由于目前还没有一个明显的指标来评价患者的刷牙动作，因此牙科专业人员很难客观地评价患者的刷牙技术。本研究的目的是定量评估刷牙时牙刷和手臂关节的运动。刷牙运动，由牙科医生进行了15秒，被捕获使用的运动捕捉系统，连续计算物体的运动相对于地板的三维坐标。牙科医生在他们的右上磨牙和左上磨牙的颊侧和腭侧进行刷牙。计算牙刷运动的频率和功率谱以及肩、肘、腕关节的角度，并进行统计分析。牙刷运动的频率在左侧（颊和腭区）高于右侧。各刷牙区域内关节角度频率无显著差异。刷牙时手肘屈曲角度的功率谱的个体间和个体内变化小于任何其他角度。这项研究定量地证实了牙科医生在刷牙过程中具有独特的节奏。刷牙时手臂各关节同步运动，通过关节协调运动控制刷牙动作。手肘通过稳定运动产生个体的频率。肩和腕控制着手的运动，手肘则在刷牙时产生周期性的节奏。
It is very difficult for dental professionals to objectively assess tooth brushing skill of patients, because an obvious index to assess the brushing motion of patients has not been established. The purpose of this study was to quantitatively evaluate toothbrush and arm-joint motion during tooth brushing. Tooth brushing motion, performed by dental hygienists for 15 s, was captured using a motion-capture system that continuously calculates the three-dimensional coordinates of object’s motion relative to the floor. The dental hygienists performed the tooth brushing on the buccal and palatal sides of their right and left upper molars. The frequencies and power spectra of toothbrush motion and joint angles of the shoulder, elbow, and wrist were calculated and analyzed statistically. The frequency of toothbrush motion was higher on the left side (both buccal and palatal areas) than on the right side. There were no significant differences among joint angle frequencies within each brushing area. The inter- and intra-individual variations of the power spectrum of the elbow flexion angle when brushing were smaller than for any of the other angles. This study quantitatively confirmed that dental hygienists have individual distinctive rhythms during tooth brushing. All arm joints moved synchronously during brushing, and tooth brushing motion was controlled by coordinated movement of the joints. The elbow generated an individual’s frequency through a stabilizing movement. The shoulder and wrist control the hand motion, and the elbow generates the cyclic rhythm during tooth brushing.
