Abstract

This analytical cross-sectional study evaluated the perception of black triangles (BT) and examined the relationships between the perception of BT, personality factors, different educational backgrounds and demographic factors. 435 participants were included and divided into four groups: dentists, clinical (4th and 5th year) dental students, pre-clinical (3rd year) dental students, and laypeople. Participants' perception of the attractiveness of smile profiles of maxillary and mandibular anterior dentition with BT was rated using a ten-point VAS scale with 0 being the least, and 10 being the most attractive smile profile. The personality was assessed using the NEO-FFI personality questionnaire. The smile profile with multiple large BT was rated the least attractive for the maxillary (mean = 3.6) and mandibular (mean = 3.9) tested profiles. The smile profile without BT was rated the most attractive for the maxillary (mean = 9.1) and mandibular (mean = 8.8) tested profiles. The dental professionals perceived the maxillary smile profile with multiple large BT as less attractive than the non-dental participants (t = - 2.715, P = 0.007). Being a male, having dental education, having lower Neuroticism scores, as well as having higher Openness, Agreeableness, Conscientiousness, and Extraversion scores predicted and contributed more towards perceiving various tested smile profiles as more attractive. These findings show that black triangles negatively impacts the perception of smile attractiveness, and that personality traits and having dental education impact the perception of smile attractiveness for smiles with black triangles.

摘要

本分析性横断面研究评估了对黑三角(BT)的认知,并研究了对 BT 的认知、人格因素、不同教育背景和人口统计学因素之间的关系。纳入 435 名参与者,并将其分为四组:牙医、临床(第 4 年和第 5 年)牙科学生、临床前(第 3 年)牙科学生和非专业人士。使用 10 分制视觉模拟量表(0 分表示最不吸引人,10 分表示最吸引人的微笑曲线)评估参与者对上颌和下颌前牙 BT 微笑曲线的吸引力的认知。使用 NEO-FFI 人格问卷评估人格。对于上颌(平均=3.6)和下颌(平均=3.9)测试的微笑曲线,具有多个大 BT 的微笑曲线被评为最不吸引人。没有 BT 的微笑曲线被评为上颌(平均=9.1)和下颌(平均=8.8)测试的微笑曲线最吸引人。与非牙科参与者相比,牙科专业人员认为上颌多个大 BT 的微笑曲线吸引力较低(t=-2.715,P=0.007)。男性、具有牙科教育背景、具有较低的神经质分数,以及具有较高的开放性、宜人性、尽责性和外向性分数,预测并更多地影响对各种测试的微笑曲线的吸引力的认知。这些发现表明,黑三角对微笑吸引力的认知产生负面影响,并且人格特质和牙科教育背景对具有黑三角的微笑吸引力的认知产生影响。
