Abstract EN
It is postulated that biofilm formation in the oral cavity causes some oral diseases.
Lactoferrin is an antibacterial protein in saliva and an important defense factor against biofilm development.
We analyzed the adsorbed amount of lactoferrin and the dissociation constant (K d) of lactoferrin to the surface of different dental materials using an equilibrium analysis technique in a 27 MHz quartz crystal microbalance (QCM) measurement.
Four different materials, titanium (Ti), stainless steel (SUS), zirconia (ZrO2) and polymethyl methacrylate (PMMA), were evaluated.
These materials were coated onto QCM sensors and the surfaces characterized by atomic force microscopic observation, measurements of surface roughness, contact angles of water, and zeta potential.
QCM measurements revealed that Ti and SUS showed a greater amount of lactoferrin adsorption than ZrO2 and PMMA.
Surface roughness and zeta potential influenced the lactoferrin adsorption.
On the contrary, the K d value analysis indicated that the adsorbed lactoferrin bound less tightly to the Ti and SUS surfaces than to the ZrO2 and PMMA surfaces.
The hydrophobic interaction between lactoferrin and ZrO2 and PMMA is presumed to participate in better binding of lactoferrin to ZrO2 and PMMA surfaces.
It was revealed that lactoferrin adsorption behavior was influenced by the characteristics of the material surface.
