ABSTRACT:
The present invention provides a dental tool which operates as a reamer, while reducing the danger of removing excessive tooth material when boring out the tooth canal. The dental tool includes a first holder end portion designed to be receiveable in a dental tool holder, such that the dental tool holder can rotate the dental tool; a second reaming end portion having a polygonal cross-section and cutting edges tapering longitudinally endwardly to a minimum effective cutting diameter plane, or a point, from a plane of maximum effective cutting diameter, and optimally also having reverse cutting surfaces tapering longitudinally in the opposite direction to an inner plane of reduced effective cutting diameter; and a shank portion extending between the two end portions. The plurality of reamer cutting edges extend axially, and are designed for reaming out a bore into a tooth canal of a patient upon rotation of the tool. The shank portion has an effective cross-section diameter along its length which is smaller than the diameter at the plane of maximum effective cutting diameter or at the plane of reduced effective cutting diameter of the reaming end portion. Most preferably, the shank tapers inwardly towards the first holder end portion, such that the plane of smallest diameter of the shank is located adjacent the first holder end portion.
