Influence of the composition of gases during surface modification of plasma cell primary adhesion in the dental pulp.
Abstract
Samples of titanium were nitrided using plasma and a composition of two gases: 80% H2-20% N2 and 20% H2-80% N2. The influence of these treatments on
their physical chemical properties and biological response when subjected to the primary cell culture of dental pulp were studied. Analyses by X-ray diffraction indicate the formation of TiN in both nitrided samples in contrast to the non-nitrided surface samples that contained only the Ti-? phase. Changes in hardness, topography and wettability of these samples compared to non-nitrided
samples were found as well. Finally, the analysis of cell’s adhesion in these samples indicate that treatment increases its value being higher for samples treated at higher hydrogen concentration
