ABSTRACT:
An obturator for use in filling an endodontically prepared root canal in a tooth formed as an elongated body having a handle portion and a shaft, the handle portion being configured for grasping by a practitioner whereby the shaft may be inserted into a root canal, the shaft tapering from the handle to the shaft distal end, the shaft having an exterior surface having a generally linear groove therein extending from near the handle to the shaft distal end, or at least adjacent the shaft distal end, the groove providing: (a) a channel for flow of excess filler material as the shaft is positioned into a prepared root canal; (b) increased flexibility of the shaft, and (c) a passageway that will accept a slender, tapered metallic retrieval tool, such as a typical endodontic file, to assist in the removal of the shaft from a root canal.
