Evaluation of the Coating with TiO₂ Nanoparticles as an Option for the Improvement of the Characteristics of NiTi Archwires: Histopathological, Cytotoxic, and Genotoxic Evidence

Figure 4

Deposited arches. It is observed that, at higher voltage/deposition time, there are more deposited TiO₂ NPs, but there is also an increase in surface fractures ((f) and (g)) (10x).
