F-type ATP synthase activity of P. gingivalis (A) and F. nucleatum (C) cultured on SLA and SLA-Ta surfaces for 24hrs. ATP levels of P. gingivalis (B) and F. nucleatum (D) cultured on SLA and SLA-Ta surfaces for 24hrs. *P<0.5, significantly different from the control SLA group. **P<0.01, significantly different from the control SLA group.
