Study on investigation about demand for dental treatment for the bed-ridden elderly

这些天，随着日本老年人的增加，卧床不起的老年人也增加了。然而，他们的真实情况仍不得而知。因此，在这项研究中，研究人员直接与患者见面，并检查口腔状况以获得数据。在此基础上，编制了调查问卷，于1998-1999年间对142名老年人进行了问卷调查，调查内容如下。剩余的牙齿数量2。缺失牙齿的数量3。在日常生活中的自立程度。口腔卫生自我保健程度等。采用BDR指标(自理能力的标准)对调查结果进行分析。男性和女性平均缺牙18颗。随着年龄的增长，剩余牙齿减少。在有牙齿的老年人中，平均剩余牙齿为13颗。66.2%的老年人上颌使用假牙，67.4%的老年人使用下颌义齿。从痴呆程度、卧床情况和BDR之间的关系来看，卧床状况不是影响口腔卫生的因素，但痴呆是影响卫生的重要因素。根据这些结果，可以根据卧床情况和BDR指示器的图形来进行牙科助理工作的数值化，也可以制定每个人的口腔护理的标准程序。

As the elderly increase these days in Japan, also the bed-ridden elderly increase. However, the real situation of them is still unknown. Therefore, in this study, investigators met patients directly and examined the condition of oral cavity to obtain data. Based on these data, questionnaire was prepared.This survey was carried out between 1998 and 1999 for the 142 elderly.Items for survey are as follows.1. Number of remaining teeth2. Number of missing teeth3. Degree of self-independence in daily life4. Degree of self care for oral hygiene etc.We analyzed the acquired results using BDR Indicator (standard for self-dependence). Average number of missing teeth was 18 in both male and female. As age increased, remaining teeth decreased. Average remaining teeth was 13 among the elderly who had teeth. 66.2% of the elderly used false teeth in the maxilla and 67.4% used false teeth in the mandible.Considering from the relation among degree of dementia, condition of bed-ridden and BDR, condition of bed-ridden was not the factor to effect on oral hygiene, but dementia was the important factor for hygiene. From these results, it would be possible to make the job for the dental assistant numerical based on the condition of bed-ridden and the figure of BDR Indicator, and also make the standard procedure of oral care for each person.
