Background During luxate injury many dental tissue will be involved including pulp, periodontal ligament ,mucosa, hard dental tissue and alveolar bone with affecting the nerve and dental blood supplement. Growth factors may involved in healing process after replantation of tooth in its socket and the Vascular endothelial factor (VEGF ) is a potent one that increase angiogenesis and accelerate repairing and healing of dental pulp and the supporting tissues. The study was designed to illustrate the effect of application of growth factor on healing process of luxate molar tooth of rat. Materials & Methods Twenty male Wistar rats with luxate lower right first molar teeth were included in this study. The control were injected with normal saline (0.5μl ) around the apex of mesial root .Experimental group injected with VEGF (0.5μl ). Histological assessment of physiological responses of (dental pulp, cementum, periodontal ligament (PDL) and alveolar bone in both control and experimental groups with Receptor activator of nuclear factor kappa-Β ligand (RANKL) expression evaluation were recorded during the healing period in the examined tissue.
