A STUDY OF THE FUNCTION OF SWALLOWING OF ELDERLY PEOPLE

本研究旨在探讨戴全口义齿的老年人吞咽功能，通过测量吞咽唾液时的呼吸电图，并通过表面电图记录与吞咽功能相关的肌肉活动，如舌骨上肌和颞前肌。本研究以实验的方式探讨有无假牙对牙齿的影响。所有受试者在呼气时均识别出吞咽期间的吞咽呼吸暂停。2..戴义齿后吞咽呼吸暂停的持续时间较戴义齿后明显延长，提示戴义齿对吞咽呼吸模式和吞咽功能有影响，但口腔环境中的许多因素与吞咽呼吸暂停的持续时间有关，需要进一步研究患者的适应能力。

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.
