Strategies for intracanal separated instrument removal: a review

Abstract

The successful removal of a separated instrument from the root canal depends on various factors. The location of the broken fragment must be determined because that is commonly the most important factor in determining successful retrieval of the fragment. A variety of different methods for removing obstructions have been described in the literature. However, guidelines for the removal of a separated instrument have not been established. This review aims to describe the methodological approaches to adopt for removing an intracanal separated instrument, depending on the clinical situation, both when the fragment extends into the pulp chamber and two-thirds of the way down the root canal. CPD/Clinical Relevance: This paper aims to describe the methodological approaches to adopt for removing an intracanal separated instrument, depending on the clinical situation.

Management of Separated Instruments Within Root Canals.

“…Although a lot of techniques [24][25][26][27][28][29][30] and retrieval kits are out in the market a lot of practice and experience is required to master the skill of retrieval of instruments. The retrieval of the instrument should be done with minimal dentine removal.…”

Electrochemical dissolution and retrieval of broken NiTi endodontic files from root canal using chloride based isotonic fluids as electrolytes − An in vitro study

“…[ 8 ] There are many methods for instrument retrieval. [ 9 ] However, most of these techniques have limitations, and there may be a chance of excessive loss of dentine, ledge formation, and perforation. [ 10 ] An alternate method of electrochemical dissolution was developed.…”

Frequency of Procedural Errors during Root Canal Treatment Performed by House Officers in Private Teaching Dental Hospital

“…A study by Alsulaimani R 2016 9 on the correlation between endodontic mishaps and single-visit treatment amongst dental students was conducted in King Saud University Saudia Arabia showed the apical transportation as the most prevalent procedural error (39%) followed by ledge (34.5%). A number of factors can affect the perception, clinical efficiency and performance of Interns 10,11 . The procedural errors can be avoided by a dentist by relying on his knowledge, intuition, and patience during the course of the treatment.…”
