Abstract An endodontic operating and sealing or obturating method and apparatus for performing the various steps of said method are disclosed. Means for preparing a root canal for filling are disclosed which include instruments for cleaning out the root canal and preparing the interior of the canal so that it includes a series of staged steps which grow progressively larger from the apical end of the tooth to the crown. Unique finishing instruments are provided with a cross-sectional configuration such that they will provide the progressively larger steps. Also disclosed is a method and apparatus for sealing the root canal thus prepared, which includes provision of the gutta percha cones of particular configuration adapted to substantially conform to the internal stepped configuration within the root canal. Also disclosed is a combination cone which in itself is composed of a series of cones having progressively increasing diameters so as to be capable of sealing a plurality of steps in the canal. Improved means for inserting the cones into the root canal and assuring complete sealing thereof are also provided.
A substantially compressible gutta percha endodontic sealing cone for use in root canals, comprising an elongate substantially cylindrical body with first and second ends; said body having a plurality of offset shoulders at spaced intervals along its length to form progressively larger segments from said first to said second ends; and a handle projecting from said second end and being removably disposed centrally of said body and extending from a point adjacent said first end of said body.

A substantially compressible gutta percha endodontic sealing cone for use in root canals, comprising an apical finishing member having a base end and an opposed end with an offset reduced diameter projection thereon; a plurality of secondary finishing members of substantially equal dimensions arranged in series from the base end of said apical finishing member; and a handle removably disposed centrally of said finishing members; said handle extending from said apical finishing member through said secondary finishing members and projecting from the last said secondary finishing member.
