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.
自我感知的牙齿美观是影响正畸治疗需求的一个重要因素。本研究旨在探讨规范感知的正畸治疗需求与性别以及家庭规模、父母教育程度和父亲就业等社会经济背景之间的关系。研究对象为来自伊朗设拉子市四个区的 900 名 12-15 岁的男女初中生（男生 450 人，女生 450 人）。要求参与者填写一份问卷，然后进行口腔检查。根据世界卫生组织的指导方针，使用美观指数（DAI）对规范治疗需求进行临床评估。采用 t 检验和卡方检验进行统计学分析。DAI 评分与人口统计学数据之间无统计学显著相关性。结果表明，DAI 评分与患者对错牙合的认识以及对牙齿美观的满意度之间存在显著相关性。问卷调查数据在性别方面没有差异。结果表明，DAI 评分可能反映了自我感知的正畸治疗需求。
