OBJECTIVE
To investigate the effect of splint therapy on masseter muscle and blood flow in patients with bruxism using ultrasonography (USG).
METHODS
Twenty female patients with bruxism receiving splint treatment were studied. Masseter thickness and elasticity were assessed using gray-scale USG and shear-wave elastography (kPa) at rest and maximum clenching. Blood flow parameters of external carotid artery (ECA), maxillary, facial, mental artery were examined using Doppler USG before and after splint application.
RESULTS
Thickness and elasticity of masseter muscle was statistically significantly decreased at rest after splint therapy (p < 0.05). Significant difference was determined only in some parameters of ECA and maxillary artery in Doppler USG before and after splint (p < 0.05); there was no difference for facial and mental artery (p > 0.05).
CONCLUSION
Thickness and elasticity of masseter muscle were significantly decreased after splint therapy. USG can measure muscle activity and blood flow in bruxism patients.
目的
采用超声检查（USG）研究夹板疗法对磨牙症患者咬肌及血流的影响。
方法
对20名接受夹板治疗的女性磨牙症患者进行研究。在静息及最大紧咬时，使用灰阶超声检查和剪切波弹性成像（kPa）评估咬肌厚度及弹性。在佩戴夹板前后，使用多普勒超声检查颈外动脉（ECA）、上颌动脉、面动脉、颏下动脉的血流参数。
结果
夹板治疗后，静息时咬肌厚度及弹性在统计学上显著降低（p < 0.05）。夹板治疗前后多普勒超声检查中，仅ECA和上颌动脉的一些参数存在显著差异（p < 0.05）；面动脉和颏下动脉无差异（p > 0.05）。
结论
夹板治疗后咬肌厚度及弹性显著降低。超声检查可测量磨牙症患者的肌肉活动及血流情况。
