Summary
Automated software like PhotoGenic offers a new way to evaluate facial esthetics, but it rated participants as more attractive than human evaluators did. This tool is not yet suitable for dentistry due to its lack of focus on dental visibility.
Area of Science:
- Dentistry
- Facial Aesthetics
- Computer Vision
Background:
- Evaluating facial esthetics objectively is challenging.
- Automated software applications may provide an unbiased method for esthetic evaluation.
Purpose of the Study:
- To assess a smartphone application (PhotoGenic) as an objective tool for evaluating facial attractiveness.
- To determine the potential application of this tool in dentistry.
Main Methods:
- Frontal facial photographs of ten participants were analyzed using the PhotoGenic application.
- One hundred human raters evaluated the same participants' attractiveness.
- Statistical analyses investigated the influence of participant and rater demographics and expressions.
Main Results:
- PhotoGenic yielded significantly higher attractiveness scores (6.4 ±1.2) than human raters (4.9 ±1.8).
- Rater demographics (sex and occupation) influenced evaluations, while participant characteristics had less impact.
- Female raters tended to assign higher attractiveness scores.
Conclusions:
- The PhotoGenic application rated participants as more attractive than human evaluators.
- The application is currently unsuitable for objective evaluation in dentistry as it does not consider dental visibility, such as during a smile.

Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role...
