The acquired pellicle, which is composed of a variety of host-derived molecules, coats the enamel surface within minutes after professional cleaning and is a source of receptors for primary colonisers of the plaque [4]--Streptococci spp., Actinomyces spp., Capnocytophaga spp., Eikenella spp., Haemophilus spp., and Veillonella spp.

Interspecies communication and periodontal disease

Although the acquired pellicle is permeable to small ions, it tends to act as a barrier to diffusion, and it reduces the possible mineral transportation between the tooth and the oral environment, thus promoting or interfering with the remineralization process.

The slabs on which human salivary pellicle was formed, were individually positioned in wells containing 2.0 ml of the inoculum and were incubated at 37[degrees]C, 10% C[O.sub.2] to allow bacterial adhesion on the acquired pellicle. All these procedures were carried out according to Koo et al.
