Self-esteem (SE) is suggested to influence the relationship between orthodontic treatment need and oral health-related quality of life (OHRQoL), but evidence lacks. The aim of the present study was to investigate SE in the relationship between subjective orthodontic need and OHRQoL in children.
This cross-sectional study was embedded in the Generation R Study, a multi-ethnic population-based cohort. In total, 3796 10-year old children participated in the present study. OHRQoL, measured with the Child Oral Health Impact Profile-ortho, and subjective orthodontic need were assessed within parental questionnaires. SE was measured with a modified version of the Harter's self-perception profile rated by the children. The role of SE in the association between SOT and OHRQoL was evaluated with linear regression models. Furthermore, the difference in this association between children with high and low SE was investigated.
Higher subjective orthodontic need was associated with lower OHRQoL scores (borderline: β [95% CI] = -0.55 [-0.77, -0.33]; definite: -1.65 [-1.87, -1.54]). Children with lower SE scores showed a stronger relationship between borderline and definite subjective orthodontic need with OHRQoL (β [95% CI] = -0.56 [-0.81, -0.31] respectively -1.68 [-1.94, -1.42]) than children with higher SE scores did (β [95% CI] = -0.51 [-0.97, -0.04] respectively -1.43 [-1.90, -0.95]).
The relationship between subjective orthodontic need and OHRQoL is not based on the SE of children. However, SE modifies the relationship between subjective orthodontic need and OHRQoL. Work still needs to be done to find an explanation for the effect modification by SE in the relationship between subjective health perceptions and OHRQoL.
自尊（SE）被认为会影响正畸治疗需求与口腔健康相关生活质量（OHRQoL）之间的关系，但缺乏相关证据。本研究的目的是调查儿童主观正畸需求与OHRQoL关系中的自尊情况。
这项横断面研究纳入了以多民族人群为基础的队列研究“Generation R研究”。共有3796名10岁儿童参与了本研究。通过父母问卷评估OHRQoL（采用儿童口腔健康影响量表正畸版进行测量）和主观正畸需求。儿童通过对修改版的哈特自我认知量表进行评分来测量自尊。采用线性回归模型评估自尊在主观正畸治疗需求（SOT）与OHRQoL关联中的作用。此外，还研究了高自尊和低自尊儿童在这种关联上的差异。
较高的主观正畸需求与较低的OHRQoL得分相关（临界：β[95%CI]=-0.55[-0.77，-0.33]；确定：-1.65[-1.87，-1.54]）。自尊得分较低的儿童在临界和确定的主观正畸需求与OHRQoL之间的关系（β[95%CI]分别为-0.56[-0.81，-0.31]和-1.68[-1.94，-1.42]）比自尊得分较高的儿童（β[95%CI]分别为-0.51[-0.97，-0.04]和-1.43[-1.90，-0.95]）更强。
主观正畸需求与OHRQoL之间的关系并非基于儿童的自尊。然而，自尊会改变主观正畸需求与OHRQoL之间的关系。仍需开展工作以找到自尊在主观健康认知与OHRQoL关系中产生效应修正的解释。
