TABLE 2.
Comparisons of the differences in change level of distal buccal (DB), MD, distal lingual (DL) and bone level (BL) among the three groups (M(P25, P75)).
| Control group (n = 11) | Laser group (n = 10) | Concentrated growth factor (CGF) group (n = 10) | Sum (n = 31) | H | p | ||
|---|---|---|---|---|---|---|---|
| DB change level | Day 30 | 0 (−1, 0) | 1 (−0.25, 1) | 1 (0.75, 2)b | 1 (0, 1) | 11.544 | 0.003* |
| Day 90 | 1 (0, 1) | 1 (1, 2) | 1.5 (1, 2.25)b | 1 (1, 2) | 11.224 | 0.004* | |
| MD change level | Day 30 | 0 (0, 1) | 0 (0, 1) | 1 (0, 1) | 0 (0, 1) | 2.502 | 0.286 |
| Day 90 | 0 (0, 1) | 1 (0, 2) | 1 (0, 2) | 1 (0, 1) | 3.927 | 0.140 | |
| DL change level | Day 30 | 0 (−1, 1) | 1 (0, 1) | 0.5 (0, 1.25) | 1 (0, 1) | 4.348 | 0.114 |
| Day 90 | 1 (0, 1) | 0.5 (0, 1) | 1 (0, 2) | 1 (0, 1) | 2.224 | 0.329 | |
| BL change level | Day 30 | −0.5 (−1, 0.5) | 0.5 (−0.625, 1.125) | 1 (0.5, 1.625)b | 0.5 (−0.5, 1) | 8.101 | 0.017* |
| Day 90 | 0 (−0.5, 1.5) | 1.75 (0.875, 2.25) | 2.25 (1.375, 3)b | 1.5 (0, 2.5) | 8.417 | 0.015* |
Note: * indicates p ≤ 0.05, suggesting a statistical difference. b represents the CGF group, and the control group has a statistical difference. MD change, DL change, DB change and bone height change were subtracted from baseline at each time point.
