Abstract

During endodontic practice, a practitioner may encounter iatrogenic errors that are unpleasant and affect the outcome. One common iatrogenic error that can occur during dental treatments is instrument separation. This issue can significantly hinder the disinfection of the root canal system. The clinician must evaluate the treatment alternatives of orthograde or surgical retrieval the separated instrument or bypassing it and sealing the fragment within the root canal space. One method for managing a separated instrument is the loop technique. This case series reports four cases of successful retrieval of separated instruments using the loop technique, which is a reliable, effective, and safe method for file retrieval. It also provides a rapid review of the relevant literature. © 2025 Dental Research Journal.
