Surface Effect of Nano-Roughened Yttria-Doped Zirconia on Salivary Protein Adhesion

Biocompatibility of yttria (3 mol%) stabilized zirconia ceramics, 3Y-TZP, was affected to a large degree as a result of protein adsorption from human saliva that in turn depends on materials surface properties. Variable nano-roughness levels in 3Y-TZP discs were characterized and tested for specificity and selectivity with respect to size and uptake for human salivary protein.

Automated summary

The biocompatibility of yttria (3 mol%) stabilized zirconia ceramics, 3Y-TZP, is significantly affected by protein adsorption from human saliva, which depends on the material's surface properties. Variations in nano-roughness levels of 3Y-TZP discs were tested for their specificity and selectivity towards size and uptake of human salivary protein.
