Clareamento dentário em dentes anteriores com descoloração coronária tratados endodonticamente: uma revisão de literatura

Abstract

Introduction: The importance of aesthetics and the desire for smile harmony is becoming an important component of dental practice. Discoloration or staining of just one tooth, especially in the anterior region, causes great aesthetic damage and dissatisfaction for the patient. Internal whitening appears as a conservative solution for discoloration of endodontically treated teeth. Objective: Therefore, the present study aimed to carry out a literature review on the whitening of devitalized teeth, covering techniques, whitening agents available on the market and possible risks. Methodology: The search for this review was carried out in the Pubmed and Google Scholar databases, including freely accessible works that discuss the topic, and excluding escapes from the central theme and repeated articles. Result:Through the research it was possible to verify that there are three techniques widespread in the literature: mediate, immediate and mixed. It is up to the dentist to assess which one best fits the patient's clinical condition. As for whitening substances, sodium perborate is the most recommended by the authors, being considered safer than hydrogen peroxides and carbamide peroxides. Conclusion: The whitening of non-vital teeth using the techniques described in the literature demonstrates clinical success and interesting longevity. In this way, it becomes an effective non-invasive treatment option, promoting favorable aesthetic results and contributing to the patient's well-being. However, new studies are needed to improve techniques and substances to optimize the procedure.
