Abstract
A dental tool for generating a relatively smooth surface on tooth enamel comprises an elongated shank with an operative end and an end adapted to engage a chuck of a dental handpiece. Any cross-section of the operative end perpendicular to the shank's longitudinal axis is circular with a diameter of less than 0.140 inch. Adjacent, continuous annular grooves extend around the operative end, each groove being defined by a pair of inwardly sloping side surfaces intersecting with each other at least about 0.010 inch from the shank's longitudinal axis and forming an included angle of 60.degree. to 150.degree. between the side surfaces. An abrasive material, such as diamond grit, having a particle size of less than 0.006 inch covers at least a portion of each surface.
