存在临床显著差异。在言语方面，愉悦与悲伤状态下上唇与鼻下之间的距离存在显著差异（p = ０.０３５）。
社交性微笑与自发性微笑的可重复性受多种情绪状态影响。然而，在所有情绪状态下，静息位的可重复性高于社交性微笑与自发性微笑。
