In-vitro antibiofilm activity of chlorhexidine digluconate on polylactide-based and collagen-based membranes

摘要

Total cfu counts ( , ) of a 2-species “healthy” biofilm, and total cfu counts of a 6-species “periodontal” biofilm ( , and counts of ( , ) and ( , ) in “periodontal” biofilm after dipping initially polylactide ( , , , ) and collagen ( , , , ) membranes into 0.06 and 0.12% chlorhexidine digluconate solution (CHX0.06 and CHX0.12) and culturing the biofilms for 2 h and 8 h. Presented are median and 10, 25, 75 and 90 percentiles. *  p
