The prospect of Ni-Ti rotary instruments in root canal therapy especially small bending and molar application is quite bright, because of its good flexible property. But instruments separation and postoperative root fracture are still common problems in clinical practice. In recent years, many scholars have discussed the stress distribution of Ni-Ti rotary instrument and the mechanical characters of tooth root during preparation. This re-view focused on the clinical research recently.
