ABSTRACT:
A sequence of canal instruments for performing an endodontic operating protocol uses a sequence of several instruments, for example, three such instruments with three cutting blades. The instruments have a progressive conicity, for example, 6%, 4% and 2%, and each instrument has an identical progressive pitch. The pitch further increases progressively from instrument to instrument as a function of the conicity of each instrument.
