The purpose of acid etch in dentistry is to prepare the enamel or dentin surface for bonding. Acid etching involves applying a mild acid to the tooth surface, which creates microscopic roughness. This roughened surface increases the surface area for adhesion, allowing bonding agents to create a stronger bond with the tooth structure. Etching is a crucial step especially when placing composite restorations or seals, as it enhances the effectiveness of the bonding agent applied subsequently. This process ensures that dental materials adhere properly and can function effectively within the oral environment.
