INSTRUMENT RETRIEVAL WITH A NEW FILE-REMOVAL SYSTEM: CASE REPORTS

Abstract

There are various methods and devices developed to remove separated instruments. However, each method and each device varies in separated file removal time and dentin sacrifice. None of them has been perfect for predictable outcomes due to the limitations of the usage. A novel file removal system was developed to maximize the success in separated file removal and minimize the iatrogenic events. This article illuminates the technique to remove a separated instrument with the newly developed system. Three difficult-looking cases were presented here for separated file removal and all of the three separated files were retrieved with the new technique, which would not have been possible if it had not been for the new file removal system. The postoperative radiographs in comparison with the preoperative radiographs show the minimum dentin sacrifice and safe removal in all the three cases. All the separated instruments were retrieved within 6 minutes, indicating the technique applied to those cases was efficient with predictable outcomes.
