Abstract
An endodontic instrument in accordance with the present invention includes a substantially non-cutting pilot segment, a relatively short cutting segment, and a flexible shaft segment, which can have a handle at its distal end for manual manipulation, or an adapter for attachment to a mechanical handpiece. The non-cutting pilot, the short length of the cutting segment, and the flexibility of the shaft combine to allow the instrument to be used in curved root canals without causing undue change in the natural root canal contours.
