| Abstract: | Objective： To evaluate the clinical effect of microsonic technique on removal of 1/3 intracanal separated instruments. Methods： A total of 36 cases with broken instruments were endodontically treated with ultrasonic in- strument under dental operating microscope form February 2007 to July 2012. Results： Totally 29 fractured instru- ments were completely removed with a middle one--third and apical one--third of root canals in 36 cases, 4 cases formed bypath in canal, 1 case was pulled. Conclusion： The use of dental microscope and ultrasonic is proved to be an effective and safe method for fractured metallic instruments removal |
