Understanding the Acquired Pellicle

What is the Acquired Pellicle?

The acquired pellicle is a thin, protein-rich film that forms on the surface of teeth. It is composed of a mixture of proteins, including salivary proteins, bacterial proteins, and other organic compounds. The pellicle is formed when saliva comes into contact with the tooth surface, and it can be easily removed during coronal polishing.

Formation of the Acquired Pellicle

The acquired pellicle forms quickly, usually within minutes of exposure to saliva. It is a dynamic process that involves the interaction of saliva, bacteria, and the tooth surface. The pellicle is thought to play a role in the development of dental plaque and the initiation of tooth decay.

Composition of the Acquired Pellicle

The acquired pellicle is composed of a mixture of proteins, including:

Salivary proteins: These proteins are produced by the salivary glands and play a role in the formation of the pellicle.
Bacterial proteins: These proteins are produced by bacteria that adhere to the tooth surface and contribute to the formation of the pellicle.
Other organic compounds: These compounds include sugars, amino acids, and other molecules that are present in saliva.

Removal of the Acquired Pellicle

The acquired pellicle can be easily removed during coronal polishing. Coronal polishing is a dental procedure that involves the removal of plaque and stains from the surface of teeth. The pellicle is removed using a combination of mechanical and chemical means, including:

Mechanical removal: This involves the use of a polishing instrument to remove the pellicle from the tooth surface.
Chemical removal: This involves the use of a chemical solution to dissolve and remove the pellicle.

Importance of the Acquired Pellicle

The acquired pellicle plays a role in the development of dental plaque and the initiation of tooth decay. It is also thought to contribute to the formation of dental stains and the development of periodontal disease.

Q&A

Q: What is the acquired pellicle? A: The acquired pellicle is a thin, protein-rich film that forms on the surface of teeth shortly after brushing or exposure to saliva.

Q: How is the acquired pellicle formed? A: The acquired pellicle is formed when saliva comes into contact with the tooth surface, and it is composed of a mixture of proteins, including salivary proteins, bacterial proteins, and other organic compounds.

Q: Can the acquired pellicle be removed? A: Yes, the acquired pellicle can be easily removed during coronal polishing.

Q: What is the importance of the acquired pellicle? A: The acquired pellicle plays a role in the development of dental plaque and the initiation of tooth decay, and it is also thought to contribute to the formation of dental stains and the development of periodontal disease.

Q: How often should the acquired pellicle be removed? A: The acquired pellicle should be removed regularly, ideally during routine dental cleanings and check-ups.

Q: Can the acquired pellicle be prevented? A: While it is not possible to completely prevent the formation of the acquired pellicle, good oral hygiene practices, such as regular brushing and flossing, can help to reduce its formation.

Conclusion

The acquired pellicle is a thin, protein-rich film that forms on the surface of teeth shortly after brushing or exposure to saliva. It is a natural occurrence that can affect the overall health and appearance of teeth. In this article, we have explored the composition, formation, and removal of the acquired pellicle, as well as its importance and prevention. By understanding the acquired pellicle, we can take steps to maintain good oral health and prevent the development of dental problems.
