Abstract
An instrument for cleaning canals during endodontic procedures is presented. The instrument is formed in one piece from a stiff polymeric material. The instrument features a handle, a measuring shaft, and a tapering shank with raised polymeric projections along its length. The present invention is designed without the use of bristles that conventional brushes contain. The raised polymeric projections include fins that may be oriented parallel to or transverse to the axis of the instrument to provide multidirectional cleaning capability. The instrument is stiff enough to penetrate a canal and mechanically scrub and scrape canal surfaces, but flexible enough to negotiate the curves of the canal.
