Since the decision to seek orthodontic treatment is frequently the result of concerns about appearance, assessment of need for treatment should include an impartial evaluation of dental-facial appearance. While some of the standardized techniques for assessing malocclusion have included a consideration of esthetic impairment, they tend to confound this with functional impairment. The purpose of this study was to develop a valid and reliable index that provides relatively objective judgments of dental-facial attractiveness. The subjects in this study were eighth- and ninth-grade children seeking orthodontic treatment and their siblings, and eighth- and ninth-grade children not seeking treatment and their siblings. Photographs of the children were rated for dental-facial attractiveness by lay and dental judges. Children were also assessed for severity of malocclusion by means of the Treatment Priority index. Children seeking treatment were perceived as significantly less attractive than children not seeking treatment. Dental judges rated children seeking treatment as more attractive than did nondental judges. Intraclass reliability coefficients were moderate to high.

A previous report describes the reliability and validity of a scale designed to assess perceptions of dental-facial attractiveness, independent of occlusal function. The purpose of the present study was to assess the consistency of judgments of dental-facial attractiveness (DFA) for sex and race differences in photographed children. Using a five-pont DFA scale, twelve college freshmen (three black females, three black males, three white females, three white males) rated ninety-six photographs of the mouths and jaws of 13- to 14-year-old children (twenty-four black females, twenty-four black males, twenty-four white females, twenty-four white males). No significant mean differences were found between the black and white photographed or between the female and male children photographed. However, means were significantly different for DFA judgments by race and sex of the raters. Black raters judged all photographs to be more attractive than did white raters, and female raters judged all photographs to be more attractive than did male raters. Correlational data are presented describing consistency of perception within rater groups and photographed groups of children.
