A STUDY OF THE FUNCTION OF SWALLOWING IN VARIOUS ORAL ENVIRONMENTS

对咀嚼能力的评价进行了研究。但他们中的大多数人关心的是将食物碾碎成食物的能力。在牙科领域，有关吞咽功能的文章很少，据说吞咽时会出现吞咽呼吸暂停，与呼吸相协调。从这一角度出发，本研究探讨了不同口腔环境下吞咽功能的变化。在本研究中，我们通过表面电信号分析了舌骨上肌、颞前肌等与吞咽功能相关的肌肉。此外，还记录了吞咽过程中的同步呼吸图。结果显示，戴义齿的老年人与不戴义齿的老年人的协调模式不同。垂直高度和腭板引起了协调格局的改变。但我们必须进一步调查患者适应新环境的能力。

The evaluation of masticatory ability has been investigated. But the majority of them are concerned with the ability crushing food to piecies. There are few articles about the function of swallowing in the field of dentistry.It is said that there is deglutition apnea upon swallowing which is coordinated with respiration. From this point of view this study investigates the function of swallowing in various oral environment.In this report we analyze different muscles related in the function of swallowing such as suprahyoid muscles and anterior tempolar muscle by surface electrograms. In addition, a simultaneous respirograms were recorded during swallowing. A test was conducted to clarify the difference in vertical height and the size of palatal plate.As a result, the patterns of coordination in aged people with denture were different from those without denture. Vertical height and palatal plate caused change of the pattern of coordination. But we have to investigate the patient's ability to adapt to new environment furthermore.
