ABSTRACT:
An endodontic instrument has a comfortable grip especially for use for a long time of period. A handle of the endodontic instrument includes a cylindrical stem, opposite end portions, and plural brims radially extending from the circumferential surface of the stem in a plate shape juxtaposed in the axial direction of the stem with a predetermined space. When an operator grips the handle of the endodontic instrument, the operator's fingers can readily control the handle through contacts to the brims while the brims engage the bulges of the fingers adequately. The brim preferably has recesses to provide the identification of the instrument's orientation in the finger and also can preferably be made of a resilient material to make the contacts softer to provide better blood flow in finger tips and providing less finger tip stress.
