Etch-37 w/BAC: 37% Semi-gel Phosphoric Acid

Etch-37 is a 37% semi-gel phosphoric acid etchant containing Benzalkonium Chloride (BAC), formulated for etching tooth structure prior to bonding.

37% Phosphoric Acid Etchant with Benzalkonium Chloride
Etch-37 w/BAC is a 37% phosphoric acid semi-gel etchant that effectively etches enamel and dentin. It is polymer-thickened and efficiently removes the smear layer while etching and demineralizing enamel and dentin. The material is easily manipulated into confined areas such as endodontically treated root canals and undercuts, offering greater versatility compared to thicker gel etchants for etching all restorative surfaces. Published research indicates that BISCO etchants produce higher bond strengths to both wet and dry dentin¹ and enamel.

• Rinses away cleanly and rapidly, leaving no residue to interfere with bonding

• Blue in color for easy visualization and contrast

• Creates microretentive surface characteristics essential for successful bonding

• New bulk syringe delivery system available

• Contains benzalkonium chloride (BAC), an antimicrobial agent. In vitro research demonstrates effectiveness against Actinomyces viscosus²

NOTE: Inclusion of BAC has not been shown to correlate with a reduction in secondary decay in patients. In vivo clinical studies evaluating the effects of BAC on oral bacteria or caries have not been performed.
