Dental Microscope-Assisted and Indirect Ultrasonic Technique for Retrieval of Separated Endodontic Instruments: A Case Report
Article Sidebar
Main Article Content
Abstract
Endodontic procedures pose significant challenges during both the diagnostic and treatment phases of root canal therapy (RCT). Instrument separation or fracture is a potential complication during canal shaping, especially when utilizing rotary nickel-titanium (NiTi) files.
The dental microscope is a required magnification tool in United States endodontic training programs and is considered an essential component of the endodontist’s clinical toolkit. The improved visual information and resolution provided by the microscope’s lighting and adjustable magnification allow clinicians to address complex challenges in deep, narrow canal regions and to manage obstructions that may compromise the success of root canal treatment.
The decision to bypass or retrieve a separated instrument should be informed by established clinical principles. The selection of appropriate tools and techniques for file retrieval must be consistent with these principles to ensure precise and effective treatment.
This case report outlines a systematic approach to file retrieval during complex root canal treatment, guided by established clinical principles, continuous magnification, and the use of Sonic Steel probes designed for the indirect ultrasonic file retrieval technique. The clinical effectiveness of the indirect ultrasonic technique, in combination with ultrasound, is demonstrated in this case report.
