Abstract

Background: Any reduction in friction between the orthodontic wire and the bracket can speed up tooth movement in the sliding technique and result in improved 3-D control. The purpose of this study was to investigate frictional forces caused by covering orthodontic wires and brackets with silver oxide nanoparticles (AgO).
Materials and Methods : In this study, 30 brackets (0.022 × 0.028” slot) and 30 arch wires (0.019 × 0.025” SS wires) were taken and split into 3 groups. The first group included uncoated arch wires and brackets. The second group included uncoated arch wires and coated brackets. The third group included coated arch wires and coated brackets. These brackets were further examined under Scanning electron microscopy to evaluate the AgO nanoparticle coating and its thickness. These brackets and wires were then subjected to a friction test with the help of a UNIVERSAL TESTING MACHINE. Frictional forces were statistically analysed using One-way ANOVA test followed by Tukey’s HSD Post hoc Analysis.
Results: Coating with AgO nanoparticles significantly influenced frictional force values (P < 0> The second group showed 0.4815 ± 0.0840 N. The third group showed 0.2010 ± 0.0445 N. This mean difference in the Frictional force between 3 groups was statistically significant.
Conclusion : AgO nanoparticles may be a unique way to dramatically reduce friction during tooth movement because of their beneficial impacts on lowering frictional forces.
