Abstract
BackgroundThe aim of this study is to assess the agreement between orthodontist’s and Chinese young adult’s self-perceived aesthetics, the normative treatment need based on the Index of Orthodontic Treatment Need (IOTN), and the main factors affecting the self-perceived aesthetics.MethodsA random sample of 348 Chinese young adults (116 males and 232 females) aged 17–24 years were recruited in this study. Two orthodontists were involved in rating the cases. Orthodontic treatment need was assessed according to the Index of Orthodontic Treatment Need, including Aesthetic components and Dental Health Components (AC and DHC). Personality traits were assessed according to Eysenck Personality Questionnaire (EPQ). Cohen’s kappa test was used to assess the agreement, and spearman’s correlation coefficient was used to analyze the association among all variables.ResultsA statistically significant level of agreement was observed between young adult’s perception and orthodontist’s perception in IOTN (kappa = 0.14). A positive relationship (p < 0.001)existed between the young adult’s AC and the orthodontist’ s AC (r = 0.275), and between the young adult’ s AC and the normative need DHC (r = 0.195). The orthodontist’s AC was strongly related to the normative need (r = 0.743, p < 0.001). Association between the young adult’s AC and gender and EPQ-E were also observed.ConclusionsYoung adults tend to be less critical in assessing orthodontic treatment needs than orthodontists. The orthodontist’s AC reflecting subjective treatment need is strongly connected to the normative need. The adult’s perception of aesthetic component is affected by factors such as gender and personality traits.
Highlights
When young adults are seeking orthodontic treatment, it is appropriate for orthodontists to consider the patient’s aesthetic component, since this component may influence the communication between the patient and the orthodontist, which will in turn enable the orthodontist to assess his or her expectations

A significant positive relationship existed between the young adult and orthodontist’s Aesthetic Component (AC) scores (r = 0.275, p < 0.001), and between young adult’s AC and Dental Health Component (DHC) (r = 0.195, p < 0.001)
Summary
The aim of this study is to assess the agreement between orthodontist’s and Chinese young adult’s self-perceived aesthetics, the normative treatment need based on the Index of Orthodontic Treatment Need (IOTN), and the main factors affecting the self-perceived aesthetics. The subjective orthodontic treatment need of Chinese natives is high [1]. Apart from the dental health needs, it is necessary to take subjective aesthetic into consideration as well [2]. Among the Chinese young adults, the common motivation for orthodontic treatment is associated with the desire for improvement in appearance [3]. It is suggested that dental esthetics may be important in individual oral-health attitudes and behaviors [5,6,7]. When young adults are seeking orthodontic treatment, it is appropriate for orthodontists to consider the patient’s aesthetic component, since this component may influence the communication between the patient and the orthodontist, which will in turn enable the orthodontist to assess his or her expectations. The self-perceptions of young adults are important indicators when deciding to undertake treatment, and this might complement
