QRT-PCR results. A SMU_651c, SMU_652c, and SMU_653c were significantly up-regulated after adding copper ions (P < 0.05). B CopA was up-regulated after adding copper ions in both S. mutans mono biofilm and S. mutans–V. parvula dual biofilm (P < 0.05). CopY and copZ were up-regulated in the presence of 250 µM copper ions in S. mutans mono biofilm (P < 0.05)
