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.
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]
At some point in the mid-1980s, a pony-tailed upstate New York environmental activist named Jay Westerveld picked up a card in a South Pacific hotel room and read the following: "Save Our Planet ...
Plaque and calculus deposits are a major etiological factor in the development and progression of oral disease. An important part of the scope of practice of a dental hygienist is the removal of plaque and calculus deposits. This is achieved through the use of specifically designed instruments for debridement of tooth surfaces.
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.
Coloured compounds from these sources are adsorbed into acquired dental pellicle or directly onto the surface of the tooth causing a stain to appear. [ 7 ] Dental plaque : Dental plaque is a clear biofilm of bacteria that naturally forms in the mouth, particularly along the gumline , and it occurs due to the normal development and defences of ...
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.
