To clarify the oral environment, we evaluated the usefulness and clinical applicability of a new apparatus developed for the simple and rapid quantification of oral bacteria.
Professional oral health care can reduce the number of oral bacteria and days of fever and inhibit the development of pneumonia. A novel detection apparatus was developed by applying the dielectrophoretic impedance measurement method.
First, to determine the accuracy of this apparatus, employing standard samples of Escherichia coli. Next, to evaluate the oral environment, samples were taken from the tongue in elderly (mean age: 86.6 years) in nursing home.
In the first study, a good correlation was observed between the two methods (R = 0.999). In the second study, there were significant correlations between measurement values obtained using this apparatus and those obtained by the culture method (R = 0.852), as well as those obtained by the FM method (R = 0.885).
Our data showed that this rapid oral bacterial detection apparatus is effective in evaluating the oral hygiene to prevent pneumonia in the elderly.
为了阐明口腔环境，我们评估了一种新仪器的有用性和临床适用性，该仪器旨在简单、快速定量口腔细菌。
专业的口腔保健可以减少口腔细菌数量和发热天数，抑制肺炎的发展。一种新的检测仪器通过应用介电泳阻抗测量方法开发。
首先，通过使用大肠杆菌的标准样本来确定该仪器的准确性。接下来，为了评估口腔环境，从养老院的老年人口腔（平均年龄：86.6 岁）中采集样本。
在第一项研究中，两种方法之间观察到良好的相关性（R = 0.999）。在第二项研究中，该仪器的测量值与培养法（R = 0.852）和 FM 法（R = 0.885）获得的值之间存在显著相关性。
我们的数据表明，这种快速口腔细菌检测仪器在评估预防老年人肺炎的口腔卫生方面是有效的。
