The purpose of this research was to develop the new system that evaluate the relevance of dental factor for swallowing. In the previous year, we found that occlusal support and tongue movement were closely related to swallowing function. This year, we improved the system that could evaluate laryngeal movement simultaneously. In the elderly, there were so many denture-wearers, owing to the loss of their own teeth with aging. Although wearing and removing dentures gave considerable change in their oral cavity, especially, in complete denture-wearers, there was little study about both swallowing and dentures. So we selected wearing and removing dentures as a dental factor to evaluate relevance to swallowing. Subjects were experimented under four conditions ; with upper and lower dentures, without lower denture, without upper denture, without both dentures.Total swallowing duration and the latent period until laryngeal elevation were significantly prolonged without upper or lower denture, and without both dentures. Their prolongation was due to the prolongation of the preparatory and oral stages. Especially, removing upper denture disturbed the stable tongue movement on swallowing, and would affects the oral-pharyngeal coordination of swallowing, and exacerbates the depression of swallowing functions with aging. These results suggested the importance of wearing dentures as a new approach for dysphagia rehabilitation from the dentistry.

本研究的目的是开发评估牙齿因素与吞咽相关性的新系统。去年，我们发现咬合支撑和舌头运动与吞咽功能密切相关。今年，我们改进了可以同时评估喉部运动的系统。在老年人中，有很多戴假牙的人，因为随着年龄的增长，自己的牙齿脱落了。尽管佩戴和摘除义齿给口腔带来了相当大的变化，尤其是全口义齿佩戴者，但关于吞咽和义齿的研究却很少。因此，我们选择佩戴和摘除假牙作为牙齿因素来评估与吞咽的相关性。受试者在四种条件下进行实验；带上下义齿、不带下义齿、不带上义齿、不带双托义齿。不带上下义齿、不带双托义齿时，总吞咽持续时间和喉部抬高潜伏期显着延长。它们的延长是由于准备阶段和口试阶段的延长。尤其是摘除上颌义齿，会扰乱吞咽时舌头的稳定运动，影响吞咽的口咽协调性，并会随着年龄的增长而加剧吞咽功能的衰退。这些结果表明佩戴假牙作为牙科吞咽困难康复新方法的重要性。
