# Non-surgical Endodontic Management of Multiple Mishaps: A Case Report

## TL;DR

This case report describes a successful non-surgical retreatment of multiple endodontic issues using specialized tools and techniques.

## Contribution

The paper presents a novel approach to managing multiple endodontic mishaps using a dental microscope and specific instruments.

## Key findings

- Non-surgical retreatment successfully managed overextended gutta-percha and a separated file.
- A missed canal was effectively retreated using the ProTaper Retreatment Kit.
- Use of a dental microscope improved precision in root canal treatment.

## Abstract

The description of non-surgical retreatment is to eliminate all previous filling materials and correct any mishaps. An adequate understanding of root and canal morphology is a fundamental requirement for obtaining a favorable outcome in endodontic treatment. The endodontic diagnosis was previously treated through therapy with symptomatic apical periodontitis. Treatment was performed under a dental operative microscope. Gates Glidden (GG) drills size 2 and 3 were used to remove the coronal part of gutta-percha for all canals. A braiding technique with a Hedstrom file size 15 without a solvent was used to remove gutta-percha and separate the file together for the palatal canal whereas the mesiobuccal canal was retreated by ProTaper Retreatment Kit. Proper understanding of root canal morphology and using an endodontic armamentarium could reduce endodontic mishaps. This case report described the successful management of overextended gutta-percha, a separated file, and a missed canal.
