Abstract An endodontic or root canal sealing system and apparatus for practicing the system which includes an instrument for first placing a sealing or cementing substance onto the walls of the primary root canal as well as the auxiliary canals communicating therewith. The system also includes the utilization of gutta percha cones or ''''plugs'''' and an instrument for inserting said plugs into the canal following application of the sealing substance. The system also includes the utilization of an instrument either electrical, manual, or ultrasonic to heat, condense and/or pack the gutta percha cones or ''''plugs'''' into the main root canal and the auxiliary canals to thereby insure complete filling of a canal system. The system also includes the use of ultrasonically activated tips to place filling material into the cavity preparations or access openings in the crown of the tooth.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
108 words
An endodontic system for chemically and mechanically sealing the main and auxiliary passages of a root canal system, comprisinG; A. inserting an elongate instrument carrying a chemical sealing compound on one end thereof into said main passage; B. activating said instrument and forcing the chemical sealing compound against the walls of said main passage and into said auxiliary passages and against the walls thereof whereby said compound chemically seals said passages; C. inserting at least one compressible sealing plug into said main passage; D. condensing and compacting said plug and forcing the material of said plug into said auxiliary passages and against the walls of said main passage.
Claim 2
Dependent Claim
108 words
An endodontic system for chemically and mechanically sealing the main and auxiliary passages of a root canal system, comprisinG; A. inserting an elongate instrument carrying a chemical sealing compound on one end thereof into said main passage; B. activating said instrument and forcing the chemical sealing compound against the walls of said main passage and into said auxiliary passages and against the walls thereof whereby said compound chemically seals said passages; C. inserting at least one compressible sealing plug into said main passage; D. condensing and compacting said plug and forcing the material of said plug into said auxiliary passages and against the walls of said main passage.
Claim 3
Dependent Claim
15 words
The system of claim 1 wherein said plug is condensed and compacted by ultrasonic means.
Claim 4
Dependent Claim
33 words
The system of claim 1 wherein said instrument carrying said chemical sealing compound is rotated to force said compound against the walls of said main passage and said auxiliary passages by centrifugal force.
Claim 5
Dependent Claim
40 words
The system of claim 1 wherein said instrument carrying said chemical compound is activated by a motor creating supersonic vibrations to force said compound in a lateral direction against the walls of said main passage and into said auxiliary passages.
Claim 6
Dependent Claim
26 words
The system of claim 1 wherein A. additional compressible plugs are inserted, condensed, and compacted until the material thereof reaches the coronal area of the tooth.
