Product Details
Ultra-Etch is a 35% phosphoric acid solution. It features ideal viscosity, which, along with the use of the Blue Micro® or Inspiral® Brush tip, facilitates precision placement and superior control. Ultra-Etch is self-limiting in its depth of etch (average depth of 1.9μm with 15-second etch),1 creating an etch pattern that adhesives can penetrate for increased bond strength and reduced sensitivity. Studies demonstrate that Ultra-Etch’s unique self-limiting chemistry creates an optimal surface to receive resin.2 Though Ultra-Etch is viscous, it can penetrate into the smallest fissures or occlusal surfaces due to physical and chemical properties that promote capillary action. Its ideal viscosity maintains a layer thick enough to prevent premature drying.
Indications for Use
Ultra-Etch can be placed in any location, including lingual approaches to Class III restorations. It works nicely for etching before bonding composites, sealants, or adhesives.

Optimal Viscosity
Ultra-Etch is uniquely formulated with a viscosity that is thin enough to penetrate the smallest fissures but thick enough to prevent it from running on vertical surfaces, so it’s perfect for any restoration in any part of the mouth.
Self-Limiting
Ultra-Etch is proven to be uniquely self-limiting in its depth of etch, with an average depth of 1.9μm using a 15-second etch. In a study comparing etchants, liquid phosphoric acid (37%) showed an average of 5.0μm at 20 seconds, and a competing “polymer-thickened” etchant a 4.8μm depth.2 Acids with this greater depth of etch go beyond the optimum level and increase the potential for incomplete resin impregnation.
Easy Placement and Removal
The signature blue color of Ultra-Etch is easy to see, so it helps in precise placement and complete removal.
