| Treatment | |||||
|---|---|---|---|---|---|
| Parameter | Control | VitD(−) | ZOL | VitD(−)/ZOL | |
| Empty osteocyte lacunae of buccal alveolar bone (%) | Unwounded side | 6.7 ± 1.5 | 6.2 ± 2.1 | 7.3 ± 3.2 | 7.4 ± 1.3 |
| Tooth ext. side | 7.2 ± 1.2 | 6.9 ± 2.5 | 9.2 ± 4.9 | 11.3 ± 1.4 *** | |
| Occurrence of bone exposure (%) | Unwounded side | 0 | 0 | 0 | 0 |
