CBCT Post-Processing Tools to Manage the Progression of Invasive Cervical Resorption: A Case Report

Abstract

This case report aimed to highlight the usefulness of cone beam computed tomography (CBCT) and its post-processing tools for the diagnosis, follow-up and treatment planning of invasive cervical resorption (ICR). A 16-year-old female patient was referred for periapical radiographic examination, which revealed an irregular but well demarcated radiolucency in the mandibular right central incisor. In addition, CBCT scanning was performed to distinguish between ICR and internal root resorption. After the diagnosis of ICR, the patient was advised to return shortly but did so only six years later. At that time, another CBCT scan was performed and CBCT registration and subtraction were done to document lesion progress. These imaging tools were able to show lesion progress and extent clearly and were fundamental for differential diagnosis and treatment decision.

External cervical resorption – Treatment outcomes and determinants: A retrospective cohort study with up to 10 years of follow‐up

“…For optimal evaluation of the change in the size of the ECR, CBCT scan assessment should ideally be used. The digital subtraction radiography technique has been used in a case report (Vasconcelos et al, 2016). A more recent study utilized CBCT scans and provided a volumetric assessment of the ECR (Matny et al, 2020).…”

Conservative Restorative Management of External Cervical Tooth Resorption: A Case Report

“…Several case reports mentioned that their patients had previously undergone orthodontic treatment, suggesting that this could be a contributing factor. It is demonstrated that previous orthodontic treatment may have damaged the cementum layer, exposing the dentin and stimulating the clastic cells to resorb the dentin [12,14,23]. Two different studies found that orthodontic treatment is the most common predisposing factor, with (21.2%) and (45.7%), respectively [7,15].…”

“…ECR defects are quite challenging to diagnose and manage due to the inconspicuous clinical signs and symptoms and rapid progression [4,23]. They are usually asymptomatic until they reach the pulp [24].…”

Cone Beam Computed Tomography and Virtual Cloning: A Review

“…3D CBCT follow-up is suggested for possible depiction of peri-implantitis, implant failure, healing of periapical pathosis, depiction of the biomaterial behavior, monitoring after sinus augmentations, to determine the outcome of cleft palate graft outcomes, and to invigorate the rate of condylar changes with possible erosion or decalcification. 32 33 34 35…”
