The responses of P. gingivalis (Pg) to the Mg-Cu alloy and Mg and β-TCP extracts: (a) bacterial concentration; (b) live bacterial colonies; (c) optical images of the bacterial colonies in nutrition agar plates and the responses of A. actinomycetemcomitans (Aa) to the Mg-Cu alloy and Mg and β-TCP extracts; (d) bacterial concentration; (e) live bacterial colonies; (f) optical images of the bacterial colonies in nutrition agar plates. refers to a significant difference between Mg-Cu alloy groups (Mg-0.1Cu, Mg-0.2Cu, and Mg-0.3Cu) and the BHI broth and β-TCP groups. # refers to a significant difference between Mg-Cu alloy groups and the Mg group (, ).
