Endodontic instrument having a chisel tip |
| abstract |
An endotontic instrument (100) is provided for use in performing root canal procedures and comprises an elongate working portion (106) and a chisel tip portion (150). The chisel tip (150) has plural facets which form a chisel edge (154) additional tissue removing edges (255, 257) that improves the effectiveness of the instrument in extirpating and enlarging the root canal. The working portion (106) has a non-uniform taper which accelerates from a proximal end (107) of the instrument to a distal end (108) forming a region of enhanced compliance (264) adjacent the tip (150). |
