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.
It can be found in various products which include chewing gums and lozenges. Xylitol has been found to reduce mutans streptococci in plaque and saliva and reduce the binding of these to the acquired enamel pellicle. [10] This in turn leads to less adherent plaque and a decrease in acid production. [10]
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.
From ancient history to the modern day, the clitoris has been discredited, dismissed and deleted -- and women's pleasure has often been left out of the conversation entirely. Now, an underground art movement led by artist Sophia Wallace is emerging across the globe to challenge the lies, question the myths and rewrite the rules around sex and the female body.
An acquired characteristic is a non-heritable change in a function or structure of a living organism caused after birth by disease, injury, accident, deliberate modification, variation, repeated use, disuse, misuse, or other environmental influence. Acquired traits are synonymous with acquired characteristics.
Pellicle (biology), a thin layer supporting the cell membrane in various protozoa; Pellicle mirror, a thin plastic membrane which may be used as a beam splitter or protective cover in optical systems; Pellicle (dental), the thin layer of salivary glycoproteins deposited on the teeth of many species through normal biologic processes
The development of biofilm begins with pellicle formation. Pellicle is an acellular proteinaceous film which covers the teeth. Bacteria colonize on the teeth by adhering to the pellicle-coated surface. Over time, a mature biofilm is formed, creating a cariogenic environment on the tooth surface.
