Advancements in Diagnosing and Treating External Invasive Cervical Resorption: A Comprehensive Study on Biocompatible Materials and Finite Element Analysis

External Invasive Cervical Resorption (EICR) is an erosive dental disease in which the hard structures of the cervical region of teeth are deteriorated by specialized cells. The active disease process tends to progress asymptomatically, and its early identification by clinicians is problematic. The lesion is more concentrated towards the cervical part of the teeth, where the crown meets the root. Most modern diagnostic methods rely on Cone-Beam Computed Tomography (CBCT) to provide three-dimensional views of ECR lesions in unprecedented detail. A high-tech imaging centre of this nature enables practitioners to arrive at accurate estimates of the severity of tissue loss, assess invasion of the pulp, and treat in proportion. Successful treatment of ECR has three principal objectives: removal of resorptive tissue, replacement of compromised hard tissue structure with biocompatible substances, and prevention of recurrence. Treatment ranges from non-surgical external and internal repair to more invasive ones like endodontic therapy, intentional replantation, or extraction in the event of a non-restorable tooth. The treatment process is generally based on the site and degree of resorption. Some newer-generation repair materials like Mineral Trioxide Aggregate (MTA) and Biodentine have also been demonstrated to successfully lead to periodontal reattachment and long-term success. These biocompatible materials seal and are more compatible with the tissue than the conventional ones. The current study employed Finite Element Analysis (FEA) to evaluate stress patterns in ۲BP category ECR lesion-damaged maxillary central incisors.  These results are of considerable value to clinicians when selecting the most appropriate treatment modes and materials in an effort to optimize the long-term success of involved teeth from this pathologic process.
