2 de nov. de 2020 · Broken instruments are not a reason for apical periodontitis. The proposed clinical algorithm is based upon the understanding of biological processes that are responsible for periapical lesions and tooth biomechanics. Its goal is the maintenance of a long-term functional tooth. 18. If Instrument was broken in a canal with:

where the withdrawal of a broken endodontics instrument, which passed through the apex in a teeth with periapical lesion was done by using a simple and accessible technique. The advantages are the preservation of dental structure and the elimination of apical surgery. Descriptors: Root canal therapy, endodontic retreatment, instrument fracture.

When the success rate of broken instrument removal was investigated regarding the location of the broken instrument in the canal, 100% success rate was obtained in coronal third of the all canals. This findings collaborated the results of Ward et al’s. 12 However lower success rate was found by Hulsmann and Schinkel 7 and Nagai et al. 4 The success rate was found the lowest in the apical third.
