Abstract

Invasive cervical resorption (ICR) is an insidious, aggressive, and asymptomatic form that can lead to destruction and even loss of the dental unit. ICR is somewhat uncommon, but it can affect any tooth, with the maxillary central incisors being the most affected. Even after numerous studies, the etiology is still unclear. There are some predisposing factors, including orthodontic treatment, trauma, and internal tooth whitening, which may occur in isolation or in conjunction with each other. This article reports a clinical case of ICR class 3 with a rosy discoloration at the cervical margin and the presence of a fistula associated with a history of trauma. This suspicion was raised after radiographic examination and confirmed by cone-beam computed tomography (CBCT), with treatment via an internal approach and endodontic treatment involving debridement of the resorptive areas and filling with a bioceramic repair material and suturing. After treatment, the patient remained asymptomatic, but the fistula was no longer present. Prospective observation at 10 months showed bone formation in the middle third and well-adapted material in the cervical region, with no resorptive tissue present.

Highlights

There are several predisposing factors, the etiology and pathogenesis are poorly understood
Heithersay (2004) classified Invasive cervical resorption (ICR) into classes for diagnostic purposes based on the extent of the lesion within the tooth: Class 1, a small invasive resorption lesion near the cervical area of the tooth with superficial penetration into the dentin; Class 2, a well-defined invasive resorption lesion that has penetrated near the coronal pulp chamber but with little or no extension into the root dentin; Class 3, a deeper invasion of the dentin by resorption tissue involving the coronal dentin and extending at least to the coronal third of the root; and Class 4, an invasive resorption process extending beyond the coronal third of the root canal
The identification and evaluation of the ICR lesions depends on the interpretation of radiographs, as they occur in subgingival areas and can spread axially, horizontally, and circumferentially as they penetrate the dentin (Gunst et al, 2013)

Summary

Introducion

Tooth resorptions are characterized by the destruction of mineralized tissue due to the activity of resorptive cells, resulting in the loss of tooth structures responsible for the protection and insertion of teeth into the alveoli. Heithersay (2004) classified ICR into classes for diagnostic purposes based on the extent of the lesion within the tooth: Class 1, a small invasive resorption lesion near the cervical area of the tooth with superficial penetration into the dentin; Class 2, a well-defined invasive resorption lesion that has penetrated near the coronal pulp chamber but with little or no extension into the root dentin; Class 3, a deeper invasion of the dentin by resorption tissue involving the coronal dentin and extending at least to the coronal third of the root; and Class 4, an invasive resorption process extending beyond the coronal third of the root canal. The purpose of this article is to describe the treatment of a Class 3 ICR in which treatment was performed with therapeutic success
