Table of volume density of new bone formation (%).

	BM + PBMT	BM + HFB	BM + HFB + PBMT
14 days	22.20 ± 1.77 Aab	20.00 ± 1.87 Ab	26.40 ± 1.03 Aa
42 days	33.20 ± 2.18 Bab	31.60 ± 1.33 Bb	38.20 ± 1.59 Ba

Different uppercase letters (comparison in columns, 14 vs. 42 days) indicate a statistically significant difference. Different lowercase letters (line comparison, BM + PBMT vs. BM + HFB vs. BM + HFB + PBMT in each period, 14 or 42 days) indicate a statistically significant difference. Student’s t and Tukey’s test, respectively, both at 5% probability.
