To evaluate the relationship of the perioral soft tissues and teeth to attractive smiles.


Twenty frontal photographs of female celebrities were selected from the internet and were rated by a panel consisting of laymen, a Prosthodontist, a Community dentist and an Orthodontist into the following categories: (1) poor, (2) fair, (3) good, (4) very good and (5) excellent. These scores were averaged and the smiles were analysed for buccal corridor, smile line ratio, smile symmetry and smile index.


There was a significant negative correlation between average rating and buccal corridor (r =– 0.481, p = 0.032 < 0.05) and smile index (r = – 0.624, p = 0.003 < 0.05) respectively. A significant positive correlation was seen between average ratings and smile symmetry (r = 0.461, p = 0.041 < 0.05).No significant correlation was found between average ratings and smile line ratio(r = – 0.163, p =0.492 > 0.05).


A symmetric smile with a narrow buccal corridor and a low smile index increases the esthetic appearance of a smile. However, smile line ratio does not affect the attractiveness of a smile.
