The dental pellicle, or acquired pellicle, is a protein film that forms on the surface enamel, dentin, artificial crowns, and bridges by selective binding of glycoproteins from saliva that prevents continuous deposition of salivary calcium phosphate. It forms in seconds after a tooth is cleaned, or after chewing.
An acquired pellicle is a layer of saliva that is composed of mainly glycoproteins and forms shortly after cleaning of the teeth or exposure of new teeth. [7] Bacteria then attach to the pellicle layer, form micro-colonies, and mature on the tooth, which can result in oral diseases.

Crombie often saw the birds form patterns and abstract shapes, their varying densities appearing like the subtle gradations of paint strokes. The photographer became convinced that, with enough ...
Formation of an acquired pellicle: involves selective absorption of salivary and GCF molecules through an electrostatic affinity with hydroxyapatite. [20] Bacterial transportation: bacteria will readily adhere to the acquired pellicle through adhesins, proteins and enzymes within one to two hours. [20]
