Abstract

INTRODUCTION

This trial aimed to longitudinally evaluate the effect of the treatment of transverse maxillary deficiency using rapid palatal expansion (RPE) on self-perceived oral health-related quality of life (OHRQOL) in children.

METHODS

Eighty participants aged 8-10 years with transverse maxillary deficiency and bilateral posterior crossbite were randomly assigned to 2 groups (n = 40 each): a group treated with RPE using hyrax-type appliances and a nontreated control group. OHRQOL was assessed by using the Child Perceptions Questionnaire for 8-10-year-olds at 4 times: before RPE, during RPE (T), at the end of RPE (T), and 1 month after the appliance removal (T). Generalized mixed models were used for data analysis (α = 0.05).

RESULTS

Both groups exhibited similar demographic characteristics and OHRQOL scores at baseline. All participants completed the study. RPE had a time-dependent effect on OHRQOL. At T and T, this therapy is expected to increase the overall OHRQOL scores by 1.17 times (ie, ∼17% increase; T 95% confidence interval [CI], 1.08-1.26; T 95% CI, 1.09-1.27; P = 0.001). In contrast, the overall OHRQOL scores at T are expected to be 0.28 times the baseline scores (ie, ∼72% reduction; T 95% CI, 0.26-0.31; P = 0.001). All individual domains of the OHRQOL evidenced a positive impact of treatment at T (P = 0.001). Only the oral symptoms and social well-being domains showed a significantly negative impact of the treatment at T and T.

CONCLUSIONS

Correction of the transverse maxillary deficiency by RPE in children aged 8-10 years improves OHRQOL. There is a temporary worsening of OHRQOL during the treatment of this condition using RPE.

摘要

引言

本试验旨在纵向评估使用腭扩展快速（RPE）治疗横向上颌发育不全对 8-10 岁儿童自我感知口腔健康相关生活质量（OHRQOL）的影响。

方法

80 名 8-10 岁患有横向上颌发育不全和双侧后牙反牙合的参与者被随机分为 2 组（每组 40 名）：一组使用 hyrax 型器具接受 RPE 治疗，一组为未治疗对照组。在 4 个时间点使用儿童感知问卷（8-10 岁）评估 OHRQOL：RPE 前、RPE 期间（T）、RPE 结束时（T）和矫治器去除后 1 个月（T）。使用广义混合模型进行数据分析（α=0.05）。

结果

两组在基线时均具有相似的人口统计学特征和 OHRQOL 评分。所有参与者均完成了研究。RPE 对 OHRQOL 有时间依赖性影响。在 T 和 T 时，这种治疗预计会使整体 OHRQOL 评分增加 1.17 倍（即，增加约 17%；T95%置信区间[CI]，1.08-1.26；T95%CI，1.09-1.27；P=0.001）。相比之下，T 时的整体 OHRQOL 评分预计将是基线评分的 0.28 倍（即，减少约 72%；T95%CI，0.26-0.31；P=0.001）。OHRQOL 的所有个体域均表现出治疗的积极影响T（P=0.001）。只有口腔症状和社会幸福感这两个领域在 T 和 T 时表现出治疗的显著负面影响。
