: a thin skin or film: such as. a : an outer membrane of some protozoans (such as euglenoids or paramecia) b : a film that reflects a part of the light falling upon it and transmits the rest and that is used for dividing a beam of light (as in a photographic device)

What is the acquired pellicle?

The acquired pellicle is a biofilm, free of bacteria, covering oral hard and soft tissues. It is composed of mucins, glycoproteins and proteins, among which are several enzymes. This review summarizes the present state of research on enzymes and their functions in the dental pellicle.

How do I get rid of acquired pellicle?

While chemical cleaning agents like peroxide are able to bleach stains from an intact pellicle, prophy pastes actually remove the pellicle. In order to restore its natural level of protection, the saliva generates a new, fresh pellicle within just a few short hours.
