Abstract


Introduction Smile evaluation has become an integral part of the clinical examination. The objectives of this study were to evaluate posed smile in males and females for Morley’s ratio, buccal corridors, smile arc and difference in esthetic perception between dental specialists and laypersons.

Methods 40 subjects (20 males and 20 females) were chosen and frontal smiling photographs of the subjects were cropped with the vertical limit from the nose tip to the soft tissue pogonion and transverse limit between perpendicular lines drawn down from
zygomatic prominence on each side. The pictures were used to evaluate buccal corridor widths, Morley’s ratio, the consonance of the smile and attractiveness of the posed smile as perceived by dental specialists and laypersons using VAS scale.

Results The Morley’s ratio was found to be more in females than males and so were the consonant smile arcs. There was a high correlation between right and left buccal corridor measurements in both sexes. There was no difference in perception of dental specialists and laypersons.

Conclusions Consonant smile arcs result in more aesthetic smiles while buccal corridors seem to have no effect. Better VAS scores were observed in subjects with increased Morley’s ratio.
