A transmission electron microscopy study of the adsorption patterns of early developing artificial pellicles on human enamel.
Adsorption patterns of pellicles formed in a flow cell system under a moderate shear rate of 21 s-1, were studied with a replica technique. Characteristic features of the bare enamel surface disappeared within seconds after exposure to reconstituted saliva, indicating the adsorption of a homogeneous film. After that, three to four distinct homogeneous films were adsorbed on top of each other within 10 s and an uneven, knotted structure developed with stalky projections on the outer surface. This heterogeneous adsorption pattern determined the structure of the pellicle surface for at least 2 h.
