Development of diagnosis support system for mastication-swallowing function

本科研助学金(C)(19592231)对咀嚼吞咽功能诊断支持系统的开发进行了研究，通过计算咀嚼笔划数直至米饼最初吞咽的次数来考察义齿治疗对咀嚼吞咽功能的影响，为开发新的咀嚼功能评价方法奠定基础。80岁以上受试者的TMD症状和体征并不常见。因此，老年人的咀嚼功能与TMD之间没有关系。由于压电式脉冲传感器(PPT)可以检测周围脉搏波，PPT已经被用来简单地记录喉部上下运动。基于这一事实，我们开发了用于评估吞咽功能的原型。牙科的远程医疗也进行了尝试。

Development of diagnosis support system for mastication-swallowing function was studied by this Grant-in-Aid for Scientific Research (C) (19592231).For developing new method of the evaluation in mastication function, we investigated or the effects of prosthetic treatment by counting the number of chewing strokes until initial swallow of rice crackers. TMD signs and symptoms of 80-year old subjects were not so common. Therefore, there is no relation between mastication function and TMD in elderly subjects.Since a Piezoelectric Pulse Transducer (PPT) detects peripheral pulse-waves, the PPT has already been used to simply record the laryngeal upward-downward movements. Based on this fact, we developed the prototype to evaluate the swallowing function. The telemedicine in the dentistry was also tried.
