Effect of Titanium Dioxide Nanoparticles (Tio2NPs) on Entamoeba gingivalis in vitro

Abstract

The effect of Titanium Dioxide Nanoparticals (Tio2NPs) on Entamoeba gingivalis in vitro were studied, which isolated from gums in gingivitis patients who attended the periodontal disease department at the Faculty Dentistry of Mosul University for the period from 1/4/2018 to 31/7/2018.In our study three different concentrations of (Tio2NPs) were prepared as the following order: (0.1, 0.01, 0.001) mg/ml and evaluated the effect of these different concentrations through (2,4,6) hours. Results showed that time factor and the increasing of the appositive effect on the parasite killing and the highest concentration (0.1mg/ml) had a role in inhibition of parasite growth and reduced parasite survival rate to (3.60±0.953) compared to the other concentrations. Also in this present study we found the concentration (0.1 mg/ml) was the highest inhibition of parasite (86.73%) in the time period at (6 hours) compared to other concentrations and periods time which showed slight differences between them.
