Fig. 4From: Ridge preservation applying a novel hydrogel for early angiogenesis and osteogenesis evaluation: an experimental study in canineEarly angiogenesis, osteogenesis and osteoclast activity characterization at the most central area within the socket. a. the blood vessels, woven bone and osteoclasts of the extracted socket at 2 weeks postoperation. Blue arrow indicates blood vessels; dotted line indicates the boundary of DBBM particles; ★ indicates woven bone. b. qualitative histometric analysis among all groups at 2 weeks postoperation. a: other groups vs Control (p < 0.05); b: other groups vs DBBM (p < 0.05); c: other groups vs DBBM+i-PRF (p < 0.05); d: other groups vs GNPs (p < 0.05); e: other groups vs GNPs+i-PRF (p < 0.05)Back to article page
