The aim of this study was to assess both, the prevalence of malocclusions among patients received in the Dental Surgery Unitat Yalgado Ouédraogo Teaching Hospital and their care needs according to IOTN index. Materials and Methods: It is a prospective, cross-cutting diagnostic study of malocclusions at Yalgado Ouédraogo Teaching Hospital (CHUYO), conducted from January 1 to December 31, 2016. The examiner with an examination tray records on the 12-to 16-year-old patients' medical recorded, the variables based on the polychromatic pictures series, the IOTN rule, and the dental health component table. Results: On the whole, 81 patients were included, with 60.5% of girls and 39.5% of boys. 16-and 12-year-old patients were dominant. The average age was 14.05 years old. Various types of malocclusions were encountered. The need for orthodontic care was 56.8%. For 14 patients, 17.28%, their aesthetic component score is higher than the assessment made by the orthodontist. Conclusion: Aesthetics was an important factor in the need for orthodontic care. The aesthetic deficit entails a psychological impact that should be taken into account in the assessment of care needs.How to cite this paper:

Correlation of orthodontic treatment motivation and the level of treatment needs based on the index of orthodontic treatment need (IOTN) of orthodontic patients

“…The level of need for treatment was assessed using the dental health component (DHC) in the index of orthodontic treatment need (IOTN). The results of this study was also supported by previous research conducted by Ouedraogo et al 22 , which demonstrated that 91.4% of adolescent patients visiting orthodontic clinics required orthodontic treatment. Also, another study by Nobile et al 23 showed that 59.5% of the respondents, children and adolescents, belong to the grade 4 and 5.23 level of treatment needs.…”
