In addition, it sought to assess the concordance between adolescents\u2019 self-perception of the Aesthetic Component of the IOTN (AC-IOTN) with the evaluations made by orthodontic professionals.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>MATERIAL AND METHODS:<\/jats:title>\n                    <jats:p>A two-stage stratified cluster sampling method was used to select 248 high school students aged 11\u201314. Clinical examinations were conducted by specialist orthodontists. DAI, AC-IOTN, and DHC-IOTN were measured based on the students\u2019 occlusal morphology. Students also made self-assessments using the AC-IOTN.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS:<\/jats:title>\n                    <jats:p>In terms of DHC-IOTN, 9.7% of students had severe cases that definitely needed treatment. The DAI assessment identified 5.2% with severe malocclusion and 4% with handicapping malocclusion. Using the AC-IOTN, the students assessed 4.8% of cases as severe, compared with 8.5% according to orthodontists. A comparative analysis of the results of the modified DAI and the DHC-IOTN, using Chi-squared test demonstrated highly significant differences between the two indices.<\/jats:p>\n
