Literature is not yet conclusive about orthodontic treatment s psychosocial benefits. The aim of this study was to assess oral health-related quality of life (OHQoL) and self-perceived aesthetics in brazilian adolescents who was under orthodontic treatment during two years of prospective evaluation. The sample consisted of 318 subjects, 12 to 15 years of age; 92 of these had sought and started orthodontic treatment in an university (ortho group) and the other 226 were not treated adolescents: 124 had sought orthodontic treatment at the same university but did not started, once they were waiting a vacant in the wait list to initiate the treatment (waiting group), and 102 were from a public school right next door to the university clinic and had never undergone or sought orthodontic treatment (school group). OHQoL was assessed with the Brazilian version of the short form of the Oral Health Impact Profile (OHIP-14), malocclusion severity and aesthetic impairment with the IOTN index, socioechonomic status with the Brazilian Economic Classification Criteria , and oral health with the DMTF Index. All subjects completed three distinct intervals of interviews: first interview before treatment (T1), one year after the placement of the fixed appliance for ortho group and one year after the first interview for school and waiting groups (T2) and two years after the placement of the fixed appliance for ortho group and two years after the first interview for school and waiting groups. Orthodontic treatment reduced OHRQoL scores from 10.4, to 9.2 and 1.6, among first, second and third interviews (p<0.001), and also produced a significant reduction in self-perceived aesthetics (p<0.001), and in malocclusion severity (p<0.001). Patients who have finished the treatment had significant better results in all scores than the ones who received treatment for two years but still were wearing braces. Adolescents from waiting group reported worse scores in OHRQoL, wich rised from 10.8 to 12.0 between first and third interviews (p<0.001). Self-perceived aesthetics scores also worsened (p<0.001) during the evaluation period in this group. On the other hand, adolescents from school group did not had alterations in any of the evaluated indexes, including OHRQoL (p=0.34) and self-perceived aesthetics (p=0.09). In patients from not treated groups (waiting and school groups), malocclusion severity did not change during the two years, as well as DMTF did not worsened in any of the three groups. Orthodontic treatment in brazilian adolescents resulted in significant better OHRQoL and self-perceived aesthetics.
