Application of D-Amino Acids as Biofilm Dispersing Agent in Dental Unit Waterlines

Figure 4

Optical density at 600 nm of dispersed biofilms in flushing water collected after the DUWLs of DCUs were incubated with distilled water (control), D-amino acids mixture (D-amino acids, 10 mM each), or 0.1 M HCl for 5 days. The DUWLs were flushed every other day for 10 days, and the flushing water was collected to measure the OD⁶⁰⁰ of dispersed biofilms. Statistically different at .
