DIFFERENCES IN TOOTH DISCOLORATION BETWEEN ZINC OXIDE EUGENOL AND MINERAL TRIOXIDE AGGREGATE-BASED SEALERS (LITERATURE STUDY)

Endodontic treatment is a common procedure in dentistry. One of the steps in endodontic treatment is obtura-tion root canal, that needed application sealer to seal the gap between dentin's wall and gutta-percha and lubricate the root canal's wall during treatment. Sealer can cause discoloration because of their compositions such as eugenol, phenol, and silver that is potential in causing color alteration. Objective: to analyze the discoloration difference in application using ZOE sealer and MTA sealer. Method: Journals, textbooks, and websites published between 2010 – 2020 and can be accessed from Google Scholar, National Library of Indonesia, EBSCO, and PubMed are used as source of this literature review. Conclusion: Both of the sealer cause discoloration because of their composition such as zinc oxide and eugenol that caused continuous oxidation in ZOE sealer and bismuth oxide which interacts with dentin in MTA sealer. Application of MTA is recommended because of their minimal color alteration compared to ZOE sealer, and their excellent physical properties and biocompatibility
