Table 1 The experimental group (group B) showed a statistically significant increase in the mean value of fraction of bone regeneration (%) (FBR_B = 33.84%) relative to the control group (group A) (FBR_A = 15.92%) (P = 0.000 < < 0.001). Group B also showed a statistically significant increase in the mean value of cell density (CD; osteocytes/mm2) (CD_B = 519.56 Ost/mm2) relative to the group A (CD_A = 414.48 Ost/mm2) (P = 0.004).
