Overview

Cross-sectional study reveals that advanced dental training increases sensitivity to smile aesthetic variations in dental students, indicating clinical experience refines aesthetic judgment.

Key Points

To evaluate how dental education level affects the perception of smile aesthetics across various academic cohorts of dental students.
Enrolled 344 first- through fifth-year dental students divided into preclinical (years 1–3) and clinical (years 4–5) training levels in a cross-sectional design.
Assessed aesthetic perception using a 6-point numerical rating scale on standardized photographs digitally manipulated across six aesthetic parameters.
Analyzed score differences across the five academic years using one-way ANOVA or the Kruskal-Wallis test followed by post hoc pairwise comparisons.
Aesthetic perception scores significantly differed across academic years for maxillary central incisor length and midline diastema (p < 0.05).
Smile images displaying a 1-mm midline diastema received the lowest aesthetic ratings across all student cohorts.
Clinical students consistently demonstrated greater sensitivity in detecting smile aesthetic deviations compared to preclinical students.
