Photocatalytic treatments on dental mirror surfaces using hydrolysis of titanium alkoxide

Anatase titanium dioxide (TiO₂) photocatalytic thin films were directly formed on glass slide and commercial dental mirror substrate surfaces by a hydrolysis of titanium alkoxide, and the hydrophilicity, the degree of oxidizing power and the transparency of the anatase TiO₂-coated substrate surfaces. The contact angles of water and the decomposition rates of methylene blue on the anatase TiO₂ photocatalytic thin films improved with the increasing duration of a tetraethyl orthotitanate (TEOT) hydrolysis, but they hardly changed for the longer duration. The reflectance of anatase TiO₂ photocatalytic thin films coated on glass slide substrate surfaces was higher as the duration of a TEOT hydrolysis increased. Similar tendencies concerning hydrophilicity and transparency were recognized in cases of commercial dental mirror substrate surfaces. A hydrolysis of titanium alkoxide obtained superhydrophilic and antibacterial treatments with excellent transparency on commercial dental mirror substrate surfaces.
