      One hundred root canals in the mesial roots of extracted mandibular molars were prepared with either the Giromatic or by serial preparation. The roots were sectioned at 1, 3, and 5 mm from the apex, stained, and examined under low power of the light microscope. The serial preparation was significantly more effective than the Giromatic preparation in removing tissue debris from the root canal.
