Materials and Methods: This is an observational cross-sectional descriptive study. A total of 129 female students with age ranges between 14 and 17 years old were randomly selected from Mashhad (Iran) high schools and were asked to fi ll out an OHRQOL questionnaire included in four parts: Oral symptoms, functional limitations, emotional well-being and social well-being. Each participant was clinically examined to assess her malocclusion according to the index of complexity, outcome and need (ICON) and fi nally the data were entered to SPSS 11.5 and the relation between these two variables was assessed with Pearson correlation test. P < 0.05 was considered as statistically signifi cant.
Results: There was statistically signifi cant correlation between ICON scores and quality of life (P = 0.0176). Being separately assessed, among four parts of the questionnaire, only emotional
well-being was signifi cantly correlated with the ICON score (P < 0.05).
Conclusion: Malocclusions play a vital role in OHRQOL. However, in female adolescents among four parts of OHRQOL, emotional well-being had signifi cant relationship with malocclusions.
