Surface roughness and water contact angle of bracket materials used in this study
| Surface characteristics | CR | SS | PL | HA | Significance | |
|---|---|---|---|---|---|---|
| Surface roughness (μm) | 0.61 ± 0.24 | 0.55 ± 0.20 | 0.85 ± 0.27 | 1.26 ± 0.13 | CR = SS < PL < HA | < 0.001 |
| Water contact angle (°) | 51.16 ± 26.06 | 85.39 ± 10.5 | 96.49 ± 7.89 | 42.69 ± 16.5 | CR = HA < SS < PL | < 0.001 |
Values are presented as mean ± standard deviation.
CR, monocrystalline alumina ceramic; SS, stainless steel; PL, polycarbonate plastic; HA, hydroxyapatite.
