Global Phosphoric Acid Etching Gel Competitive Landscape Professional Research Report 2025
Phosphoric acid etching gel is a dental material used primarily to prepare tooth surfaces—especially enamel and dentin—for bonding procedures by creating micro-roughness that enhances adhesion. Typically containing 30–40% phosphoric acid in a gel base, it is easy to control and apply precisely to targeted areas without flowing uncontrollably. The gel removes the smear layer and opens up enamel rods or dentinal tubules, allowing for stronger mechanical interlocking with restorative materials such as composite resins or sealants. Its vivid color (often blue) ensures clear visibility during application and rinsing.
