The mineral apposition rate between the two groups at each observation period (μm·d−1)
| Group (n=24) | Week 4 | Week 8 | Week 12 |
|---|---|---|---|
| SF group | 1.14±0.13 | 1.38±0.15 | 0.76±0.06 |
| MAO group | 1.35±0.10 | 1.45±0.20 | 0.93±0.07 |
| P-value | P < 0.05 | P < 0.05 | P < 0.05 |
The rate in the MAO group was greater than in the SF group and had statistical significance in each observation period (Student’s unpaired t-test). MAO microarc oxidation, SF smooth surface
