Product Description
Ultra Etch Acid Etchant by Ultradent is a high-performance 35% phosphoric acid gel designed to create optimal bonding surfaces on enamel and dentin. Its advanced formulation delivers precise etching, controlled depth, and consistent clinical results in restorative and adhesive procedures.
The etchant features a self-limiting chemistry, achieving an average etch depth of approximately 1.9 µm within 15 seconds. As a result, it prevents over-etching while producing an ideal micro-retentive surface that enhances adhesive penetration and bond strength. This controlled action also helps reduce post-operative sensitivity.
Moreover, its ideal viscosity ensures accurate placement without running on vertical surfaces. While the gel remains stable during application, it still penetrates deeply into fissures and occlusal surfaces through capillary action. Consequently, clinicians achieve uniform etching even in hard-to-reach areas.
In addition, Ultra Etch rinses cleanly without leaving residue, ensuring a contaminant-free surface for bonding. This improves adhesion reliability and supports long-term restoration success.
The syringe delivery system allows precise control and minimal waste, especially when used with compatible delivery tips. Therefore, it is an essential product for clinicians seeking efficiency, consistency, and superior bonding performance.
Total Control In Handling
Ultra-Etch etchant is a 35% phosphoric acid solution for use on dentin and enamel to create ideal bonding surfaces. Ultra-Etch etchant is self-limiting in its depth of etch, creating an etch pattern that adhesives can penetrate for increased bond strength and reduced sensitivity. Combined with an ideal viscosity that facilitates precise placement, this unique self-limiting chemistry results in an optimal surface to receive resin.
Optimal Viscosity
Ultra-Etch etchant is uniquely formulated with ideal viscosity. Though it is viscous, it can penetrate into the smallest fissures or occlusal surfaces due to physical and chemical properties that promote capillary action.
Yet, its ideal viscosity maintains a layer thick enough to prevent it from running on vertical surfaces or drying prematurely.
Self-limiting
Ultra-Etch etchant is proven to be uniquely self-limiting in its depth of etch, with an average depth of 1.9 μm with 15-second etch.
In a study comparing etchants, liquid phosphoric acid (37%) showed an average depth of 5.0 μm at 20 seconds, and a competing “polymer-thickened” etchant showed an average depth of 4.8 μm.
Acids with this greater depth of etch go beyond the optimum level and increase the potential for incomplete resin impregnation.
Industry Leader for More Than 30 Years
Ultra-Etch etchant is perfect for any restoration in any part of the mouth.
It has been named a “Can’t Live Without” product, called “Tried & True,” and has been a Reality’s Choice 5-star award winner6 for years on end.
Ultra Etch Acid Etchant Clinicals
Ideal for Etching Dentin and EnamelClinical experience and FE-SEM evaluations 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.
