Removal of intracanal obstructions with ultrasound. Analysis of 206 cases.
Intracanal obstructions were removed with ultrasound in 206 cases, with a success rate of 97.08%. Six cases (2.92%) failed owing to broken endodontic instruments at the apical third or in the curved and fine canals. The success rate of retrieval of casting post-core or other foreign objects was 100%. Our experience proves that ultrasonic technique is more effective and safer than any other methods for the removal of intracanal obstructions.
