Description

37% Phosphoric Acid Etchant with Benzalkonium Chloride
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.

  • Rinses away cleanly and quickly leaving no residue to interfere with bonding
  • Blue in color for easy visualization and contrast
  • Creates microretentive surface characteristics that are necessary for successful bonding.
  • New bulk syringe delivery system available
  • Contains benzalkonium chloride (BAC), an antimicrobial agent. In-vitro research shows it is effective 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 to evaluate the effects of BAC on oral bacteria or caries have not been performed.

What is BAC and what benefits does it provide?
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.

How does the “blue” color of Etch-37 w/BAC make etching easier?
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.

How long should I etch or clean my restorations with Etch-37 w/BAC?

  • Dentin and enamel should be etched for 15 seconds.
  • If using phosphoric acid as a cleaning agent on dental restorative materials: 30 seconds.

Why is Etch-37 w/BAC’s thixotropic viscosity significant?
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.

Can Etch-37 w/BAC be used with any other tips than the 25-gauge blue tips that are provided?
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.
