Escurecimento induzido por cimentos endodônticos: uma revisão narrativa

Abstract

INTRODUCTION: Color variation after endodontic treatment is a challenge to clinical practice and is often related to endodontic sealers. OBJECTIVE: Carry out a survey of the main cements used in endodontic treatment, analyzing the interaction with blood and auxiliary chemical substances, as well as the radiopacifier present.. MATERIALS AND METHODS: A selection of articles published in English on this topic on the search platforms Pubmed, Medline, Elsevier and Bvsalud was carried out, considering the period from 1986 to 2023, with the aim of analyzing a greater variety of materials. RESULT: It was observed that most of the cements tested promoted color changes, especially those based on zinc oxide-eugenol and mineral trioxide aggregate. Furthermore, the studies analyzed revealed that blood contamination significantly increased the darkening associated with all materials, as well as the association of cements containing bismuth oxide with sodium hypochlorite also corroborated greater darkening. CONCLUSION: Bioceramic materials demonstrate minimal color changes, in contrast to cements based on zinc oxide and eugenol, and those based on MTA, which cause the most significant changes. Furthermore, an increase in darkening is evident when combining all cements with blood, and in some cases, with sodium hypochlorite.
