Retrieval of Separated Root Canal Instruments: A Case Series
Abstract presentation type
Case report
INTRODUCTION
Instrument separation during endodontic treatment is a significant complication that compromises root canal disinfection and shaping. Such obstructions can harbor bacteria, potentially affecting long-term periapical healing. Successful management is essential to regain access to the full working length. Various clinical techniques and specialized equipment are utilized for fragment retrieval. This case series presents four distinct methods for fractured instrument removal and discusses their clinical management.
CASE DESCRIPTION
Four clinical cases involving fractured intra-canal instruments were evaluated:
Case 1: A 43-year-old male with a fragment in tooth 16; retrieval was achieved using the BTR Pen system (Cerkamed, Poland).
Case 2: A 47-year-old female with a fragment in tooth 15; removal was performed via a custom wire loop technique.
Case 3: A 64-year-old female with a fragment in tooth 38, retrieved through ultrasonic activation (Satelec, France).
Case 4: A 60-year-old female with a fragment in tooth 16; removal involved wedging the instrument into an H-file using flowable composite (custom tube and glue technique).Following retrieval, root canal therapy was completed in all cases.
All patients remained asymptomatic at a 1-month follow-up.

All patients remained asymptomatic at a 1-month follow-up.
DISCUSSION
Retrieval success depends on instrument localization, canal morphology, and fracture level. While ultrasonic systems and specialized kits are common, selecting a minimally invasive approach is vital to preserve root dentin and enhance prognosis.
CONCLUSION/CLINICAL SIGNIFICANCE
Mastering diverse retrieval techniques and selecting the appropriate method for specific cases provides a significant advantage in complication management, increasing the success rate of endodontic therapy.
