| Abstract: | Objective To evaluate the clinical effect of microsonic technique on removal of intracanal broken instruments and to discuss the method to improve the successful rate.Methods A total of 96 teeth with 101 intracanal broken instruments, which could not be successfully managed by conventional methods, were endodontically treated with ultrasonic instruments under dental operating microscope.Results Eighty-three broken instruments in 78 teeth were completely removed with a successful rate of 82.2%.Conclusion Be careful in the process of root canal treatment in the mandibular molar. It is useful to remove most of broken instruments in canals by dental operating microscope and ultrasonic instruments, with appropriate methods and instruments |
