摘要
A brushhead assembly (10) for a power toothbrush (1), which includes a bristle plate (12) and a set of bristles (14) mounted to the bristle plate (12). The set of bristles (14) is characterized such that some or all of the bristles have a dipole whip motion during operation at a selected drive frequency, including arrangements where the bristles in a first portion (32) have a different motion than the bristles at a at least a second portion (34) of the brushhead assembly (10).
