Instrument separation during root canal treatment is a procedural complication that can compromise disinfection, complicate treatment planning, and increase clinician stress. Successful management requires accurate diagnosis, understanding of canal anatomy, case selection, and mastery of contemporary retrieval and bypass techniques. This workshop provides a clinically oriented, evidence-based roadmap for preventing, assessing, and managing separated instruments. Participants will review the mechanical causes of file fracture, risk factors related to metallurgy and canal morphology, and the role of magnification and cone-beam computed tomography in decision-making. Step-by-step protocols for ultrasonic retrieval, microtube techniques, and bypass strategies will be demonstrated, with emphasis on safety, dentin preservation, and prognosis.

Course Topics
- By the end of this workshop, participants will be able to:
- • Identify the mechanical and anatomical factors that contribute to instrument separation.
- • Recognize cases in which retrieval, bypass, or retention of the fragment is indicated.
- • Apply CBCT and magnification to improve visualization and treatment planning.
- • Describe step-by-step protocols for ultrasonic and microtube retrieval techniques.
- • Perform safe dentin troughing while minimizing the risk of perforation or weakening of the root.
- • Evaluate the prognosis of teeth with separated instruments based on current evidence.
- • Communicate complications and treatment options to patients with clarity and confidence.
- • Implement preventive strategies to reduce the incidence of file fracture in daily practice.
