Original Abstract Submitted
a power toothbrush device () including a brush head member () having a set of bristles (); a body portion () coupled with the brush head member; and a drivetrain assembly (). the drivetrain assembly includes an actuator () configured to generate periodic linear movement and a drivetrain shaft () configured to transmit the generated periodic linear movement to the brush head member. the set of bristles are configured to be driven in a first direction (tm) at an amplitude equal to or greater than 0.25 mm and less than 3 mm and a frequency equal to or greater than 0.25 hz and less than 520 hz in the first direction. the drivetrain shaft is further configured to periodically rotate the set of bristles in a second direction (sm) about a central axis of the power toothbrush device.
