摘要： A kit of endodontic instruments which are adapted for use in performing root canal therapy, and wherein the instruments in the kit have increasing diameters and differing tapers. The instruments are designed to be used sequentially in root canal therapy, and the difference of the tapers serves to prevent the whole working length of the instruments from being engaged with the wall of the tapered canal being formed, to thereby reduce the frictional loading of the instruments and the risk of breakage.
