Antibacterial effect of Ti, Zr, and CrPEEK samples against E. coli (nm) and S. aureus (nm) strains.
| Samples | E. coli (nm) | S. aureus (nm) |
|---|---|---|
| Penicilin 10 µL | 11.5 ± 1.4 | 25 ± 1.8 |
| AmphotericinB 10µL | 10.6 ± 0.7 | 21.7 ± 1.0 |
| Ti | 18.4 ± 0.7 | 37 ± 1.9 * |
| Zr | 13.9 ± 1.1 | 37.6 ± 2.1 * |
| CrPEEK | 15.8 ± 2.1 | 45.8 ± 3.5 * |
| Ti-NaOH | ND | ND |
| Zr-NaOH | ND | 15.9 ± 1.1 |
| CrPEEK-NaOH | 14.4 ± 1.3 | 14.1 ± 0.8 |
ND—not detected. Ti—titanium; Zr—zirconia; CrPEEK—ceramic-reinforced PEEK; Ti-NaOH—coated Titanium; Zr-NaOH—coated zirconium; CrPEEK-NaOH—coated ceramic-reinforced PEEK. Values are mean + standard deviation, and * denotes statistical significance, p < 0.05.
