Table 1.

Percentage of new bone formation in each group in the two experimental periods (14 and 42 days). BMG—defects filled with HA/β-TCP covered by a bovine biological membrane; BFMG defects filled with HA/β-TCP and heterologous fibrin biopolymer covered with bovine biological membrane; BFMLG defects filled with HA/β-TCP and heterologous fibrin biopolymer covered with bovine biological membrane and PBMT.

	14 Days	42 Days	p Value
BMG	4.51 ± 0.44aA	7.11 ± 0.44bA	p < 0.0001
BFMG	7.35 ± 0.66aB	9.41 ± 0,84bB	p = 0.0026
BFMLG	10.12 ± 0.67aC	13.85 ± 0.54bC	p < 0.0001

Different lowercase letters (line) indicate a significant difference in each group in the two periods (unpaired t-test). Different capital letters (column) indicate a significant difference in the same period between groups (ANOVA and Tukey). Values defined as the mean ± standard deviation (p < 0.05).
