title: Assessment of objective and subjective measures as indicators for facial esthetics.
abstract: BACKGROUND
  The study mentioned was aimed to examine the contribution of the objective measures representing anterior-posterior (AP) and vertical characteristics, dental esthetics, or their combination that are used in daily orthodontic practice in the assessment of the facial esthetics.
  
  
  METHODS
  A panel of 64 laypersons evaluated the facial esthetics of 32 boys and 32 girls, stratified over four different angle classes, on a visual analog scale. The relationship between the objective parameters and facial esthetics was evaluated by the backward multiple regression analysis.
  
  
  RESULTS
  Dental esthetics, expressed by the esthetic component of the index of orthodontic treatment need (AC/IOTN), appeared to be the most vital indicator for facial esthetics. The horizontal sum, a variable for AP characteristics of the patient, could be a better variable when compared with the overjet.
  
  
  CONCLUSIONS
  Addition of this newly defined parameter to the AC/IOTN improved the prognostic value from 25% to 35%.
