Features & Benefits

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 Uni-Etch w/BAC make etching easier?
Uni-Etch w/BAC’s blue 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 Uni-Etch 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 Uni-Etch w/BAC’s thixotropic viscosity significant?
BISCO’s semi-gel etchants (i.e., Uni-Etch 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 Uni-Etch 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.
