What is the meaning of Phosphoric Acid?
Phosphoric Acid is widely used term in Dental Materials.
Phosphoric acid in dental materials refers to a type of acid that is commonly used in dentistry for etching or preparing the tooth surface before applying various dental materials such as composite resin fillings or dental bonding agents.
Etching with phosphoric acid involves applying a diluted solution of phosphoric acid to the enamel or dentin surface of a tooth. This creates micro-porosities on the tooth surface, allowing for improved adhesion between the dental material and the tooth. The acid etching process helps create a rough surface, which in turn enhances the bonding and retention of the dental material to the tooth structure.
Phosphoric acid is typically applied for a short period of time and then rinsed off thoroughly to prevent any residual acid from affecting the oral tissues or causing further damage to the tooth structure. The use of phosphoric acid in dental materials is a common and effective technique for enhancing the longevity and durability of dental restorations.
