The management of separated endodontic instruments using a customized syringe and loop technique: A case series

Abstract

The separation of the nickel-titanium (NiTi) rotary files is seen occasionally due to improper use and lack of technique, which results in improper cleaning and shaping of the root canals, compromising the treatment outcome. Various techniques have been introduced to either bypass or retrieve the separated instrument. The present case series highlighted a low-cost and straightforward alternative to retrieve the separated NiTi rotary instruments using a customized syringe and loop technique with the assistance of a dental operating microscope. Three cases of fractured instruments in different root canals were addressed, with the customized syringe and loop technique being used to retrieve the instruments successfully. This supports the use of a convenient, reliable, and cost-effective approach to managing fractured endodontic instruments without costly equipment or specific retrieval kits.
