What is the meaning of Polyvinyl Alcohol?
Polyvinyl Alcohol is widely used term in Dental Materials.
Polyvinyl Alcohol (PVA) is a synthetic water-soluble polymer that finds extensive use in dental materials. It is derived from the polymerization of vinyl acetate, followed by partial hydrolysis to convert it into PVA.
In dental materials, PVA is primarily used as a binder or dispersing agent due to its excellent adhesion properties. It is commonly used in dental cements, impression materials, and restorative materials to improve their mechanical properties and handling characteristics.
PVA in dental materials provides several benefits. It enhances the flow and workability of dental cements and composites, allowing for easier manipulation during the restorative procedures. It also improves the wetting properties of these materials, ensuring better adhesion to the tooth structure.
One of the notable properties of PVA is its ability to form a thin film when dried, making it useful as a protective coating for dental materials. This coating prevents the uptake of water, saliva, and other oral fluids, thus enhancing the durability and lifespan of the restorations.
Furthermore, PVA is biocompatible and non-toxic, making it safe for use in dental applications. It does not cause any adverse reactions or allergies in patients when used appropriately.
Overall, Polyvinyl Alcohol is a valuable component of dental materials, contributing to their handling characteristics, adhesion properties, and durability. Its versatility and biocompatibility make it a widely used polymer in the field of dentistry.
