  • Objective: To assess the impact of wearing a fixed orthodontic appliance on oral health-related quality of life (OHRQoL) among Brazilian children.

    Design: Cross-sectional study.

    Setting: The Department of Paediatric Dentistry and Orthodontics at Federal University of Minas Gerais, Belo Horizonte, Brazil.

    Participants: Sample of 579 children aged 11�14 years. The children were divided into two groups: wearing (n?=?160) and not wearing (n?=?419) a fixed orthodontic appliance.

    Methods: A clinical examination was performed by a single examiner to determine whether or not a fixed orthodontic appliance was worn, the presence of a malocclusion using the Dental Aesthetic Index (DAI) and cavitated carious lesions. The impact of wearing a fixed orthodontic appliance on OHRQoL was measured using the short form of the Brazilian version of the Child Perceptions Questionnaire (CPQ11�14). Data analysis involved descriptive statistics, Mann�Whitney test and univariate/multiple logistic regression.

    Results: The total CPQ11�14 score revealed a more frequent impact among children who wore a fixed orthodontic appliance than those who did not (P?=?0·002). Similar findings were observed for the FL (P?=?0·005), EWB (P?=?0·006) and SWB (P?=?0·003) subscales. There was no statistically significant difference between the two groups regarding the score on the OS subscale (P?=?0·124). While females were 1·76 times more likely to have a worse OHRQoL than males, the use of a fixed orthodontic appliance was also significantly associated with a greater chance (OR?=?1·60; CI?=?1·11�2·33) of impacting OHRQoL when both variables were inserted together in the regression model.

    Conclusion: Children wearing a fixed orthodontic appliance had significantly worse OHRQoL compared with a control group with no malocclusion and not wearing a fixed appliance.
