Abstract

  Background: Facial aesthetics plays a crucial role in social communication; however, aesthetic perception is inherently subjective and influenced by demographic factors. Objectives: 1. To assess aesthetic perception of the facial profile among students and staff; 2. To determine the association between demographic factors and this aesthetic perception. Materials and methods: A cross-sectional descriptive study was conducted on 803 participants (students and staff) at Can Tho University of Medicine and Pharmacy from May to October 2025. Data were collected using an online questionnaire incorporating standardized images representing 13 gradations of lower lip position (from −6 mm to +6 mm) relative to the esthetic E-line. Statistical analyses were performed using SPSS version 27.0. The Kruskal–Wallis test and ordinal logistic regression were applied, with a significance level set at p≤0.05. Results: The study population consisted of 57.3% females and 42.7% males. The majority of participants preferred a neutral or slightly retruded lower lip position. Gender had a strong influence on aesthetic perception (p<0.001), with males being 1.795 times more likely than females to prefer a more protrusive lower lip (OR=1.795; 95% CI: 1.401–2.300). The participant group also showed a statistically significant difference (p=0.04), as postgraduate students tended to favor a more protrusive lower lip. In contrast, training specialty and duration of study did not demonstrate statistically significant associations with aesthetic perception (p>0.05). Conclusions: Aesthetic perception of lower lip retrusion is clearly influenced by gender and generational characteristics, yet remains stable and is not significantly altered by the length or specialty of medical training.
