BACKGROUND
This study aims to compare the relationship between skeletal and dental outcomes of rapid maxillary expansion (RME) treatment on cone beam computed tomography (CBCT) images between pre-pubertal peak (pre-peak) and post-pubertal peak (post-peak) patients. The null hypothesis was that there was no difference in the outcomes of RME treatment between the groups.
METHODS
Thirty-two patients who underwent RME treatment were classified according to midpalatal suture maturation levels and then divided into two groups as pre-peak and post-peak. Skeletal and dental measurements were performed on the CBCT images at T0 (pre-treatment stage) and at T1 (post-treatment stage). Paired sample t test was used to evaluate normally distributed data and P < 0.05 was taken as the significance level.
RESULTS
There were significant differences between T0 and T1 within the groups, but the changes between the pre-peak and post-peak patient groups were not statistically significant.
CONCLUSION
Non-significant changes were found between the two groups, and the null hypothesis was excepted.
背景
本研究旨在比较在锥形束 CT（CBCT）图像上，快速上颌扩张（RME）治疗在青春期前高峰期（pre-peak）和青春期后高峰期（post-peak）患者之间的骨骼和牙齿结果的关系。零假设是两组之间 RME 治疗结果没有差异。
方法
根据中隔缝成熟度水平，将 32 名接受 RME 治疗的患者进行分类，然后分为 pre-peak 和 post-peak 两组。在 T0（治疗前阶段）和 T1（治疗后阶段）时，在 CBCT 图像上进行骨骼和牙齿测量。使用配对样本 t 检验评估正态分布数据，P<0.05 为显著性水平。
结果
组内 T0 与 T1 之间存在显著差异，但 pre-peak 和 post-peak 患者组之间的变化无统计学意义。
结论
两组之间未发现显著变化，因此拒绝零假设。
