Methods for preventing fragmentation of endodontic instruments: a systematic review

https://doi.org/10.36377/ET-0144

Abstract

INTRODUCTION. Endodontics is one of the most dynamically developing areas of dentistry. The introduction of rotary instrumentation has revolutionized the mechanical treatment of the root canal system, significantly increasing the effectiveness of endodontic treatment. However, the incidence of complications associated with rotary instrumentation has also increased, the most common of which is file fragmentation. That is why it is really important to know the existing methods for preventing the occurrence of this complication.

AIM. To systematize the information presented in scientific articles on methods for preventing fragmentation of endodontic instruments during root canal preparation.

MATERIALS AND METHODS. A search of literature sources was carried out in the PubMed, dissercat.com, elibrary.ru, database.ru, cyberleninka.ru by keywords “endodontic treatment”, “iatrogenic events”, “fracture of endodontic instruments”, «prevention of an instrument fractures» with a choice of article types “Clinical Trial”, “Meta-Analysis”, “Review”, “Systematic Review”.

RESULTS. After analyzing the literature review, an idea about the methods of preventing instrument fragmentation in the root canal system was obtained.

CONCLUSIONS. Methods for preventing fragmentation of endodontic instruments are aimed at ensuring the safest possible operation of instruments in the root canal system; however, there is still no reliable way to prevent the occurrence of such a complication.
