The harmonious shade matching of restorations with adjacent natural teeth is a prerequisite for a successful esthetic restoration. Color is a combined effect of the physical properties of an object, the light source, and the perception of the observer. The interpretation of color is influenced by both the physiological and psychological health of an individual. It is critical to understand the influence of an individual's psychological state on the shade selection procedure to achieve better shade matching and post-treatment patient counseling. The aim of this study was to evaluate the influence of personality on tooth shade selection capability.
Two porcelain fused to metal (PFM) discs were fabricated. A reference shade was determined using a spectrophotometer (Vita Easyshade, Vita). The personalities of volunteers were identified using a Myers- Briggs Type Indicator (MBTI) questionnaire. The volunteers visually identified the shade of the two PFM discs under a controlled light source. The mean color difference was determined between the visual and the spectrophotometer values. The data thus obtained was statistically analyzed with Kruskal-Wallis and post-hoc comparison tests to ascertain the difference between the groups.
The groups that performed better in tooth shade selection were ENTJ (2.923 ± 2.36), ISTJ (3.086 ± 2.56), ENFJ (3.197 ± 2.936), and ESTJ (3.431± 2.78). The groups INTP (9.383 ± 3.30), ISTP (9.133 ± 3.44), ISFP (8.737 ± 2.81), and INTJ (8.480 ± 3.35) showed poor tooth shade selection ability. The Kruskal- Wallis test showed lower mean rank for group ENTJ (89.75), followed by ISTJ (92.25), and ENFJ (94.80).
Within the limitations of this study, it was concluded that there was a statistically significant difference between the different personalities with regard to tooth shade selection ability.
修复体与相邻天然牙的和谐颜色匹配是成功进行美学修复的前提条件。颜色是物体物理特性、光源以及观察者感知的综合效应。颜色的解读受到个体生理和心理健康的影响。了解个体心理状态对比色过程的影响对于实现更好的颜色匹配和治疗后患者咨询至关重要。本研究的目的是评估性格对牙齿比色能力的影响。
制作了两个烤瓷熔附金属（PFM）盘。使用分光光度计（Vita Easyshade，维他公司）确定参考色。通过迈尔斯-布里格斯类型指标（MBTI）问卷确定志愿者的性格。志愿者在可控光源下目视识别两个PFM盘的颜色。确定目视值与分光光度计值之间的平均色差。对由此获得的数据进行Kruskal-Wallis检验和事后比较检验，以确定组间差异。
在牙齿比色方面表现较好的组是ENTJ（2.923±2.36）、ISTJ（3.086±2.56）、ENFJ（3.197±2.936）和ESTJ（3.431±2.78）。INTP（9.383±3.30）、ISTP（9.133±3.44）、ISFP（8.737±2.81）和INTJ（8.480±3.35）组的牙齿比色能力较差。Kruskal-Wallis检验显示ENTJ组的平均秩次较低（89.75），其次是ISTJ组（92.25）和ENFJ组（94.80）。
在本研究的局限性范围内，得出结论：不同性格在牙齿比色能力方面存在统计学上的显著差异。
