Smile attractiveness of Persian women after orthodontic treatment

Abstract

Achieving a balanced, attractive smile is an important goal in contemporary orthodontics. This study aimed to assess the smile attractiveness of Persian women after orthodontic treatment. In this descriptive-analytical study, frontal-view photographs were taken of posed smiles of 100 Persian women 3months after completion of their orthodontic treatment. A total of 153 laypeople aged over 15years were requested to score each smile in terms of attractiveness using a visual analogue scale (1-10). Next, 25 photographs that acquired the lowest score (group A) and 25 photographs that acquired the highest score (group B) were chosen and evaluated by 3 orthodontists regarding parameters related to an attractive smile. Data were analyzed using SPSS version18. The mean buccal corridor space in group A was significantly greater than that in group B (P=0.004). The correlation of lip line and study group was significant such that 60% of patients in group B had a moderate lip line (P=0.005). The difference in other parameters was not significant between the 2 groups (P>0.05). The buccal corridor space and lip line are important factors affecting smile attractiveness of Persian women. According to the opinion of the laypeople, smaller buccal corridor space and moderate lip line yield a more attractive smile. Thus, these parameters should be taken into account in the orthodontic treatment of Persian women.
