In present study, zinc oxide nanoparticles were synthesised using Syzygium aromaticum andcharacterized using UV visible spectroscopy, SEM, XRD and FTIR techniques. The characteristichexagonal structure of the ZnO nanoparticles was confirmed through XRD analysis. The UV-Visiblespectrum showed a strong absorbance at 366 nm confirming the presence of ZnO and the peak at 496cm-1 in FTIR indicated the Zn-O stretch bond. Average size of the zinc oxide nanoparticles obtainedfrom SEM analysis was found to be 86 nm. The zinc oxide nanoparticles exhibited better antibacterialactivity than clove extract, when tested against clinical isolates of Streptococcus mutans. Thenanoparticles incorporated into the dental restorative material, glass ionomer cement (GIC) were testedagainst S. mutans and exhibited better antibacterial activity than clove extract. Glass ionomer cement(GIC) did not exhibit antibacterial activity alone, but the incorporation of ZnO nanoparticles into GICsignificantly improved antibacterial activity. Hence, ZnO embedded GIC is a promising material inrestorative dentistry for preventing the recurrence of dental caries.
