Study of factors affecting bolus preparation

本研究的目的是阐明老年患者备丸的影响因素。30名老年人作为受试者，他们被指示一口吃两种颜色的米饭。我们使用电视内窥镜对咽部准备丸剂的功能进行评估，并对口腔功能因素进行评估。采用多元回归分析：以唾液量、咀嚼次数、后牙合支撑数为解释变量，以备丸情况为客观变量。分析表明，唾液量与丸剂的制备有关，其他与之无关。这些结果表明，唾液分泌对老年人准备丸剂是重要的。

The purpose of this study was to clarify the factors affecting bolus preparation in the elderly. The thirty elderly are used as subjects, who were instructed to have two color rice at a mouthful. We evaluated the function of bolus preparation in pharynx, using videoendoscopy and assessed the factors of oral function. The multiple regression analysis was performed: the amount of saliva, the number of mastication and the number of posterior occulusal support were adopted as explanatory variable and the status of bolus preparation were adopted as objective variable. The analysis showed the amount of saliva was related to the bolus preparation and the others were not. These results indicated that saliva secretion is important to prepare the bolus for the elderly.
