Reabsorção cervical invasiva em dente com dens in dente: relato de caso

Abstract

An invasive cervical resorption is a type of external resorption with progressive and invasive characteristics, which can affect dental and periodontal structures such as the ligament, cement and dentin. This alteration was addressed in this work along with the dens invaginatus, a dental development anomaly that involves the invagination of the enamel tissue within dental papila. These alterations were detected on the patient of the case report through a tomography evaluation, lesion localization, trauma history of the patient, and other factors that will be presented in the review of this work. The treatment was finished in three sessions, where an ultrassound equipment and inserts were used for access and cleaning of the affected region, the operating microscope helped on the visualization of the inflammatory granulation tissue, as well as two changes of calcium hydroxide paste root canal dressings. The obturation was done the conventional way respecting the lesion’s limits, where the resorption communication was sealed with MTA HP Repair (Angelus) up until the cervical third of the canal. Considering the difficulty of diagnosis in the daily routine of dentists and the resolution of certain cases of invasive cervical resorption, and also the questionable prognosis of these, it was considered relevant to report a case, in this monography, describing the steps of the treatment performed on a patient, as well as a literature review on the topic. The patient attended was referred to the specialization of endodontics course of the dental school/UFMG due to the presence of a resorption pathology on the middle third of the superior right lateral incisor, associated with a dens invaginatus, observed in a CBCT scan obtained at the radiology service of the institution.
