An improved appliance for use in applying filler material, such as gutta-percha or the like, to an endodontically prepared root canal of a tooth in the form of an elongated shaft (12) of material having high biological tolerance, the shaft having a handle portion (26) at the proximal end portion (40), the shaft distal end portion (42) having a surface configuration adaptable to retain filler material formed thereon and being positionable in a root canal, the shaft distal and proximal portion being severable from each other whereby the distal portion and filler material therein remain in the root canal. In the preferred arrangement the shaft distal portion surface is defined by a spiral groove (44). |
