Management Of Separated Instruments In Endodontics

This book provides a comprehensive guide to understanding preventing and managing fractured instruments during endodontic procedures. Instrument separation is a common procedural complication in root canal therapy potentially affecting treatment prognosis and clinician confidence. The book begins with an overview of the types of instruments prone to fracture (e.g. stainless steel files nickel-titanium rotary instruments) and the primary causes such as cyclic fatigue torsional stress and improper usage.Key chapters explore diagnostic methods including radiographic and cone-beam computed tomography (CBCT) evaluation for accurate localization of the fragment. The book outlines treatment decision-making based on factors such as the location of the fragment (coronal middle or apical third) canal anatomy and the presence of periapical pathology.A range of retrieval techniques are detailed including:-Ultrasonics-Bypassing techniques-Instrument retrieval kits (e.g. Masserann Kit IRS system)-Microtube and loop techniques-Surgical approaches when non-surgical methods failPrevention strategies are emphasized.
