Figure 5

Control group at 8 weeks observational period (A) Prevalence of bone formation at the sides and coronal parts of the defect. Some remanent of β-TCP particles is seen in the areas devoid of bone formation (thin arrows). PDL fibers are seen along one side of the regenerating defect, H&E, 40×. (B) Part of the regenerating defect just apical to the level of the thick arrow in the previous figure revealing part of the formed bone and aggregates of β-TCP between it and the PDL, H&E, original magnification 100×. (C) Disorganized PDL fibers and cells with the appearance of a fiber bundle exhibiting disorganized thickness and course towards the forming bone (arrow), H&E, 400×. (D) interrupted thin PDL fibers and disorganized orientation of the fibroblast cells, Note the inconsistent fiber insertion in cementum H&E, 400×. (E) Irregularly organized fibers and osteoblasts at the border of the formed bone and between the inserting fibers (arrows), Trichrome stain, 400×. (F) Irregularly organized cementoblasts adjacent to cementum, Trichrome stain, 400×.
