背景。尽管已有报道称年龄相关的变化导致吞咽反射减慢和神经肌肉控制系统下降，但有关齿状老年人吞咽功能的报道却很少。本研究的目的是阐明衰老对拥有20颗以上牙齿的80岁以上健康有齿老年人吞咽的主要影响。方法。有齿老年人（12名男性，7名女性，平均年龄：81.2岁）和有齿青年参与者（9名男性，5名女性，平均年龄：26.8岁）作为对照组自愿参加。参与者报告没有与吞咽困难、神经损伤或退行性疾病相关的临床症状，并被要求吞咽 10 毫升硫酸钡溶液 (10% w/v) 3 次。使用数字减影血管造影系统以每秒 30 帧的速度在 35 毫米电影胶片上记录功能性吞咽。获得了坐姿参与者的口腔、咽部和喉部的荧光摄影的侧面图像。使用电影放映机进行视觉图像分析以进行定性和定量评估。结果。在三项试验中，没有参与者表现出愿望。零碎吞咽的发生和频率。有齿状老年人的液体过早流失、口腔和咽部残留物以及喉部渗透率显着高于有齿状年轻参与者 (p < .05)。与有齿的年轻参与者相比，有齿老年人的口腔通过时间、咽部延迟时间和咽部通过时间显着延长（p < .01）。结论。即使是健康的齿状老年人，生理吞咽功能也会恶化。这种恶化可能主要是由于衰老对吞咽的影响造成的。
Background. Although age-related changes resulting in slowing of the swallowing reflex and a decline in the neuromuscular control system have been reported, there have been few reports on swallowing function in dentate elderly persons. The purpose of this study was to clarify the primary influence of aging on swallowing in healthy dentate elderly persons older than 80 years who have more than 20 teeth.Methods. Dentate elderly persons (12 male. 7 female: mean age: 81.2 years) and dentate young participants (9 male, 5 female, mean age: 26.8 years) as a control group participated voluntarily. Participants reported no clinical symptoms relating to dysphagia, neurologic impairments, or degenerative diseases, and were asked to swallow 10 nil of barium sulfate solution (10% w/v) three times. Functional swallowing was recorded on 35 mm cinefilm at 30 frames per second with a digital subtraction angiography system. Lateral images of cinefluorography of seated participants' mouth, pharynx, and larynx were obtained. Visual image analysis for qualitative and quantitative evaluation was made with a cine projector.Results. No participants exhibited aspiration during three trials. Occurrence and frequencies of piecemeal deglutition. premature loss of liquid, oral and pharyngeal residues, and laryngeal penetration were significantly greater in dentate elderly persons (p < .05) than in the dentate young participants. Oral transit time, pharyngeal delay time, and pharyngeal transit time in dentate elderly persons were prolonged significantly compared with those in dentate young participants (p < .01).Conclusion. Physiological swallowing functions deteriorate even in healthy dentate elderly persons. This deterioration may be explained primarily by the influence of aging on swallowing.
