Is zinc oxide eugenol cement still impeding the use of resin-based restoration? A systematic review

Abstract

Background: The use of zinc oxide eugenol (ZOE), along with resin restoration or cementation, is often a debatable topic in dentistry. This systematic review is aimed to explore the effect of ZOE on various properties of resin-based dental materials. Materials and Methods: An electronic research was carried out using the relevant keywords in different search engines such as MEDLINE/PubMed, Ebscohost, SCOPUS, Web of Science, and EMBASE SciFinder based on PRISMA guidelines. Only articles in the English language were included along with other specific inclusion criteria. Results: The entire articles were assessed for the eligibility and final review included 30 studies that were then classified according to the type of test conducted on the resin-based material. Conclusion: There is no consensus on the deleterious effect of ZOE on resin-based dental material. However, all the tests conducted were in vitro and most of them showed a significant reduction in the quality of resin restorative and cement materials when used with ZOE.
