title: Association between normative and self-perceived orthodontic treatment need among 12- to 15-year-old students in Shiraz, Iran.
abstract: Self-perception of dental attractiveness is an important factor affecting orthodontic treatment need. The purpose of this study was to investigate the association between normative and self-perceived orthodontic treatment need and to evaluate the influence of gender and socioeconomic background such as family size, parental education and father's employment. The subjects were 900 male and female junior high school students (450 males, 450 females) aged 12-15 years, from four districts in the city of Shiraz, Iran. The participants were asked to complete a questionnaire and then underwent a dental examination. Normative treatment need was assessed clinically using the Dental Aesthetic Index (DAI) according to the World Health Organization guidelines. Statistical analysis was undertaken using t- and chi-squared tests. There was no statistically significant correlation between DAI scores and demographics. The results showed a significant correlation between DAI scores and a subject's awareness of malocclusion and their satisfaction with dental appearance. There were no differences between genders concerning the questionnaire data. The results suggest that the DAI score might reflect a self-perceived need for orthodontic treatment.
