Ultra-Etch etchant 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 etchant 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 etchant’s unique self-limiting chemistry creates an optimal surface to receive resin.2 Though Ultra-Etch etchant 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.
- Penetrates smallest fissures but won’t migrate on a vertical surface
- Increases bond strength and reduces sensitivity
- Places precisely and rinses clearly
- Rinses cleanly—leaves no residue
Indications for Use
Ultra-Etch etchant can be placed in any location, including lingual approaches to Class III restorations. It works nicely for etching before bonding composites, sealants, or adhesives.
Ultra-Etch etchant 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.
Ultra-Etch etchant 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 etchant is easy to see, so it helps in precise placement and complete removal.
The Industry Leader for Over 20 Years
Ultra-Etch etchant has been called a “Can’t Live Without” product,3 it’s been called “Tried & True,”4 and it’s been a 5-star award winner5 for years on end. Simply put, Ultra-Etch etchant is the best.
Ideal for Etching Dentin and Enamel
Clinical experience and FE-SEM evaluations2 show that 20 seconds etch time on both dentin and enamel provides optimal conditioning of both tissues. Air/water rinse. Blot excess water off, leaving surface visibly wet.
Self-Limiting Chemistry Creates Optimal Surface
With an average depth of 1.9μm with a 15-second etch, Ultra-Etch etchant stops etching at the ideal depth.
