          Abstract

          Invasive cervical resorption (ICR) is an aggressive and invasive form of external tooth resorption that commences in the cervical region which can be managed using either a nonsurgical, surgical or a combination of nonsurgical and surgical approach. The restoration of resorptive defects having a coronal and radicular extent can be challenging as a single material cannot be used to restore the entire defect. This case presented with Heithersay's Class 3 ICR lesion in tooth #12, which was managed initially using a surgical approach and restoration of ICR defect with a combination of resin modified glass ionomer cement, composite resin and mineral trioxide aggregate (MTA). However, the patient presented with pulpal symptoms 2 months later which warranted a root canal therapy. An internal approach was then used to debride and remove remnant fibro-osseous tissue. The defect was then repaired with MTA. A 1 year follow-up demonstrated adequate periapical healing and no pathologic changes around the restored resorptive defect.

          Internal root resorption: a review.

          Internal root resorption is the progressive destruction of intraradicular dentin and dentinal tubules along the middle and apical thirds of the canal walls as a result of clastic activities. The prevalence, etiology, pathogenesis, histologic manifestations, differential diagnosis with cone beam computed tomography, and treatment perspectives involved in internal root resorption are reviewed. The majority of the documentation that exists in the literature is in the form of case reports, and there are only a limited number of studies that attempted to examine the histologic manifestations and biologic aspects of the disease. This might be due, in part, to the relatively rare occurrence of this type of resorption and the lack of an in vivo model, apart from the previous attempt on the use of diathermy, to predictably reproduce the condition for study. From a histologic perspective, internal root resorption is manifested in one form that is purely destructive, internal (root canal) inflammatory resorption, and another that is accompanied by repair, internal (root canal) replacement resorption that is featured by the deposition of metaplastic bone/cementum-like tissues adjacent to the sites of resorption. From a differential diagnosis perspective, the advent of cone beam computed tomography has considerably enhanced the clinician's capability of diagnosing internal root resorption. Nevertheless, root canal treatment remains the treatment of choice for this pathologic condition to date. Copyright 2010 American Association of Endodontists. Published by Elsevier Inc.

            Invasive cervical resorption: an analysis of potential predisposing factors.

            An investigation was undertaken to assess potential predisposing factors to invasive cervical resorption. A group of 222 patients with a total of 257 teeth displaying varying degrees of invasive cervical resorption were analyzed. Potential predisposing factors, including trauma, intracoronal bleaching, surgery, orthodontics, periodontal root scaling or planing, bruxism, delayed eruption, developmental defects, and restorations were assessed from the patients' history and oral examination. Of the potential predisposing factors identified, orthodontics was the most common sole factor, constituting 21.2% of patients and 24.1% of teeth examined. Other factors were present in an additional 5.0% of orthodontically treated patients (4.3% of teeth), and these consisted principally of trauma and/or intracoronal bleaching. Trauma was the second most frequent sole factor (14.0% of patients and 15.1% of teeth). Trauma in combination with intracoronal bleaching, orthodontics, or delayed eruption constituted an additional 11.2% of patients (10.6% of teeth). Intracoronal bleaching was found to be the sole potential predisposing factor in 4.5% of patients and 3.9% of teeth, and an additional 10.4% of patients and 9.7% of teeth showed a combination of intracoronal bleaching with trauma and/or orthodontics. Surgery, particularly involving the cementoenamel junction area, was a sole potential predisposing factor in 6.3% of patients and 5.4% of teeth. Periodontal therapy, including deep root scaling and planing, showed a low incidence, as did other factors, such as bruxism and developmental defects. The presence of an intracoronal restoration was the only identifiable factor in 15.3% of patients and 14.4% of teeth, while 15.0% of patients and 16.4% of teeth showed no identifiable potential pedisposing factors. These results indicated a strong association between invasive cervical resorption and orthodontic treatment, trauma, and intracoronal bleaching, either alone or in combination.
