Revisiting Braiding Technique Under Magnification to Enhance Predictability of Instrument retrieval - A Clinical Case Series

Abstract

Instrument fracture during root canal therapy is a significant complication that can disrupt proper cleaning and shaping, potentially impacting the tooth's long-term prognosis. This article discusses the occurrence, challenges, and retrieval techniques for fractured endodontic instruments. The incidence of intracanal instrument fractures ranges from 0.25% to 6%, with contributing factors including flexural fatigue, torsional fatigue, and manufacturing defects. Traditional retrieval methods, such as ultrasonics and loop devices, often face limitations, particularly with longer fragments or without magnification. This article introduces the dual-file retrieval technique under magnification as a more predictable and less technique-sensitive alternative. By strategically bypassing the broken instrument from multiple sides, this method ensures effective engagement and controlled removal, while minimizing dentin loss. Cases demonstrating the conventional braiding technique and the dual-file retrieval technique are presented, highlighting the advantages of modern visualization tools like dental microscopes in improving retrieval success rates. The dual-file retrieval technique enhances the reliability of endodontic treatments and contributes to better long-term outcomes for patients.
