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.
Claims13
An instrument for cleaning a canal of a tooth after debriding of the canal with a file, comprising:
- a handle;
- a shank collinear with the handle, wherein the shank tapers over a length from a proximal end to a tip at a distal end of the shank, and wherein the shank is sized so that the distal end can reach an apical third of the canal;
- a plurality of raised projections on the shank for a portion of the length of the shank sized to reach the apical third of the canal, wherein the projections are composed of the same polymeric composition as the shank, and wherein the handle, shank and projections consist of a one piece polymeric composition.
