In order to develop an objective evaluating method for the swallowing function, the tongue movements using a general-purpose ultra-sound diagnostic equipment and swallowing sounds using a heart sound microphone in deglutition of ten normal healthy dentate and two edentulous patients were observed and analyzed. The tongue movement and swallowing sounds recorded on the recording paper was analyzed by plotting of five inflection points (T1, T2, T3, T4 and T5) of the movement curve and two beginning points of swallowing sounds (S1 and S2) using a digitizer.There were no significant differences in all parameter in each measurement. It was confirmed that all the data had repeatability.There was significant correlation between T4 and S1, T4 and S2 statistically (p<0.001). S1 was always ahead of T4 statistically (p<0.001). In the relationship between T4 and S1 in three edentulous patients, the time lag of T4 and S1 was extended in case of with denture in comparison with without denture. When an edentulous patient is not using his denture, swallowing is speculated to be difficult because the mandible has to be risen upper more than necessity.From this investigation, it is suggested that our evaluating method could be useful for diagnosis of swallowing function.

为了建立一种客观的吞咽功能评价方法，对10例正常健康有牙者和2例无牙者在吞咽过程中使用通用超声诊断仪观察舌部运动和使用心音传声器观察吞咽声音进行了分析。用数字化仪绘制舌运动曲线的5个拐点（T1、T2、T3、T4、T5）和吞咽音的2个起始点（S1、S2），对记录在录音纸上的舌运动和吞咽音进行分析。各项指标均无显著性差异。所有数据均具有可重复性。T4与S1、T4与S2的相关性有统计学意义（p<0.001）。S1总优于T4 （p<0.001）。在3例无牙患者T4和S1的关系中，有义齿的患者T4和S1的滞后时间比没有义齿的患者延长。当无牙患者不使用假牙时，吞咽被认为是困难的，因为下颌骨必须比必要时更高。本研究提示本方法可用于吞咽功能的诊断。
