ABSTRACT:
A toothbrush having an improved cleaning and abrasion efficiency, wherein the bristles are comprised of synthetic thermoplastic polymeric compositions, and contain longitudinal channels extending along the length thereof, having a depth sufficient to entrap a quantity of abrasive particles such that during brushing with a toothpaste, contact between the channel entrapped abrasive particles and the surfaces of the teeth is improved, resulting in a cleaning efficiency coefficient, CEC, above about 1.5 and, an abrasion efficiency coefficient, AEC, above about 1.5, while demonstrating suitable bristle wearability.
