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,1 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.
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.
Ultra-Etch etchant's ideal viscosity, along with the use of the Blue Micro™ or Inspiral™ Brush tip, facilitates precise placement and superior control. Ultra-Etch etchant also rinses clearly and cleanly, leaving no residue.
Ultra-Etch etchant is proven to be uniquely self-limiting in its depth of etch, with an average depth of 1.9 ?m with 15-second etch. In a study comparing etchants, liquid phosphoric acid (37%) showed an average depth of 5.0 ?m at 20 seconds, and a competing “polymer-thickened” etchant showed an average depth of 4.8 ?m.2 Acids with this greater depth of etch go beyond the optimum level and increase the potential for incomplete resin impregnation.
