ENDODONTISCHES INSTRUMENT |
摘要 |
An improved endodontic dental instrument is provided for extirpating and/or obturating a root canal. The instrument has two or more flutes defining tissue removing edges wherein the flutes are formed unequal in size, shape and/or spacing about the periphery of the instrument shaft so as to provide an instrument having a degree of asymmetry. Lands are provided adjacent the tissue removing edges and at least a portion of the lands are recessed from the periphery to reduce frictional loads on the instrument during extirpating and obturating procedures (Fig.1a). <IMAGE> |
