Comparing the Effect of Dental Education on Aesthetic Perception in Different Educational Groups

Abstract

Background: Smile aesthetics plays a fundamental role in facial attractiveness and is an essential component of contemporary aesthetic dentistry. Dental education is expected to improve students' ability to recognize subtle variations in smile aesthetics. This study aimed to evaluate the effect of dental education level on the aesthetic perception of different smile characteristics among dental students.
Materials and Methods: A cross-sectional study was conducted with 344 first- to fifth-year dental students. Standardized photographs of an aesthetically acceptable female smile were digitally modified using Adobe Photoshop CC 2018 to create variations in six aesthetic parameters: golden proportion, gingival display, maxillary central incisor length, dental midline deviation, midline diastema, and anterior crowding. Participants evaluated each image using a 6-point numerical rating scale (0= not aesthetically pleasing, 5= extremely aesthetically pleasing). First-, second-, and third-year students were classified as preclinical, whereas fourth- and fifth-year students were classified as clinical students for descriptive comparisons. Statistical analyses were primarily performed across the five academic years. Data were analyzed using one-way analysis of variance (ANOVA) or the Kruskal-Wallis test, as appropriate, followed by post hoc pairwise comparisons.
Results: Aesthetic perception tended to improve with increasing years of dental education. Statistically significant differences among the academic years were observed in the evaluation of maxillary central incisor length and midline diastema (p<0.05). Images with a 1-mm midline diastema received the lowest aesthetic scores across all groups. Overall, clinical students demonstrated greater sensitivity to smile esthetic deviations than preclinical students.
Conclusions: Dental education positively influences the perception of smile aesthetics, with aesthetic sensitivity increasing throughout the educational process. Clinical experience appears to enhance students' ability to identify deviations in key aesthetic parameters. These findings may contribute to the improvement of aesthetic dentistry education and clinical decision-making.
