Abstract: A depth limiting bur is provided. The depth limiting bur can include a cutting head with a diameter of at least two millimeters, a depth cut limiter with a convex surface, and a rod.

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.

Abstract: A conical dental bur for endodontic procedures, including exploration, deep troughing, enlargement of orifices, and canal navigation is presented. The bur of the present invention has a narrow, conical bur head with cutting members along its length. The head of the bur of the present invention is mounted to a shank that tapers to the bur head, allowing microscopic observations of endodontic procedures. The bur may be manufactured of tungsten carbide, diamond, ceramics, or other materials. Burs according to the present invention of various shapes and sizes, suited for particular procedures, may be packaged together in kits. Methods of using the burs in endodontic procedures are also disclosed.
