FIG. 6.

Representative histology slides stained with modified Gomori's trichrome for each treatment group. Each section is cut through the center axis of one defect site. Upper images show the entire defect at low power (0.31×). Lower images show one representative high-power field (10×). Yellow boxes indicate where the higher magnification images in the lower panel are coming from. Robust bone formation was observed in all treatments with little inflammation and no evidence of infection in any defect site.
