32% Phosphoric Acid Etchants with Benzalkonium Chloride
(BAC)
BlueAcid is 32% semi-gel phosphoric acid etchants with BAC(Benzalkonium Choloride).
They are ideal for etching tooth structure prior to bonding, and are specifically formulated to be easily applied to larger surface areas and rinse cleanly with no residue.
In addition, they are easily manipulated into small areas such as endodontically treated root canals and undercuts.
This makes them more versatile than thicker gel etchants for etching all restorative surfaces.
Note the presence of silica, used as filler, on the etched, rinsed surface. Imperceptible to the naked eye, the remaining debris can impede the flow of primer over the dentin surface and into the dentinal tubules. This can compromise surface wetting and bond strength.
Amco etchants utilizze a polymer to create thixotropic properties and enhance handling characteristics. Furthermore, it leaveds no residue, rinsing away completely.
In-Vitro research confirms the development of residual bacterial inhibition zones of up to 7mm, when challenged with Actinomyces viscosus T14V. This bacterium is implicated in periodontal disease and root caries and has as much significance as Streptococcus sobrinus 6715. The standard inoculum will be in broth culture with approximately 108 CFU/ml.²
ㆍRinses away cleanly and quickly leaving no residue to interfere with bonding.
ㆍBlue in color for easy visualization and contrast.
ㆍCreates microretentive surface characteristics that are necessary for successful bonding.
ㆍContains benzalkonium chloride (BAC), an antimicrobial agent. In-vitro research shows it is effective against Actionomyces 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.
