A STUDY OF THE FUNCTION OF SWALLOWING OF ELDERLY PEOPLE

研究老年人佩戴全口义齿后吞咽功能的变化。我们测量了吞咽唾液时的呼吸图，并通过表面电图记录了舌骨上肌和颞前肌等与吞咽功能相关的肌肉活动。进行了一项测试，以澄清是否有假牙的影响。结果是1。所有受试者在呼气时均可识别出吞咽过程中的吞咽呼吸暂停。2 . .不戴假牙时的吸气时间比不戴假牙时的更长。结果表明，假牙对吞咽过程中的呼吸方式和吞咽功能有影响。但口腔环境的许多条件与吞咽时吞咽呼吸暂停的持续时间有关，我们还需要进一步调查患者的适应能力。

It is a study to investigate the function of swallowing of elderly people who wear complete dentures.We measured respirograms during swallowing saliva , and muscle activities related in the function of swallowing such as suprahyoid muscles and anterior tempolar muscle were recorded by surface electrograms. A test was conducted to clarify the influence with dentures or not.The results were that 1. Deglutition apnea during swallowing was recognized by all subjects when they breathe out. 2.. The duration of breathe in when they wore no no dentures was longer than it when they wore dentures.It was suggested that the respiration pattern and deglutition during swallowing were influenced by wearing dentures.But many condition of oral environment are related with the duration of deglutition apnea upon swallowing , we have to investigate the patient's ability to adapt to them furthermore.
