Broken endodontic instrument removal

The primary pain points for dentists in removing broken endodontic instruments include limited visibility, accessibility within narrow and curved root canals and the risk of further fracturing the instrument or damaging the tooth structure.¹ These challenges are critical because a retained broken instrument can lead to persistent infection, failure of the root canal treatment and potential tooth loss.² Proper by-pass or removal is essential to prevent these complications and ensure the success of the endodontic therapy.³ High-magnification and coaxial effective illumination provided by the use of the operative microscope and specialized tools are typically required to navigate these difficulties effectively.⁴ The challenge of this clinical situation without microscope is shown in the picture, which demonstrate that is impossible to visualize the broken fragment without help from microscope from naked eyes perspective.
