Abstract

ABSTRACTExternal cervical resorption is caused, almost exclusively, by dental trauma - especially those characterized by concussion - and is a dental disease to be diagnosed and treated accurately by endodontists. However, the vast majority of the cases is initially diagnosed by an orthodontist, due to the imaging possibilities in standardized documentations. Among the causes of external cervical resorption, it is common to mistakenly attribute it to orthodontic treatment, traumatic occlusion or even to chronic inflammatory periodontal disease. External cervical resorption is associated to dental trauma in several situations mentioned in this paper. In old cases, and eventually still nowadays, it may have been induced by internal tooth bleaching, which is increasingly less frequent in endodontically treated teeth. There are some tips to be followed and some care that must be taken during the diagnosis and treatment of external cervical resorption clinical cases. The present study lists foundations that will allow the professional to perform safely and accurately in each specific case. Some of these tips and care measures are of orthodontic nature.

Highlights

A reabsorção cervical externa é provocada, quase exclusivamente, pelo traumatismo dentário, especialmente os do tipo concussão
Some dental clinicians often question whether dental resorptions have been diagnosed more than they used to be, or if their frequency has been increasing
Dental resorptions have been increasingly diagnosed in the clinical planning of all specialties due to the following: 1) People having more access to advanced means of diagnosis, that is, digital radiography and computed tomography with 3D reconstruction and slices in all directions and plans

Summary

Introduction

A reabsorção cervical externa é provocada, quase exclusivamente, pelo traumatismo dentário, especialmente os do tipo concussão. The available options for an efficient bleaching that does not harm the dental tissues nor represent risks of external cervical resorption are almost a unanimous choice, even in those cases of discoloration of teeth endodontically treated.
