This study looked at the aesthetic and dental health components of the index of orthodontic treatment need in relation to peer assessment of dental health and aesthetic need (panel of 74 dentists). The dental health component had a Spearmans correlation coefficient of +0.64 and the aesthetic component +0.86 when compared with the mean subjective opinion of 74 dentists. It has been proposed to have three categories for both the dental health and aesthetic components in accordance with consensus opinion. The panel of 74 examiners were more likely to regard aesthetics as a greater need for treatment than dental health.
