Oral health is closely related to mental and physical health. Generally speaking, the elderly use a denture. It is essential for the elderly with a denture to adequately clean a denture to keep oral and physical condition healthy. To measure force exerted by a denture brush, 4 strain gauges were attached to a handle of a denture brush and a measurement tool for brushing force was calibrated. A measurement tool for quantitatively detecting the finger movement was used to evaluate finger movement. A major advantage of this magnetic sensor is that it enables the degree of finger opening and the incoordination of finger-thumb oppositions to be analyzed without being affected by involuntary movement. The subjects were instructed to tap as rapidly as possible while moving their fingers as far as they could. Power spectrum calculated from the movement-distance waveforms was available to evaluate finger movement. The main frequency in power spectrum might be a index for the ability of cleaning teeth and dentures. The main frequency was smaller in subject with dirty oral cavity and dentures than in a subject with clean oral cavity and dentures. The results suggested that a caregiver should clean oral cavity and dentures in a case of a small main frequency.

口腔健康与心理和身体健康密切相关。一般来说，老年人都使用假牙。对于戴假牙的老年人来说，充分清洁假牙对于保持口腔和身体健康至关重要。为了测量假牙刷施加的力，将4个应变计安装到假牙刷的手柄上，并对刷牙力的测量工具进行校准。使用定量检测手指运动的测量工具来评估手指运动。这种磁传感器的一个主要优点是，它可以分析手指张开的程度和手指与拇指相对的不协调性，而不受不自觉运动的影响。受试者被要求尽可能快地敲击，同时尽可能地移动手指。根据移动距离波形计算出的功率谱可用于评估手指移动。功率谱中的主频率可能是清洁牙齿和假牙能力的指标。口腔不洁和假牙的受试者的主频率比口腔清洁和假牙的受试者的主频率要小。结果表明，护理人员在主要频率较小的情况下应清洁口腔和假牙。
