Comparative evaluation of the accuracy and reproducibility of indigenously developed profile, smile and dento-gingival (PSD) Coding and grading system for facial esthetics amongst dental students and practitioners
Background: Facial esthetics play a crucial role in personal and professional interactions, influencing self-confidence and social perception. Standardized assessment methods are crucial for consistency in clinical evaluations and treatment planning. The purpose of this study was to compare the accuracy and reproducibility of Profile, Smile and Dento-gingival (PSD) coding and grading system for facial esthetics amongst dental students and practitioners, examining the impact of experience level on aesthetic evaluation.
Materials and Methods: Three standard photographs (extra-oral frontal smile, profile, and intra-oral frontal) were digitally manipulated to create 10 sets, each highlighting different facial features. These sets were coded and graded using the PSD system. A total of 100 examiners were divided into four groups: BDS interns (BS), BDS practitioners (BP), MDS (Orthodontics) students (MS), and MDS (Orthodontics) practitioners (MP) to evaluate photographs. One-way ANOVA with Tukey’s post hoc test compared group scores, while intra-class correlation coefficient (ICC) and Cohen’s kappa statistics assessed intra- and inter-examiner reliability. The level of significance was set at P<0.05.
Results: The MP group achieved the highest overall score (114.88 ± 11.74), while BS scored the lowest (85.2 ± 13.20). MP showed the highest intra-examiner reliability (0.974) and BS the lowest (0.832). Inter-examiner reliability was strongest in MP (0.69) and weakest in BS (0.56).
Conclusion: MDS Orthodontics practitioners demonstrated the highest accuracy and reproducibility, likely due to their specialized training and experience. In contrast, BDS interns had the lowest accuracy, emphasizing the importance of expertise in facial esthetics evaluation.
