Influence of personality on tooth shade determination

Objective: The color match of restorations with the natural teeth is a basic requirement for the aesthetic success of a treatment. Color arises as a combined effect of the physical properties of an object, the light source and the perception of the viewer. The interpretation of color depends on both the physical and mental health of the individual. Therefore, it is necessary to understand the influence of a person's mental state on the process of color determination. This improves both color matching and patient advice after treatment. The aim of this study was to investigate the influence of personality on the ability to determine tooth shade. Material and method: Two composite metal-ceramic disks (VMK) were produced. Their reference color value was determined with a spectrophotometer (Vita Easyshade, Vita). The personalities of the volunteer participants were determined using the Myers-Briggs Type Indicator (MBTI). The participants determined the color of the two VMK panes visually under controlled lighting. The mean color difference between the visual and the spectrophotometer values ​​was calculated and this data was analyzed using Kruskal-Wallis and post-hoc comparative tests to find differences between the groups. Results: The groups with the best results for color determination 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 only poor ability to determine tooth shade. The Kruskal-Wallis test gave lower mean ranks for the groups ENTJ (89.75), ISTJ (92.25) and ENFJ (94.80). Conclusion: Within the limits of this study, there were statistically significant differences between different personalities in their ability to determine tooth color.
