“… 67 A noteworthy finding was that among the six major predisposing factors (bruxism, trauma, eruption disorders, extraction of an adjacent tooth, orthodontic treatment, and restoration) taken into account, trauma was the only factor which showed a significant difference between the ECR group and the control group. 66 However, in view of the study’s small sample size as well as its higher age distribution, the researchers did not draw valid conclusions regarding the differences between the relevance rate of post-orthodontic ECR. 66 …”

External cervical resorption (ECR) refers to a pathological state in which resorption tissues penetrate into the dentin at the cervical aspect of the root. Despite being latent in its initial phase, ECR could cause severe damage to mineralized dental tissue and even involve the pulp if not given timely diagnosis and treatment. Nevertheless, the etiology of ECR is still poorly understood, which adds to the difficulty in early diagnosis. ECR has received growing attention in recent years due to the increasing number of clinical cases. Several potential predisposing factors have been recognized in cross-sectional studies as well as case reports. In the meantime, studies on histopathology and pathogenesis have shed light on possible mechanisms of ECR. This review aims to summarize the latest findings in the pathogenesis and potential predisposing factors of ECR, so as to provide pragmatic reference for clinical practice.

“…A recent retrospective case-control study showed that the prevalence of ICR was 2.3% based on a 10-year observation of endodontic patients at the university clinic [ 3 ]. The disease prevalence of ICR is closely associated with predisposing factors that can cause the loss of the protective layers.…”

“…Another recent study showed that predisposing factors were detected in 99% of ICR cases [ 36 ]. The maxillary anterior teeth were highly affected among all tooth types [ 3 , 18 , 36 ], implying that mechanical and chemical predisposing factors such as traumatic injuries and internal bleaching could be more frequently associated with this tooth type. No predilection for patients’ age and sex was identified in clinical studies [ 18 , 36 ].…”

“…Invasive cervical resorption (ICR) is a pathologic resorptive process that initiates on the external surface of a tooth above alveolar bone crest and gradually replaces mineralized tooth structure with granulomatous fibro-vascular tissue or fibro-osseous tissue. It is a rare disease of which the prevalence ranges from 0.02% to 2.3% [ 1 , 2 , 3 ], but often leads to tooth loss due to its insidious and asymptomatic nature. The resorptive process of ICR is preceded by the loss of unmineralized precementum layers of the root and characterized by the presence of inflammation and odontoclastic activities below the epithelial attachment of gingiva.…”

The Disease Process, Diagnosis and Treatment of Invasive Cervical Resorption: A Review

2020

View full text Add to dashboard Cite

Invasive cervical resorption (ICR) is a localized, subepithelial, supra-osseous resorptive process of the tooth. Although there are several predisposing factors associated with ICR, its etiology and pathogenesis are poorly understood. The damage to the protective layer on the external root surface appears to allow for the attachment of clastic cells and initiate the resorptive process, which is confined by the inner protective pericanalar resorption-resistant sheet surrounding the root canal space. The use of cone-beam computed tomography (CBCT) is recommended for the diagnosis and assessment of a resorptive lesion. Based on the thorough evaluation of the size and location of the ICR lesion using CBCT, surgical or nonsurgical treatment can be chosen to address the source of the resorption. This review discusses the current status of knowledge regarding the biology of ICR lesions as well as their external or internal treatment using hydraulic calcium silicate-based materials. Future clinical outcome studies are necessary to evaluate the impact of hydraulic calcium silicate-based materials on the healing of ICR lesions.

Key clinical messageA successful management of an advanced external cervical resorption using a conservative approach with CBCT, dental operating microscope, and a new bio‐ceramic material.AbstractExternal cervical resorption (ECR) is a pathologic condition that is initiated on the external aspect of the root, below the epithelial attachment in the cervical position. This article will report a case of external cervical resorption (ESR) in an advanced stage, which was asymptomatic and was incidentally detected in a follow‐up radiograph after the end of orthodontic treatment. Cone‐beam computed tomography (CBCT) was prescribed to accurately diagnose the resorptive lesion and differentiate it from internal root resorption (IRR), and the final diagnosis was Heithersay's class IV ECR. Considering the health of the periodontium and the absence of attachment loss, it was decided to use a conservative internal approach to the management of this case. After the treatment, the patient was asymptomatic and the radiographic examinations showed no signs of peri‐radicular pathology during the follow‐up period. With the correct case selection and the availability of the appropriate materials and equipment such as a dental operating microscope (DOM) and bio‐ceramic materials, the internal approach can be a successful and minimally invasive treatment, even for the management of advanced ECR cases.
