On the basis of animal experiments, it has been hypothesized that the dynamics of food reduction are controlled by peripheral receptors. Studies on this subject in human beings are rare.
This study investigated the influence of periodontal and joint proprioceptors on mastication in human beings.
Both jaw joints and the chewing-side teeth were consecutively anesthetized in a 6-person panel by chewing wine gum. The effects on the kinematics, chewing force, and electromyographic activity were measured.
The results substantiate a positive feedback of periodontal receptors for chewing force control. A substantial influence of joint receptors on movement control could not be found.
Despite the absence of proprioception in both jaw joints and the periodontal receptors in the chewing side, the characteristics of the measured kinematic and dynamic values remained essentially unchanged.
基于动物实验，有人提出食物减少的动态过程受外周感受器控制。关于人类这一主题的研究很少。
本研究调查了牙周和关节本体感受器对人类咀嚼的影响。
在一个6人小组中，通过咀嚼酒胶依次麻醉双侧颞下颌关节和咀嚼侧牙齿。测量对运动学、咀嚼力和肌电活动的影响。
结果证实了牙周感受器对咀嚼力控制的正反馈作用。未发现关节感受器对运动控制有实质性影响。
尽管双侧颞下颌关节和咀嚼侧牙周感受器均不存在本体感觉，但所测运动学和动力学值的特征基本保持不变。
