Abstract

Teeth with extraordinary length are a rare condition that complicates endodontic procedures due to the difficult in being reached the working length and making the adequate preparation of the root canal, once there are no endodontic instruments longer than 31 mm commercially available. This study presents a description of technical adaptations for endodontic preparation of a maxillary canine with 39.59 mm of length. The procedures adopted were based on the consultation of the literature regarding the treatment of long teeth, and included endodontic instrument adaptation and changing the reference point of the instrument. This study shows that extremely long teeth can be successfully instrumented endodontically using the described clinical techniques.

Highlights

The knowledge of the root canal morphology and its variations is an indispensable prerequisite for the success of the root canal treatment (Vertucci, 2005)
The internal anatomy of root canals often does not reproduce the simplicity of the external anatomy of the tooth (Pécora, Sousa Neto, & Saquy, 1993)
The professionals should be ready to deal with such cases in the clinical practice, once the industry not offers options of endodontic instruments

Summary

Introduction

The knowledge of the root canal morphology and its variations is an indispensable prerequisite for the success of the root canal treatment (Vertucci, 2005). Canines teeth are not exception, and not always present an internal anatomy as simple as could be expected (Bolla & Kavuri, 2011; Pécora et al, 1993; Somalinga Amardeep, Raghu, & Natanasabapathy, 2014). The maxillary canines exhibit the greatest combined crown plus root length in each arch and their root is very firmly anchored in alveolar bone. Because of the thick bony support and the length of the root, the canines are usually the most steadfast teeth in the mouth (Sajnani, 2015). The mean length of maxillary canine is 26.5 mm, ranging from 20.0 mm to 32.0 mm (Burns & Buchanan, 1994). Studies have revealed the existence of extremely long canine, ranging from 41 to 52 mm in length (Booth, 1988; Hayward, 1980; Marashi & Gorlin, 1990; Wilkie & Chambers, 1990)
