Investigate of central nervous system related to tooth clenching

我们的长期目标是阐明潜在的机制清醒磨牙症的特点是频繁的咬牙。在这个术语中，我们调查比较视觉反馈之间的影响脊髓和三叉神经肌肉的活动，和效果的重复和标准化的咬牙任务corticomotor兴奋性评估运动诱发电位咬肌。我们的研究结果表明，视觉反馈的影响是不同的贡献显着的控制之间的脊神经支配和三叉神经支配的肌肉，和神经可塑性的皮质运动控制的咬肌诱发的重复咬牙任务。

The long term aim of our project is to elucidate mechanisms potentially underlying awake bruxism which is characterized by frequent tooth-clenching. In this term, we investigated comparison of the influence of visual feedback between spinal and trigeminal muscle activity, and the effect of repeated and standardized tooth clenching tasks on corticomotor excitability as assessed by motor evoked potentials in the masseter muscle. Our findings suggest that influence of visual feedback was different contributes significantly to the control of both between spinally-innervated and trigeminally-innervated muscles, and neuroplasticity in the corticomotor control of the masseter muscles evoked by repeated tooth-clenching tasks.
