“…It seems that the removal of fractured NiTi instruments is more influenced by factors such as degree of root canal curvature, radius of curvature, location of the fragment, and length of the fragment than the specific technique used (32). A clinician with more experience in separated file removal usually shows a higher success rate with less removed dentin structure than an inexperienced one (35).…”

“…The mechanical retrieval of fractured instruments from root canals has been largely reported in the literature, and many devices and methods have been proposed to accomplish that (8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20). However, those methods present some limitations related to canal morphology, reduction of root strength, and operator ability (6,7,16,19,(21)(22)(23)(24)(25)(26)(27). Consequently, a less complex retrieval method that causes minimum damage to the dental structures is necessary.…”

Introduction: A recent study presented the concept of an electrochemical-induced dissolution technique of fractured instruments. The purpose of this study was to test the ability to dissolve embedded fragments of K3 nickel-titanium (NiTi) files. The surface of the fragment exposed to the electrolytic solution was the main parameter evaluated as an interfering factor on the dissolution process. Methods: Three types of K3 NiTi 30.06 file fragments were produced, resulting in different exposed cross-section areas. Anodic current was recorded and used as a reference to evaluate the dissolution process of the fragments. Analysis of variance (P < .05) was used to compare the total electrical charge obtained from current versus time records among the fragments of the 3 groups. Radiographic analysis was carried out before and after the tests to observe the extension of dissolution achieved. Results: The total electrical charge values generated during the tests evidence a statistical difference among the 3 groups of fragments (analysis of variance, P < .05). The larger is the diameter of the exposed surface cross section, the higher is the total value of electrical charge. The radiographic images obtained before and after the tests showed a significant reduction of the fragment length as a result of the polarization imposed. Conclusions: The results presented here showed that it is possible to obtain a significant dissolution of K3 NiTi endodontic instrument fragments. The diameter of the surface of fragment exposed to the medium affects the current levels used to promote the dissolution. (J Endod 2011;37:526-530)
