Micro-CT and histomorphometric results for DBB group. a 2D-Micro-CT view: the images show small and irregular DBB particles (blue arrow) surrounded by new bone (yellow arrow) at 30 days. Between 30 and 180 days, the spaces were filled by bone. b Histologic view: at 30 days note that the bone formation occurred on the surface of the DBB (area surrounded by black dotted line), the spaces were filled by connective tissue (CT) rich in cells and blood vessels. At 60 days, the spaces between the particles were occupied by a large amount of bone (yellow arrow) and bone marrow (BM) replacing connective tissue. At 180 days, lamellar bone tissue and some areas of osteoclastic reabsorption in both biomaterial and bone. HE; 10×, c) Percentage of each constituent: graphs of evolution of M% (C1), CT% (C2), NB% (C3), and BM% (C4) in MSA of DBB/clot and DBB/PRP. Different letters p < 0.05 among periods per group
