ABSTRACT:
A root canal filler assembly including a single use obturator and a multiple use elongate inserter tool is disclosed. The oburator includes a metallic core and a plasticizable coating, preferably formed of gutta percha. One end of the metallic core extends beyond the plasticizable coating to support a connector assembly. The multiple use inserter tool is removably connectable to the oburator to insert, remove, adjust, and reposition the obturator in a root canal. The inserter tool includes at one end a connector assembly which engages the obturator and at the other end a handle to facilitate manipulation of the assembly by the dentist. The elongate inserter tool may be reused as required, both to remove or reposition a previously inserted obturator and to insert additional obturators in other root canals.
A method of filling and sealing a root canal employing the disclosed root canal filler assembly is also provided.
