Fig. (4) Antimicrobial treatment efficacy against biofilms formed on DBR disc surfaces and planktonic cells. The biofilms and planktonic cells of F. nucleatum (A) and K. pneumoniae (B) were treated with denture cleansers as described in the Materials and Methods. The viability of biofilms after treatment was assessed by colony-forming units (CFU) on agar plates. Standard error of three replicates is presented.
