Largent Health has announced the U.S. availability of FiteBac Antimicrobial Cavity Cleanser, with 2% K21. Cavity cleansers are used for cleansing and moistening/re-wetting of prepared dental surfaces prior to completion of tooth restoration. The company included in their FDA application what it describes as compelling data supporting antimicrobial activity that reduces dentally relevant microbes.1-3

FiteBac technology exemplifies the marriage of antimicrobial technology to material science, enabling the manufacture of materials offering sustained, non-leaching antimicrobial protection.

FiteBac Antimicrobial Cavity Cleanser, containing the patented antimicrobial K21, is intended to become part of the restoration/dentin interface by copolymerizing with the dental adhesive. Research shows FiteBac Cavity Cleanser can not only help remove debris in preparations, but also help reduce the presence of pathogens within the prepared tooth structure, and also penetrate exposed dentin tubules, allowing restorative adhesives to tightly bind to the prepared dentin surface.
