Dental pellicle

It is a protein film that forms on the surface enamel by selective binding of glycoproteins from saliva. It is protective to the tooth from the acids produced by oral microorganisms after consuming the available carbohydrates.

It is also a means for the microorganisms to attach to the tooth and form what is called Dental plaque.

The salivary pellicle is a layer of negatively charged salivary glycoproteins that adhere to the enamel of tooth surfaces, allowing cariogenic bacteria to adhere to the tooth surface.
