| 20100203471 | DENTAL FILLING MATERIAL - A dental filling material includes a head; a distal tip opposite the head, wherein the distal tip is designed to be first inserted into a tooth root canal, a body tapered from the head to the distal tip, with a diameter decreasing from the head to the distal tip, one or more work length marks formed on the body. The work length marks indicate a work length. One or more taper marks are formed on the head in order to indicate a degree of taper. The work length marks are formed on a portion of the body, the portion of the body extending to the distal tip with a predetermined interval from the taper marks. Both the taper marks and the work length marks have the same color, which corresponds to a value of the diameter, in order to identify the diameter. | 08-12-2010 |
