To compare the amount of maximal gingival display among four different facial expressions and evaluate the golden percentage in a section of North Indian population.
Neither smile type (requested or Duchenne) revealed a significantly greater amount of gingival display above the maxillary central or lateral incisors, but the grimace of disgust and funnel-shaped expressions did. At the central and lateral incisors, the grimace of disgust and funnel-shaped expressions produced the greatest amounts of gingival display. At the maxillary canines and the first premolars, both smiles (requested and Duchenne) exhibited the largest amount of gingival display of the four facial expressions.
Conclusion
There exists a difference in gingival display among four different facial expressions over each tooth visible, and the golden percentage was found to be present in more than 99% of the subjects studied.
Clinical significance
This article considers gingival display as an important factor in rehabilitating esthetic smiles, and proposes the concept of the golden percentage as a more useful application in diagnosing and developing symmetry, dominance, and proportion for esthetically pleasing smiles.
