Figure 2

Experimental group at 4 weeks observational period (A,B) two successive images from one section revealing the formation of regenerative bone in wide areas of the defect with the formation of PDL fibers spanning the regions between the roots and the forming bone (insets), H&E, 40×. (C) Higher magnification of the two insets reveals the formation of PDL thin and irregular fibers spanning the distances between the roots and the forming bone. Note the homogeneous fiber patches (arrows) and the blood vessels among the regenerating irregular fibers (BV), H&E, 100×. (D) Formation of sheets of fibrous tissue between forming trabeculae and connecting them. These bone trabeculae consist partly of woven bone (circles), H&E, 100×. (E) Remodeling of the regenerating bone adjacent to the forming PDL (arrows), H&E, 100×. (F) Bone formation in close association with circular aggregates of β-TCP with accompanying rich blood supply (arrows), Trichrome stain, 100×. (G) Osteoblasts are arranged at the regenerating alveolar bone side and separated by the inserting fibers of the regenerating PDL, Trichrome stain, original magnification: 400×. (H) Cementoblasts are arranged in lines propagating perpendicular and in a radiating manner towards cementum and separated by inserting PDL fibers, Trichrome stain, 400×.
