Abstract

Purpose: The aim of the present study was to record the electromyographic (EMG) activity of the mentalis muscle (Ment) during various jaw functions in healthy young subjects.Methods: Twelve healthy males were enrolled for the study. A portable EMG recording device was used to record the EMG activity from the Ment, anterior belly of the digastric muscle (Dig), and the masseter (Mm) muscles. The EMG activities of these muscles were recorded during maximal voluntary clenching (MVC), maximal voluntary jaw opening (MVO), and the masticatory process. The EMG activity of Ment was compared with the EMG activities of Dig and Mm during various jaw functions.Results: (1) The EMG activities of Ment and Dig were significantly greater during MVO than during MVC (P<0.05). A strong correlation was found between the activities of Ment and Mm during MVO (r=0.739, P<0.01), and between those of Ment and Dig during MVC (r=0.664, P<0.05). (2) It was observed that during mastication of peanuts, Ment showed synchronous activity with that of Dig and reciprocal activity with that of Mm.Conclusion: These results indicate that Ment acts in coordination with the actions of Dig and Mm during various jaw functions.

健康青年口腔周围肌肌电图活动在颌骨功能中的特征

目的:本研究的目的是记录健康青年颏肌在各种颚功能过程中的肌电活动。方法:选取12名健康男性进行研究。使用便携式肌电记录仪记录Ment肌、二腹肌前腹肌(Dig)和咬肌(Mm)肌的肌电活动。在最大自主握紧(MVC)、最大自主张开下巴(MVO)和咀嚼过程中记录这些肌肉的肌电图活动。比较了Ment与Dig、Mm在不同颌功能时的肌电活动。结果:(1)MVO时Ment和Dig的肌电活动显著高于MVC时(P<0.05)。MVO期间Ment与Mm活性呈极显著相关(r=0.739, P<0.01)， MVC期间Ment与Dig活性呈极显著相关(r=0.664, P<0.05)。(2)在花生咀嚼过程中，Ment与Dig的活性同步，与Mm的活性相互作用。结论:在花生咀嚼过程中，Ment与Dig和Mm的作用相互协调。
