Assessment of Orthodontic Treatment Need and Oral Health-Related Quality of Life in Asthmatic Children Aged 11 to 14 Years Old: A Cross-Sectional Study.

Unlabelled: This study investigated the need for orthodontic treatment in asthmatic children aged 11 to 14 years and how the treatment affected their oral health-related quality of life (OHRQoL).

Materials And Methods: This cross-sectional study was conducted at the dental clinic of the University of Salamanca in 2020-2022. The study selected a consecutive sample of 140 children with asthma (52.1% girls; 47.9% boys). This study used the Orthodontic Treatment Needs Index (OTN) to analyze the need for orthodontic treatment and the Children's Perception Questionnaire (CPQ11-14) to assess OHRQoL.

Results: Sex and age did not significantly influence the need for orthodontic treatment, although age may be considered influential for OHRQoL concerning oral symptoms ( < 0.01), functional limitations ( < 0.05), and total score on the CPQ questionnaire ( < 0.05): the younger the age, the greater the effect of the need for orthodontic treatment on OHRQoL. The social well-being of the patients was much more significantly impacted by the need for orthodontic treatment (15.7 ± 1.91) than by oral symptoms (7.64 ± 1.39), which were the least impacted. In all parts of the CPQ questionnaire and in the patients' total scores, we observed significant agreement ( < 0.01) that treatment influenced OHRQoL.

Conclusion: An inverse relationship exists between the severity of the treatment needed and OHRQoL.
