The maintenance of vitality of the cement periodontal ligament is important for success of tooth reimplantation. It has been suggested to minimize the period of exposure of the avulsed tooth to dry environment or keep it in wet storage. Recently, resveratrol has been extensively studied due to its antioxidant properties and ability to prolong the lives of several organisms since yeast to mammals. The aim of this study is to evaluate the maintenance of vitality of the cement periodontal ligament stored in resveratrol. The analysis was conducted using maxillary and mandibular incisors of three monkeys, total of 24 teeth. In group I the teeth were extracted and immediately immersed in fixative solution. In group II the teeth were maintained in dry environment for 6 hours. In group III the teeth were immersed in 50ml of solution of resveratrol in propylene glycol (5 μM/L) for 6 hours. The cuts were stained with H.E. for histomorphological analysis. The results demonstrated that in the group immediate showed presence of a moderate number of fibroblasts, some macrophages and lymphocytes. The dry group showed absence of blood vessels and fibroblasts in degeneration. In the group resveratrol 6 hours showed presence of small numbers of fibroblasts and mild vascularization. It was concluded that the resveratrol is adequate for maintenance of vitality of cells of periodontal ligament for 6 hours
