General review of titanium toxicity
Titanium is a commonly used inert bio-implant material within the medical and dental fields. Although the use of titanium is thought to be safe with a high success rate, in some cases, there are rare reports of problems caused by titanium. In most of these problematic reports, only individual reports are dominant and comprehensive …

Titanium Dioxide
Titanium dioxide (TiO 2) is the white pigment used to give whiteness and hiding power, also called opacity, to coatings, inks, and plastics. The reason for this is two-fold: TiO 2 particles of the right size scatter visible light, having wavelength λ ≈ 380 - 700 nm, effectively because TiO 2 has a high refractive index.
