What is another name for etch used in dental procedures?

In dental procedures, etch is commonly referred to as "conditioner." This term reflects its function in preparing the tooth surface for bonding. Etching, typically done with phosphoric acid, removes the smear layer and creates micro-roughness on the enamel or dentin, increasing surface area for better adhesion of restorative materials. The conditioner enhances the bond between the tooth structure and the adhesive material, ensuring a strong and durable attachment for fillings, crowns, or other dental appliances.

While adhesive, primer, and filler are important materials in dentistry, they serve different purposes. Adhesives are substances that bond the restorative material to the tooth structure, while primers often enhance the penetration of adhesives, especially in dentin bonding. Fillers refer to materials that fill cavities or space in restorative procedures, but do not serve the primary function of preparing the tooth surface in the same way that a conditioner does.
