The aim of this study was to investigate the relationship between personality profiles and perception of maxillary midline diastema (MMD) among laypeople.
Materials and methods
Hundred total of 200 laypeople (100 females and 100 males, mean age = 28.8 ± 5.5 years) were recruited in this cross-sectional study. They were asked to rate the attractiveness of two digital photographs of ideal smile with 1 and 2 mm MMD on a visual analog scale (VAS) from 0 to 10. Participants' personality and psychological profiles were assessed via neuroticism.extraversion.openness five-factor inventory. The statistically significant levels were set at p ≤ 0.05.
Results
The mean VAS scores were 5.7 (± 2.1) and 4.3 (± 2.0) for 1 and 2 mm MMD respectively. The participants rated the attractiveness of 1 mm diastema better than the attractiveness of 2 mm diastema (p < 0.001). Females showed no difference in rating diastema attractiveness in comparison with males (p > 0.05). Participants (from both genders) with higher neuroticism scores rated 1 and 2 mm diastemas as less attractive than those with lower neuroticism scores (p ≤ 0.001).
Conclusion
Psychological profiles (high neuroticism) might be associated with negative perceptions of attractiveness of MMD.
