    • The combination of a power toothbrush and an oral fluid, in which the oral fluid has the characteristic of changing viscosity, depending upon the action of a workpiece element portion, such as a flexible membrane, of the power toothbrush. The power toothbrush has two operating conditions. In one condition, the membrane moves toward and away from the teeth at a speed such that the fluid is liquid and flows easily to and around the teeth, including the interproximal regions. In the second condition, the membrane is moved at a significantly higher speed, in response to which the viscosity of the fluid increases substantially, having a shear rate at least as great as necessary to remove biofilm from the teeth.
    • 根据动力牙刷的工件元件部分(例如柔性膜)的作用,动力牙刷和口腔液体的组合,其中口腔液体具有改变粘度的特征。 动力牙刷有两个操作条件。 在一个条件下,膜以一定的速度朝向和远离牙齿移动,使得流体是液体的并且容易地流到牙齿周围并且包括邻接区域。 在第二个条件下,以显着更高的速度移动膜,响应于此,流体的粘度基本上增加,其剪切速率至少要从牙齿去除生物膜所需的那么大。
