ABSTRACT:
An endodontic instrument for preparing the root canal which is suitable for being mounted on an endodontic contra-angle and with a conventional handle for manual use. The instrument is constituted by a series of broaches in which the working part is short with respect to the overall length. The instrument, by pivoting with its end portion in the apical part of the canal, which is prepared beforehand by the files, always works at the apex and prepares, in each instance, a small part of the canal, advancing progressively from the coronal inlet to the apex.
