37% Phosphoric Acid Etchant for Reliable Dental Bonding

Spident FineEtch 37% is a semi-gel phosphoric acid etchant designed to prepare enamel and dentine before adhesive dental procedures. Containing 37% phosphoric acid (H₃PO₄), Spident FineEtch 37% effectively removes the smear layer and creates an ideal surface for bonding. As a result, clinicians can achieve stronger adhesion between the tooth structure and restorative materials.

The controlled semi-gel consistency provides excellent handling while helping prevent unnecessary material movement. Therefore, clinicians can apply the etchant accurately to the treatment area without compromising visibility or control. In addition, the blue colour makes placement easy to see and allows for confident application during restorative procedures.

Consistent etching for predictable results

Spident FineEtch 37% delivers effective enamel and dentine conditioning by removing the smear layer before bonding. This process increases the surface energy of the tooth and promotes stronger adhesion between the tooth and composite restorations, sealants, or adhesive systems. Consequently, clinicians can achieve more reliable and predictable restorative outcomes.

The advanced formulation also contains biocompatible polymeric materials that support smooth application and consistent performance. Meanwhile, the excellent viscosity keeps the material where it is placed, allowing precise application without excessive flow.

After etching, the material rinses away completely with a water spray, leaving no residue behind. As a result, the prepared tooth surface is clean and ready for the next stage of the bonding procedure.

Clinical applications

Spident FineEtch 37% is suitable for a wide range of restorative and preventive dental procedures, including:

• Enamel and dentine etching before adhesive restorations.
• Pretreatment before composite resin placement.
• Pretreatment before pit and fissure sealants.
• Removal of the smear layer to improve bonding performance.
• Surface preparation for reliable adhesive procedures.
