Abstract

Objective: The aim of this work was to show the management of severe curvatures done with the new generation of rotating files through a safe and predictable protocol. Methods: Three clinical cases were described. A safe protocol was explained using the latest generation of rotating files for the shaping of the anatomy of complex root canals. All the cases presented 90°, 45° curvatures and/or double curvatures. Results: The instrumentation of canals increased their surface area and volume. All the cases with 90° and 45° curvatures were optimally shaped. Conclusion: With the help of rotating files in the martensitic alloy, it is possible to work safely, while avoiding the risk of file separation, even in root canals with severe curvatures, thus achieving success even in complex clinical cases.

Highlights

The goal of modern endodontics is to eliminate or reduce bacterial load inside the endodontic space, which is possible by performing adequate shaping and three-dimensional cleansing followed by filling with thermoplasticized gutta-percha [1 - 5]
The clinical introduction of Ni-Ti files presented a turning point in the history of endodontics. It allowed the production of new endodontic instruments, both manual and rotating, with better features than stainless steel ones [8]
Three clinical cases with serious curvatures are discussed which include cases shaped in maximum safety, next to the new rotary files, HyFlex EDM (Coltene/Whaledent, Langenau, Germany)

Summary

Introduction

The goal of modern endodontics is to eliminate or reduce bacterial load inside the endodontic space, which is possible by performing adequate shaping and three-dimensional cleansing followed by filling with thermoplasticized gutta-percha [1 - 5]. The clinical introduction of Ni-Ti files presented a turning point in the history of endodontics. It allowed the production of new endodontic instruments, both manual and rotating, with better features than stainless steel ones [8]. This invention led to the achievement of more effective and reproducible results. Ni-Ti alloys, used in dentistry, have a rational atomic composition of Ni-Ti, consisting of 55% of Ni and 45% of Ti [9, 10]
