摘要/Abstract

摘要： 器械分离是根管治疗最容易发生的并发症之一,也是牙体牙髓科医生经常面临的挑战。本文报道1例采用显微超声技术取出右上颌第二磨牙腭侧根管内分离器械,并完善根管治疗的病例。显微超声技术是根管内分离器械取出的有效方法之一。

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
