Perception of smile attractiveness among Egyptian population

Aim of the study: This study aims to evaluate the standards and perceptions of smile attractiveness within the Egyptian population. This is important for use in clinical and academic settings.
Materials and methods: Two males and two females smiling photos were digitally altered to create Buccal corridors of four sizes (2%, 10%, 22%, and 34%), and spacing in the lateral incisor area was created (1.5, 2, 3mm) increments. (VAS) was used to measure participants' perceptions of smile among 60 participants, including Orthodontists, dentists and laypeople.
Results: As the width of buccal corridors increased, VAS scores consistently decreased. At 10%, Orthodontists gave lesser scores than both dentists and laypersons. But at 34% all groups scored smile as unattractive. Starting from 1.5 mm, both orthodontists and dentists detected the spacing, at 2mm spacing the majority rated the smile as unattractive. Conclusions: Buccal corridors and dental spacing greatly influences smile perceptions and attractiveness among orthodontic professionals, dentists, and laypeople. Orthodontists were more sensitive to moderate changes in the buccal corridors and spacing. Asymmetries should be discussed with patients before treatment. Orthopedic or surgical expansion of the maxilla should be considered.
