With the advent of rotary nickel-titanium (Ni Ti) instrumentation the issue became extremely prominent. Extensive research has been conducted to understand the mechanics of instrument separation. This has led to changes in the manufacturing methods, instrument design and instrumentation protocols. Most recently, reciprocation is challenging rotary instrumentation in terms of speed and safety from fracture. Although the incidence of file breakage can be drastically decreased, it cannot yet be eliminated. No matter what instruments you are using inside the root canal system, the prevention and management of broken endodontic instruments still remains a hot topic. This lecture aims to review the most common preventive measures to avoid file breakage and to provide clinical tips and recommendations for the management of challenging broken file cases. Highly invasive, minimal invasive and non invasive broken instrument removal techniques are showcased through video case presentation series under the microscope.
