Etch-37 is a 37% semi-gel phosphoric acid etchant available with Benzalkonium Chloride (BAC) and designed for etching tooth structure prior to bonding.
Etch-37 w/BAC is a 37% phosphoric acid semi-gel etchant that is effective at quickly etching enamel and dentin. Etch-37 w/BAC is polymer-thickened and effectively removes the smear layer, etches and demineralizes enamel and dentin. It is easily manipulated into small areas such as endodontically treated root canals and undercuts. This makes it more versatile than some thicker gel etchants for etching all restorative surfaces. Published research proves that BISCO etchants produce higher bond strengths to (wet or dry) dentin1 and enamel.
Features & Benefits
Contains BAC: Available with benzalkonium chloride (BAC), an antimicrobial agent. In-vitro research shows it is effective against Actinomyces viscosus.
Blue Color: Blue in color for easy visualization and contrast.
Easy Wash Off: Etchant rinses away cleanly and quickly, leaving no residue to interfere with bonding.
Thixotropic: BISCO semi-gel etchants utilize a polymer to create thixotropic properties and enhance handling characteristics.
Unparalleled Bond: Creates microretentive surfaces that are necessary for successful bonding. Published research proves that BISCO etchants produce higher bond strengths to (wet or dry) dentin1 and enamel.
Benzalkonium chloride (BAC) is an antimicrobial agent. When BAC is present, research confirms the development of residual bacterial inhibition zones of up to 7mm when challenged with Actinomyces viscosus.1
NOTE: The inclusion of benzalkonium chloride has not been shown to correlate with a reduction in secondary decay in patients. In-vivo clinical studies to evaluate the effects of benzalkonium chloride on oral bacteria or caries have not been performed.
Etch-37 w/BAC’sblue color allows for easy identification and contrast where deep color differentiation is important. The vibrant color assists clinicians in being able to see the product during placement and removal procedures.
BISCO’s semi-gel etchants (i.e. Etch-37 w/BAC) utilize a polymer to create thixotropic properties and enhance handling characteristics. It is more versatile than thicker gel etchants because it can be easily manipulated into small areas such as endodontically treated root canals and undercuts.
It is recommended to use the tips that arrive with the product, which have been tested for optimal dispensing. The 25-gauge tip should be used with the 1g syringe, and the 22-gauge tips should be used with the 5g syringe.
