Abstract:
An endodontic instrument system adapted for anatomically removing and for anatomically cleaning essentially all pulp material from an operative middle portion and an apical root portion of an operative root canal in a tooth, the endodontic instrument system comprising:a first endodontic instrument means for anatomically removing and anatomically cleaning essentially all pulp material from the operative middle portion without significantly removing pulp material from the apical root portion, said first endodontic instrument means comprising:operative middle portion instrument means for flexibly conforming to the anatomical shape of the operative middle portion so as to effect removal and cleaning of pulp material as the first instrument means is operatively moved, said operative middle portion instrument means having an abrading portion with a length and flexibility which causes the removal of pulp material from essentially all of the operative middle portion of the root canal; andend means for grasping and operatively moving in an abrasive action the operative middle portion instrument means while bending and flexing the operative middle portion instrument means;a second endodontic instrument means for improving access into the apical root portion after the pulp material has been essentially removed from the operative middle portion by the first endodontic instrument means; anda third endodontic instrument means for removing and cleaning essentially all remaining pulp material from the apical root portion after access into the apical root portion has been improved by the second endodontic instrument means.
