1. Figure 6. Histological observations of specimens retrieved at 8 weeks after surgery (positive control group, A; negative control group, B; experimental group, C) (MT stain, original magnification 200×). (A) Connective tissue fibers of the periodontal ligament (PDL) were observed between the root surfaces and alveolar bone. (B) The root surfaces were fused with alveolar bone. Connective tissue fibers of the periodontal ligament could not be observed on root surface. (C) Loosely organized fibers of the newly formed PDL-like tissue were observed in spaces between root surfaces and alveolar bone. Ab, alveolar bone; De, dentin; Ce, cementum; Pd, periodontal ligament; nPd, newly formed periodontal ligament-like tissue; black arrows, ankylosis (replacement resorption).
