To investigate the changes in oral health-related quality of life (OHRQoL) before, during, and after orthodontic treatment, determine the relationship with the original treatment need and evaluate the influence of self-esteem (SE).
OHRQoL questionnaires were used in an ongoing observational prospective cohort study at baseline (T0), 1 year after start (T1), and 1 month after the end of active orthodontic treatment (T2). Participants were 11-16-year-old at baseline and 215 complete cases were obtained from a total of 498. OHRQoL was scored by using the Child Perception Questionnaire (CPQ11-14), SE was assessed by the Dutch adaptation of the Harter's Self-Perception Profile for Adolescents and treatment need was defined by the Index of Orthodontic Treatment Need (IOTN). The Oral Aesthetic Subjective Impact Scale (OASIS) was included to score perceived treatment need. Data were analyzed with Spearman correlation, Mann-Whitney U-test and linear models for longitudinal data.
A significant decrease in IOTN and in OASIS was noted from T0-T1-T2 (P < 0.0001). CPQ results show a decrease from T0 to T2, from T1 to T2 and an increase from T0 to T1 (P < 0.0001). This was valid for the overall CPQ scores and its subdomains except for emotional well-being (EW), which decreases from T0-T1-T2. A correlation was found between baseline SE and the change of total CPQ scores between T0 and T2, also for EW (r = 0.325 and r = 0.354).
OHRQoL ameliorates after orthodontic treatment. High baseline SE works as a protective factor for OHRQoL.
研究正畸治疗前、治疗期间及治疗后的口腔健康相关生活质量（OHRQoL）变化，确定其与初始治疗需求的关系，并评估自尊（SE）的影响。
在一项正在进行的观察性前瞻性队列研究中，于基线期（T0）、开始治疗1年后（T1）以及正畸治疗结束后1个月（T2）使用OHRQoL问卷。参与者在基线期年龄为11 - 16岁，从总共498例中获得215例完整病例。使用儿童感知问卷（CPQ11 - 14）对OHRQoL进行评分，通过荷兰版青少年哈特自我感知量表评估SE，并通过正畸治疗需求指数（IOTN）定义治疗需求。纳入口腔美学主观影响量表（OASIS）以对感知到的治疗需求进行评分。使用Spearman相关性分析、Mann - Whitney U检验和纵向数据线性模型对数据进行分析。
从T0到T1再到T2，IOTN和OASIS均显著降低（P < 0.0001）。CPQ结果显示从T0到T2、从T1到T2呈下降趋势，从T0到T1呈上升趋势（P < 0.0001）。这适用于CPQ总分及其子领域，但情绪健康（EW）除外，EW从T0到T1再到T2呈下降趋势。还发现基线SE与T0和T2之间CPQ总分的变化存在相关性，EW也是如此（r = 0.325和r = 0.354）。
正畸治疗后OHRQoL有所改善。高基线SE对OHRQoL起到保护作用。
