To assess the impact of fixed appliance therapy on the quality of life of a cohort of Brazilian adolescents.
The treatment group was composed of individuals who started orthodontic treatment. The control group was composed of individuals not selected for immediate treatment. Adolescents answered the Brazilian short form of the Child Perceptions Questionnaire (CPQ). Higher scores indicate a greater negative impact on quality of life. Adolescents in the treatment group completed four sets of interviews: prior to appliances' bonding (T1), 1 month (T2), 6 months (T3) and 12 months (T4) after appliances' placement. Adolescents in the control group were assigned to a comparable schedule. Statistics included inter-group comparisons, Friedman and Wilcoxon tests, and mixed-effects models.
In the treatment group, the functional limitation score was higher at T1 (p = 0.004) and T2 (p = 0.007) compared to T4. The emotional well-being score was higher at T1 compared to T2 (p < 0.001), T3 (p < 0.001) and T4 (p < 0.001). The overall CPQ score was higher at T1 compared to T2 (p = 0.005), T3 (p < 0.001) and T4 (p < 0.001). The overall CPQ score was also higher at T2 compared to T3 (p = 0.001). No significant change was found in the control group. In the mixed-effects models, the interaction between group (treatment) and time was significant for functional limitations (p < 0.001), emotional well-being (p < 0.001), social well-being (p = 0.004) and the overall CPQ score (p < 0.001).
Quality of life improved among adolescents undergoing orthodontic treatment. Orthodontists should inform patients what they might expect regarding the physical and the psychosocial repercussions of appliance therapy.
评估固定矫治器治疗对巴西青少年生活质量的影响。
治疗组由开始正畸治疗的个体组成。对照组由未选择立即治疗的个体组成。青少年回答了巴西儿童感知问卷（CPQ）的简短形式。得分越高表示对生活质量的负面影响越大。治疗组的青少年完成了四组访谈：在矫治器粘接前（T1）、1 个月（T2）、6 个月（T3）和 12 个月（T4）后。对照组的青少年被分配到类似的时间安排。统计分析包括组间比较、Friedman 和 Wilcoxon 检验以及混合效应模型。
在治疗组中，T1（p=0.004）和 T2（p=0.007）时功能障碍评分高于 T4。T1 时情绪健康评分高于 T2（p<0.001）、T3（p<0.001）和 T4（p<0.001）。T1 时总体 CPQ 评分高于 T2（p=0.005）、T3（p<0.001）和 T4（p<0.001）。T2 时总体 CPQ 评分高于 T3（p=0.001）。对照组未发现显著变化。在混合效应模型中，组间（治疗）和时间的交互作用对功能障碍（p<0.001）、情绪健康（p<0.001）、社会健康（p=0.004）和总体 CPQ 评分（p<0.001）具有统计学意义。
接受正畸治疗的青少年生活质量有所提高。正畸医生应告知患者他们可能会预料到治疗器具治疗的身体和心理社会影响。
