title: An evaluation of a new mechanized endodontic device: the Endolift.
abstract: Four methods of canal preparation are tested: hand instrumentation with preflaring and step back, Giromatic, Union Broach Endo Angle, and the Kerr Endolift. The preparations are analyzed with plastic blocks and extracted human teeth. Hand instrumentation with preflaring and step-back is superior to and safer than the mechanized endodontic devices. With proper care and technique, some mechanized endodontic devices can produce adequate canal preparations.
