ABSTRACT:
A dental drill having an elongate drill body tapered to a conical tip. The drill body has a plurality of substantially identical barbs projecting outwardly from the drill body and arranged helically about the drill body. Each barb has an outer peripheral profile resembling a parabola in shape extending generally toward the tip of the drill body. Each barb has a flat surface contiguous with the flat surface of an adjacent barb at a point of juncture with the drill body. The barb flat surfaces are disposed in a common helical path about the drill body and each has a shape resembling a parabola. The barbs have a peripheral profile also resembling a parabola. Each resembles a paraboloid in which intersections by planes parallel to the corresponding flat surface thereof and spaced axially on the drill body resemble parabolas with the axes thereof decreasing in length as the intersections are made in a direction toward the tip of the drill body.
