Representative live/dead images of 3-day multi-species periodontal biofilms on the four adhesive resins: (A) PEHB control, (B) PEHB+5MPC, (C) PEHB+5DMAHDM, and (D) 5DMAHDM+5MPC. Live bacteria were stained green. Dead bacteria were stained red. Resins without DMAHDM had primarily live bacteria. 5DMAHDM+5MPC had much less bacterial adhesion, and the biofilms consisted of primarily dead bacteria.
