Abstract

Introduction: Dental Aesthetic Index (DAI) is an orthodontic index on the basis of aesthetic standards defined by the community. The main goal of this study was to evaluate the orthodontic treatment needs of 14-18 year-old students in Shiraz using DAI. Materials & Methods: Using random cluster sampling process in this descriptive-analytical study, 1818 students (965 boys and 853 girls) who were 14-18 years old without any orthodontic treatments were selected. The information was gathered by the method recommended by World Health Organization (WHO) and using a questionnaire that contained demographic characteristics. The data were analyzed by chi-square and T-tests. Results: In 12.3 % of students, treatment was highly needed and in 8.1% of them treatment was mandatory. There was a significant difference in DAI score between girls (27.2) and boys (25.9) (P<0.001). About half (48.3%) of samples did not need orthodontic treatment and almost one fifth of them (21%) had severe malocclusion who needed orthodontic treatment. Conclusion: Orthodontic treatment need in adolescent students of Shiraz was comparable to Spanish adolescents, more than Caucasians of Australia and Nigerian people but less than Japanese adolescents. Key words: Orthodontic treatment need, DAI (Dental Aesthetic Index), Shiraz.
