Abstract Objective:To evaluate the aesthetic perception of digitally simulated smile variations across five parameters; gingival display, midline diastema, midline deviation, crown angulation, and anterior tooth alignment, comparing the preferences and sensitivity of laypersons, orthodontists, and general dentists.
Materials and Methods: Standardized smile photographs were digitally altered to produce three variations (ideal, mild, moderate) for each parameter. The images were presented to orthodontists, general dentists, and laypersons, who rated esthetics using a 5-point Likert scale and selected the most esthetic option. Statistical analysis was performed to assess intergroup differences in esthetic ratings.
Results: Orthodontists demonstrated the highest sensitivity to smile discrepancies, particularly gingival display and midline diastema, rating deviations less esthetic. General dentists showed moderate sensitivity, while laypersons were more tolerant of minor midline shifts and crown angulation changes. Anterior tooth alignment exerted the strongest influence on esthetic ratings, with severe crowding consistently perceived as least attractive.
Conclusion: Perceptions of smile esthetics differ significantly among professional and lay observers. While professionals favour smiles closer to ideal standards, laypersons exhibit broader acceptance of mild discrepancies. Recognition of these differences is essential for aligning clinical objectives with patient expectations in contemporary orthodontic and esthetic treatment planning.
