• FiteBac® K21 QAS, consists of four Silane Quaternary Ammonium structures
    covalently linked to a silane core
  • Studies have shown that K21 QAS demonstrates
    • Does not negatively impact adhesive bond strength to dentin (1,2)
    • Excellent antimicrobial activity (1,3)
    • Improves infiltration of adhesive monomers into acid etched dentin (1)
    • Inhibition of MMP-9 and Cathepsin-K (1,3)
  • Patent Protection until 2033
