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.2
