Abstract

The invention concerns a diamond-coated endodontic access bur which is coated at least 10 mm along the shaft. This significant amount of diamond coating along the shaft permits the bur to be used both for dentin removal and finishing the slope and sidewalls of the tooth's pulp chamber. The bur sphere, also diamond coated, has a diameter of 0.5 to 1.0 mm, approximately.
