Abstract
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.
Highlights
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
In order to capture the characteristics of this lesion, ICR has been described with various terms such as extracanal invasive resorption [5], supraosseous extracanal invasive resorption [6], external cervical resorption [7], peripheral inflammatory root resorption [8], subepithelial inflammatory resorption [9], and odontoclastoma [10]
In this study revealed that periapical radiographs had limited performance in the assessment of the radiographs showed significantly lower sensitivity and specificity than cone-beam computed tomography (CBCT) for the detection of size, circumferential spread and locations of the lesions compared with CBCT [43]
Summary
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. These materials have shown excellent biocompatibility with osteoinductive, cementoconductive and cementoinductive properties, which may promote the periodontal tissue regeneration or repair [11,12]. J. 2020, 8, 64 a growing body of literature concerning the repair of the lesions of ICR with selected hydraulic calcium silicate-based materials, which may allow for the more biocompatible restoration of the resorptive lesions that is conductive to periodontal tissue regeneration around ICR
