Acquired pellicle

Acquired Pellicle is a protein film that forms on the surface of teeth immediately after cleaning. It is a product of the selective binding of glycoproteins from saliva that adsorb to the tooth surface. This film is fully formed within an hour after exposure to the oral environment.

Formation

The formation of the acquired pellicle is a selective process whereby specific molecules in the saliva bind to the tooth surface. The process begins immediately after tooth cleaning and is fully formed within an hour. The acquired pellicle is a protective barrier that protects the tooth from acidic attacks and acts as a reservoir for calcium ions.

Composition

The acquired pellicle is composed of a variety of salivary proteins, glycoproteins, and lipids. The exact composition can vary depending on the individual's diet, oral hygiene, and overall health. The most abundant proteins in the acquired pellicle are amylase, lysozyme, and proline-rich proteins.

Role in Dental Health

The acquired pellicle plays a crucial role in dental health. It acts as a protective barrier against acid attacks from the diet and bacterial metabolism. It also acts as a reservoir for calcium ions, which can help to remineralize the tooth surface. However, the acquired pellicle can also serve as a binding site for bacteria, leading to the formation of dental plaque and potentially contributing to the development of dental caries and periodontal disease.

Role in Dental Disease

While the acquired pellicle plays a protective role, it can also contribute to dental disease. The pellicle provides a surface for bacteria to adhere to, leading to the formation of dental plaque. This can contribute to the development of dental caries and periodontal disease. Additionally, the pellicle can become stained from substances such as coffee, tea, and tobacco, leading to tooth discoloration.

Prevention and Treatment

Maintaining good oral hygiene is crucial in managing the acquired pellicle. Regular tooth brushing and flossing can help to remove the pellicle and prevent the build-up of plaque. Additionally, regular dental check-ups can help to monitor the health of the teeth and gums and provide early treatment for any issues that may arise.
