Abstract
A method of accessing a pulp chamber of a tooth without puncturing the furcation of the tooth includes providing an endodontic instrument having an elongated shaft with an upper end and a lower end, a stop fixed to the shaft at a distance between 6-8 mm from the lower end, and a cutting head located along the shaft adjacent the lower end thereof, whereby the cutting head has a cutting surface. The method includes abutting the cutting head against a crown of the tooth, rotating the endodontic instrument while applying a force through the cutting head onto the crown of the tooth for cutting through the tooth to the pulp chamber and advancing the cutting head toward the pulp chamber until the stop contacts the crown of the tooth.
