AB  - INTRODUCTION: Patients' perceptions and expectations regarding their appearance 
      play a significant role in treatment planning. The purpose of this study was to 
      compare the perceptions of orthodontists, general dentists, and laypersons 
      regarding smile esthetics after symmetrical and asymmetrical alterations in 
      anterior teeth and their supporting tissues. MATERIALS AND METHODS: Alterations 
      were made in the crown length, crown width, midline diastema, and gingiva-to-lip 
      relationship of the maxillary anterior teeth in the close-up photograph of a 
      woman's smile. The attractiveness of the smile in the original image and in each 
      of the modified images were assessed by orthodontists (n=40), dentists (n=40), 
      and laypersons (n=40) and scored using a visual analog scale (VAS). The mean VAS 
      scores were calculated for each photograph. ANOVA was used for comparisons 
      between photographs and between groups. To determine threshold levels at which 
      each group discriminated between esthetic and less esthetic dental features were 
      determined by one-way ANOVA (F-test) followed by Newman-Keul's range test. 
      RESULTS: Orthodontists were found to be more critical when evaluating smile 
      images compared to general dentists and laypersons. Symmetrical or asymmetrical 
      alterations in the mesio-distal width of the lateral incisor of up to 2 mm was 
      not perceived as unesthetic by general dentists and laypersons. CONCLUSION: 
      Laypersons are more accepting of minor variations in anterior tooth size and 
      alignment than orthodontists.
