Özet

Objective: To evaluate the differences in aesthetically pleasing smiles and compare the smile arc parameters in males and females bydental specialists using photographs.Methods: The study was conducted on 500 North Indian subjects (Indo-Aryan race; 212 males and 288 females) aged 17-25 years(mean age, males=21.1 years; females=23.4 years), with reasonably pleasing smiles. The facial photographs were taken using a DSLRcamera. The standardized photographs were shown to 30 judges for evaluation and rated using the visual analog scale. The smileswere categorized into attractive, fair, and average. The quantification of the smile characteristics was done by using an objectivemethod that involved identifying consonant and non-consonant smiles.Results: The association between smile arc and smile attractiveness was significant (p=0.018) in females. The buccal corridor widthwas higher among those with fair to attractive smiles as compared with those with an average smile (p=0.018). Most subjects with anattractive smile had a smile arc parallel to the upper lip as compared with most subjects with a fair or average smile who did not havethe smile arc in parallel (p=0.006).Conclusion: Most females were in the fair to attractive category whereas most males were in the average to fair category. The buccalcorridor width was found to be higher among those with a fair to attractive smile as compared with those with an average smile. Therewas an association between smile arc and smile attractiveness in females.
