Removal of Intracanal Separated Instrument in Right Upper Second Molar by Ultrasound Techniques under Dental Microscope: A Case Report

doi:10.13701/j.cnki.kqyxyj.2025.11.013

Abstract

Abstract: Instruments separation is one of the most easily occurred complications during root canal therapy, and is also a challenge to endodontic dentists. Here we reported a case of retrieval of the separated file within palatal canal of the right maxillary second molar by using the ultrasonic technique under microscope, and root canal therapy was completed. Ultrasonic technique under microscope is one of effective methods in retrieval of intracanal instruments separation.

Key words: instruments separation, dental microscope, ultrasonic technique
