Metal oxide nanoparticles are known as a new class of important materials that have been implemented for various applications such as biomedical imaging, drug delivery, and other healthcare related fields. In dentistry, bulk zinc oxide particles have been used for temporal or permanent luting cement due to their excellent mechanical strength and biocompatibility. Among these, zinc phosphate cement exhibits excellent compressive strength, while the zinc polycarboxylate cement presents chemical bonding to tooth mineral surfaces. With the advancement of nanotechnology, zinc oxide nanoparticles with different crystal structures and conformation have been synthesized. The zinc oxide nanoparticles possess smaller size and higher surface area compared with their bulk counterparts. As a result, the zinc oxide nanoparticles are more active in antibacterial activity, and they act as fillers to enhance the density and to reduce the porosity of the zinc oxide contained materials. These properties might have certain niches to use zinc oxide nanoparticles to replace a part of the bulk zinc oxide particles of current cements, and thus it improves the overall properties of the cements. In the present study, it was aimed to improve the antibacterial property of luting cement as a solution for preventing the failure of dental restoration, the development of secondary caries and (or) periodontitis in the tooth-prosthetic junction when attacked by cariogenic bacteria. It was discovered that antibacterial activity was significantly improved when more than 10% of the synthesized zinc oxide nanoparticles were used to replace a part of the bulk particles of conventional zinc oxide polycarboxylate cement. In addition, mechanical properties of zinc oxide nanoparticles contained cement were better than that of conventional zinc oxide polycarboxylate cement. In conclusion, this study presented a new dental luting cement system with integrated nano-ZnO that provides a promising solution for potential prevention of secondary carries and periodontitis. The discovery of this study could simultaneously contribute to the concept for future improvement of dental restorative cement with build in antibacterial and better mechanical properties.
