Effect of zinc oxide nanoparticles on total salivary peroxidase activity of human saliva (In vitro study)
Main Article Content
Abstract
Materials and methods: Forty eight unstimulated saliva samples were collected from dental students/University of Baghdad 18-22 years. Then measure the total salivary peroxidase activity first without any addition to human saliva as a control, second with dilution the saliva with de-ionized water, and third with zinc oxide nanoparticles in concentration (5.8 mg/ml).
Results: The results showed that there was significant inhibition of the activity of the total salivary peroxidase enzyme in the presence ZnO NPs and non-significant inhibition of enzyme activity in the presence de-ionized as compared with control group.
Conclusion: Zinc oxide nanoparticles have inhibition effect on total salivary peroxidase activity
