Ultrasonic Removal of Broken Instruments in Root Canals
International Endodontic Journal, 1986Summary. A method to remove broken instruments in root canals was developed employing a new ultrasonic device for root canal treatment. The results, using extracted teeth, showed that broken instruments locked tightly in round root canals were more difficult to remove compared with those in irregularly shaped root canals. This method was applied in 39

The Influence of Endodontic Broken Stainless Steel Instruments on the Urinary Levels of Iron
Biological Trace Element Research, 2014Previous studies on the endodontic broken stainless steel instruments have mainly focused on retrieval of specimens. However, the systemic consequences of the retained separated instruments need an investigation. The current study aimed to evaluate the correlation between broken stainless steel instruments inside the root canal space and the urinary ...

Broken Instrument Removal—Two Cases
Journal of Endodontics, 2000This paper reports two clinical aids for the removal of broken instruments in root canals using a combination of hand instrumentation and ultrasonic devices. This technique is based on two phases: hand instrumentation with stainless-steel K-file instruments for bypassing the fragments, and K-files mounted on an ultrasonic handpiece for loosening and ...

A new approach for the retrieval of broken instruments
Journal of Endodontics, 1999The purpose of this article is to present a modified ultrasonic spreader and a new technique that are used for the retrieval of solid obstructions that can not be bypassed by conventional methods. The technique advocated and the instruments proposed are described. A clinical case is discussed to show the possibilities and limitations of both instrument
