Preparation and Characterization of Zinc Oxide Eugenol (ZOE) Cement for Dental Application

Zinc oxide eugenol (ZOE) cement is widely used in dentistry due to its excellent sealing ability, biocompatibility, sedative action on the pulp, and antimicrobial properties. However, its clinical use is often restricted because of weak mechanical strength and high solubility, limiting its application mainly as a temporary restorative material. The present research focuses on the preparation and characterization of ZOE dental cement aimed at improving its performance for potential extended clinical applications. In this study, ZOE cement was formulated by reacting zinc oxide powder with eugenol under controlled laboratory conditions. The physicochemical and mechanical properties of the prepared cement were evaluated using standard testing protocols, including setting time, compressive strength, surface microhardness, and solubility analysis. Characterization techniques such as Fourier-transform infrared spectroscopy (FTIR) and Scanning Electron Microscopy (SEM) were employed to analyze the structural composition and morphology of the cement matrix. The results demonstrated that optimized ZOE formulations exhibited improved mechanical behavior and reduced solubility while maintaining desirable biological properties. This study suggests that modification of ZOE composition can significantly enhance its functional properties, making it a promising material for broader dental applications. Further research is recommended to examine long-term clinical performance and biocompatibility enhancements.
