Abstract: A gutta-percha remover suitable for removing a gutta-percha and having flexibility with good compliancy to curvature of a root canal and a superior removing capability for forming a sufficient gap bet the gutta-percha and the root canal wall is provided. The gutta-percha remover includes a shaft, a tapered working portion connected to the shaft, and one, two, or more screw-shaped grooves formed in the working portion. The cross-sections of a base end and a tip of the working portion are such that the tip of the working portion is greater in rate of the area of each cross-section to a corresponding circle circumscribing the cross-section.

Abstract: A gutta-percha remover suitable for removing gutta-percha and having flexibility with good compliancy to curvature of a root canal and superior removing capability for forming a sufficient gap between the gutta-percha and the root canal wall is provided. A gutta-percha remover (10) includes a shaft (12), a tapered working portion (13) connected to the shaft (12), and one, two, or more screw-shaped grooves (14) formed in the working portion, wherein as to cross sections (13a, 13b) of a base end and a tip of the working portion, the tip of the working portion (13) is greater in rate of the area of each cross-section to corresponding circle (13a3, 13b3) circumscribing said each cross section.
